The Best SaaS SEO agencies – According to real data
The 10 best SaaS SEO agencies, scored and ranked using publicly available reviews, performance & search visibility data
Andrew Fennell | Last updated 30 October 2026
Every SEO agency seems to publish a “best agencies” list with themselves at number one.
Sadly, that doesn’t make choosing one any easier.
This list is built on data – not opinion.
We scored the best 16 SaaS SEO agencies serving the US and UK across six categories, including third-party reviews, Google and AI visibility, and SaaS case studies
Filter by your company stage and budget to find your shortlist, explore the top 10 agency’s scores, or check the full methodology below.

How agencies are scored and ranked
Agencies are scored using publicly available data across six categories, weighted to calculate their overall ranking:
- Clutch Reviews - 30%: Review ratings and number of reviews.
- Google Visibility - 20%: Estimated traffic, keyword coverage and rankings for commercial SaaS SEO terms in the US and UK.
- AI Search Visibility - 20%: Frequency and position of appearances in ChatGPT and Google AI Overviews.
- Case studies - 20%: Number of qualifying SaaS case studies published.
- YouTube Presence - 5%: Subscribers and total channel views.
- LinkedIn Presence - 5%: Founder follower count.
The full methodology and a breakdown of each agency’s scores in every category are below.
The top 10 SaaS SEO agencies
Full score breakdowns and reviews
1. Intero Digital
Intero Digital is a large, full-service marketing agency, but it performs exceptionally well in SaaS SEO. Strong search visibility, plenty of client reviews and published results for software brands helped it take the top spot in this list.
Clutch Reviews 🏆
Intero’s 147 reviews and 4.8/5 rating gave it the strongest review score in our comparison. For potential clients, that means a substantial pool of third-party feedback to assess before making contact.
Category Winner 🏆
Google Visibility 🏆
Intero led our analysis of commercial SaaS SEO searches across the US and UK. Its ability to attract relevant search traffic to its own website is an encouraging signal for businesses looking for similar visibility.
Category Winner 🏆
AI Search Visibility
Intero didn’t appear in our five ChatGPT searches or five Google AI Overview searches. That held back its overall score and is worth discussing if visibility in AI recommendations is a priority for your business.
Case studies
With eight qualifying SaaS case studies. It wasn’t among the leaders for volume, but these give prospective clients examples of software-sector work to explore, and a starting point for requesting relevant references.
YouTube Presence
With 248 subscribers and 87,031 channel views, Intero scored well despite a relatively small subscriber base. Its videos give potential clients another way to assess the team’s thinking and communication before a sales call.
LinkedIn Presence
Intero scored strongly for founder follower count. This indicates an established professional audience and gives prospective clients another place to explore its leadership’s views, although audience size alone doesn’t demonstrate client results.
Intero's recent SaaS SEO client results
Sitecore: 32% more organic traffic and 605% growth in first-page rankings
Intero used technical and usability audits to identify improvements, followed by targeted on-page SEO. According to its case study, Sitecore grew from 59 first-page rankings to more than 400 within 10 months, alongside a 32% year-on-year increase in organic traffic.
PubMatic: 155% more first-page rankings within a year
PubMatic had plenty of useful content, but it wasn’t reaching enough potential customers. Intero audited the website and existing resources, then prioritised the biggest opportunities - reporting a 155% increase in first-page rankings within the first year, plus growth in traffic and leads.
2. Skale
Skale focuses specifically on SEO for SaaS & tech businesses and takes second place in our ranking. It stood out most in AI search visibility, earning the highest score in that category, alongside strong client reviews and a substantial collection of SaaS case studies.
Clutch Reviews
Skale’s 4.9/5 rating across 20 Clutch reviews shows consistently positive client feedback. Its review count is smaller than some competitors, but gives prospective clients a useful set of experiences to explore before making contact.
Google Visibility
Skale scored towards the lower end for visibility across the commercial SaaS SEO keywords we analysed in the US and UK. Its own search presence was less convincing than its reviews and case studies, so prospective clients should look closely at results for businesses with similar goals.
AI Search Visibility 🏆
Skale appeared in nine of our ten AI searches and took first place in seven of them, making it the clear winner in this category. That’s a strong signal of visibility in AI-generated agency recommendations - demonstrating sound knowledge of AI SEO best practice.
Category Winner 🏆
Case studies
We counted 16 qualifying SaaS case studies, giving potential clients plenty of relevant work to explore. That breadth makes it easier to find examples involving similar products, growth challenges or target audiences - and identify clients worth requesting references from.
YouTube Presence
Skale’s channel had 21 subscribers and 770 total views, giving it a relatively modest YouTube presence. There’s less video content and audience activity to assess than with some competitors, so its case studies and client feedback offer more useful evidence when building your shortlist.
LinkedIn Presence
Skale scored strongly for founder follower count, indicating an established professional audience. For potential clients, the founder’s posts provide another way to assess the agency’s thinking and approach before a call, though follower numbers alone don’t demonstrate delivery quality.
Skale's recent SaaS SEO client results
Perkbox: 40% more sales opportunities at £110 per opportunity
Skale combined technical SEO, content improvements and link building to target searches more likely to turn into customers. After 10 months, it reported 49.2% more non-brand organic clicks, a 40% increase in sales opportunities and a cost per opportunity of £110.
Jitter: 150% growth in AI visibility in four months
Skale helped motion design platform Jitter earn placements in third-party articles already cited by AI search tools. According to the case study, Jitter’s appearance rate across tracked prompts grew from 22% to 55%, while its average position in AI recommendation lists improved from 2.25 to 1.96.
3. SimpleTiger
SimpleTiger is a SaaS marketing agency covering SEO, AI search, content and paid advertising. It takes third place in our ranking, with strong client reviews and the second-highest AI search visibility score across the study.
Clutch Reviews
SimpleTiger’s 4.9/5 rating across 32 Clutch reviews earned it second place in this category. That combination of consistently positive ratings and a sizeable review history gives potential clients plenty of independent feedback to explore.
Google Visibility
SimpleTiger achieved a mid-table score for commercial SaaS SEO searches across the US and UK. It has a relevant search presence, but prospective clients should look at its case studies for evidence of how it performs in their particular software niche.
AI Search Visibility
SimpleTiger appeared in eight of our ten AI searches, earning the second-highest score behind Skale. Its regular inclusion in agency recommendations is an encouraging visibility signal for clients interested in being discovered through both Google and AI search.
Case studies
We counted 15 qualifying SaaS case studies, giving potential clients a useful range of software-sector projects to explore. These are a good starting point for finding examples with similar products, audiences or growth goals — and requesting relevant client references.
YouTube Presence
No qualifying agency or founder YouTube channel was recorded in our dataset. That means less video content for potential clients to assess.
LinkedIn Presence
SimpleTiger’s founder follower count earned it a lower score than most agencies in our comparison. The profile still gives prospective clients another way to explore the leadership’s thinking, but follower numbers carry only a small weight in our ranking and don’t establish client results.
SimpleTiger's recent SaaS SEO client results
Gainsight: 96% more top-three rankings and 67% more demo requests
SimpleTiger combined SEO and AI search optimisation with commercial content, link building and improvements to existing pages. After 10 months, it reported a 96% year-on-year increase in top-three keyword rankings, 67% more demo requests versus baseline and the highest AI search visibility among 459 tracked customer-success competitors.
Gelato: 1,200% more first-page rankings and a reported 3:1 ROI
SimpleTiger tackled technical and international SEO, improved commercial pages and supported a large-scale content and link-building programme. Within 12 months, Gelato ranked for 75,000 new keywords and increased its first-page keyword rankings by 1,200%, with SimpleTiger reporting a 3:1 return on investment.

4. MADX Digital
MADX Digital is a SaaS-focused SEO and AI search agency that takes fourth place in our ranking. It picked up points across all six categories, with a fairly balanced showing across client reviews, search visibility, case studies and audience presence; rather than relying on one standout result.
Clutch Reviews
MADX’s 4.9/5 rating across 14 Clutch reviews shows consistently positive client feedback. Its smaller review count held its score below some competitors, but gives prospective clients a useful set of experiences to explore.
Google Visibility
MADX earned third place for visibility across the commercial SaaS SEO searches we analysed in the US and UK. Its ability to compete for relevant buying keywords is an encouraging signal for SaaS businesses looking to attract customers through search.
AI Search Visibility
MADX appeared in three of our five ChatGPT searches, each time in seventh position, but didn’t appear in our Google AI Overview results. It has some visibility in AI recommendations, although prospective clients should look for examples of how its AI search services have performed for similar businesses.
Case studies
We counted 17 qualifying SaaS case studies, putting MADX comfortably in the upper half of the list for volume. That gives potential clients a range of software-sector projects to explore when assessing relevant experience and requesting references.
YouTube Presence
MADX’s channel had 127 subscribers and 5,190 total views. It’s a modest audience, but the videos give prospective clients another way to assess the agency’s knowledge and how clearly it explains its approach.
LinkedIn Presence
MADX’s founder follower count earned it a lower score than most agencies in our comparison. The profile still offers a way to explore its leadership’s thinking before a call, though audience size alone doesn’t demonstrate client results.
MADX's recent SaaS SEO client results
Postalytics: 16.8× organic traffic growth and 90% AI search share of voice
MADX built content hubs around Postalytics’ industries, product features and integrations, while fixing technical issues that limited visibility. It reports organic traffic growing from 4,916 to 82,505 monthly visits in 12 months, with Postalytics later achieving a 90% AI search share of voice across its tracked industry prompts in August 2026.
Nosto: 173% more top-three Google rankings and third place in AI search
MADX combined technical SEO, buyer-focused content and placements in third-party guides to improve Nosto’s visibility. According to the case study, keywords in Google’s top three grew from 56 to 153, while Nosto moved from no recorded AI search share of voice to third place among ten tracked competitors.
5. Rock The Rankings
Rock The Rankings focuses on SEO and AI search for B2B SaaS companies, taking fifth place in our ranking. Strong client reviews and 17 qualifying SaaS case studies helped it stand out, giving potential clients plenty of relevant work and feedback to explore.
Clutch Reviews
Rock The Rankings earned a perfect 5.0/5 rating across 14 Clutch reviews. Its smaller review count kept it below the category leaders, but the consistently positive feedback gives potential clients a useful starting point for assessing delivery and working relationships.
Google Visibility
Rock The Rankings scored towards the lower end for commercial SaaS SEO searches across the US and UK. Its own visibility was less convincing than its client reviews and case studies, so prospective clients should ask for examples of results in similarly competitive software markets.
AI Search Visibility
Rock The Rankings appeared in four of our ten AI searches, placing fourth to eighth when mentioned. That gave it a stronger showing than most agencies in this category, though its inclusion was less consistent than the leaders.
Case studies
We counted 17 qualifying SaaS case studies, putting Rock The Rankings in the upper half of the list for volume. That gives potential clients plenty of relevant projects to explore when looking for experience with similar products, audiences and growth challenges.
YouTube Presence
With 312 subscribers and 19,823 channel views, Rock The Rankings had a stronger YouTube presence than many agencies in our comparison. Its videos offer potential clients another way to assess the team’s knowledge and how clearly it explains its approach before a sales call.
LinkedIn Presence
Rock The Rankings earned a mid-range score for founder follower count. The founder’s profile provides another place to explore the agency’s thinking and professional activity, although audience size alone doesn’t demonstrate client results.
Rock the Ranking's recent SaaS SEO client results
Lendbuzz: 200% more organic signups and visibility across 21 of 23 AI prompt themes
Rock The Rankings built commercial landing pages and content around borrowers’ specific needs, then targeted relevant AI recommendations. According to its case study, organic signups increased by 200% year on year, while Lendbuzz appeared in 21 of 23 tracked AI prompt themes.
Choicely: 41× trial signups and 36% of demos becoming opportunities
Rock The Rankings created bottom-of-funnel pages designed to answer buying questions and earn citations in AI search. It reports trial signups reaching 41 times the April baseline by July, with 36% of demos in the latest measured cohort progressing to sales opportunities.
6. uSERP
uSERP specialises in link building and digital PR, alongside SEO and AI search services. It takes sixth place in our ranking, standing out with the largest collection of qualifying SaaS case studies and a strong Clutch review profile - giving potential clients plenty of evidence to explore.
Clutch Reviews
uSERP’s 4.9/5 rating across 21 Clutch reviews earned it third place in this category. That gives potential clients a solid collection of third-party feedback to assess alongside the agency’s own case studies.
Google Visibility
uSERP scored towards the lower end for the commercial SaaS SEO searches we analysed across the US and UK. As a link-building specialist, its visibility for these terms only tells part of the story, so prospective clients should also explore results from campaigns matching their needs.
AI Search Visibility
uSERP didn’t appear in our five ChatGPT searches or five Google AI Overview searches. That limited its overall score and makes client examples worth requesting if appearing in AI recommendations is a priority for your business.
Case studies 🏆
We counted 42 qualifying SaaS case studies - the largest collection in our comparison. That breadth gives potential clients more opportunities to find relevant examples and assess uSERP’s experience with similar products, markets and growth challenges.
Category Winner 🏆
YouTube Presence
uSERP’s recorded channel had 28 subscribers and 748 total views, giving it a relatively modest YouTube presence. There’s less video material for potential clients to assess, making its reviews and case studies more useful starting points.
LinkedIn Presence
uSERP earned the second-highest score for founder follower count, indicating a substantial professional audience. The founder’s profile offers potential clients another way to explore the agency’s thinking and expertise, although audience size alone doesn’t establish client results.
uSERP's recent SaaS SEO client results
monday.com: 77.8% more organic traffic and 23,543 new ranking keywords
uSERP supported monday.com’s content production, on-page optimisation and link building, helping it compete for valuable project management searches. The case study reports monthly organic traffic growing from 677,000 to more than 1.2 million, alongside 23,543 new ranking keywords and 825 first-page positions.
Preply: 203.8% more organic traffic and a number-one ranking for “Spanish tutor”
uSERP focused on earning relevant brand mentions and backlinks from authoritative publications to strengthen Preply’s search presence. According to the case study, it secured more than 450 backlinks from DR50+ websites, while monthly organic traffic grew from 790,000 to over 2.4 million and Preply reached first place for “Spanish tutor”.
7. Omniscient Digital
Omniscient Digital is a B2B organic growth agency covering SEO, content and AI search. It takes seventh place in our ranking, with its strongest showing in AI recommendations, alongside a sizeable collection of SaaS case studies and an active YouTube presence.
Clutch Reviews
Omniscient’s 4.8/5 rating across six Clutch reviews shows positive feedback, but its smaller review count limited its score. Potential clients have fewer independent experiences to explore, making relevant references worth requesting.
Google Visibility
Omniscient scored towards the lower end for commercial SaaS SEO searches across the US and UK. Its own visibility for these terms was limited, so prospective clients should look closely at results for software businesses with similar audiences and goals.
AI Search Visibility
Omniscient appeared in all five ChatGPT searches, consistently placing second or third, plus one Google AI Overview result. That made it a regular recommendation in our test - a useful visibility signal for clients interested in how buyers discover agencies through AI search.
Case studies
We counted 15 qualifying SaaS case studies, giving potential clients a useful range of software-sector projects to explore. These provide a starting point for assessing relevant experience and asking how the agency would approach similar challenges for your business.
YouTube Presence
With 505 subscribers and 47,223 total channel views, Omniscient earned third place in this category. Its videos give potential clients more opportunities to assess the team’s thinking, expertise and communication before arranging a call.
LinkedIn Presence
Omniscient scored strongly for founder follower count, indicating an established professional audience. The founder’s profile offers another way to explore the agency’s views and approach, though follower numbers alone don’t demonstrate client results.
Omniscient's recent SaaS SEO client results
OnBoard: 88% AI search visibility and double the meetings from AI referrals
Omniscient combined content updates, digital PR, Reddit engagement and technical improvements to strengthen OnBoard’s presence in AI answers. The case study reports appearances in 88% of tracked category prompts by August 2026, with meetings booked from AI-referred traffic doubling month on month.

8. Scalerrs
Scalerrs focuses on SEO, AI search and content for SaaS businesses, taking eighth place in our ranking. It picked up points across all six categories, with a solid showing in Google visibility and 18 qualifying SaaS case studies for potential clients to explore.
Clutch Reviews
Scalerrs earned a perfect 5.0/5 rating across six Clutch reviews. The feedback is encouraging, but the smaller review count limited its score - making relevant client references worth requesting before committing.
Google Visibility
Scalerrs earned fourth place for visibility across the commercial SaaS SEO searches we analysed in the US and UK. Its ability to compete for relevant buying keywords is a positive signal for businesses looking to attract customers through organic search.
AI Search Visibility
Scalerrs appeared in just one of our ten AI searches, taking first position in a Google AI Overview result. That top placement helped its score, but its limited appearance rate means prospective clients should ask for broader evidence of AI visibility results.
Case studies
We counted 18 qualifying SaaS case studies, putting Scalerrs joint third for volume alongside Breaking B2B. That gives potential clients a substantial range of software-sector work to explore when assessing experience with similar products and growth challenges.
YouTube Presence
Scalerrs’ channel had 26 subscribers and 1,178 total views, giving it a modest YouTube presence. There’s less video material to assess than with some competitors, so its case studies and client feedback offer more useful starting points.
LinkedIn Presence
Scalerrs scored strongly for founder follower count, placing it among the larger professional audiences in our comparison. The founder’s profile gives potential clients another way to explore the agency’s thinking, although audience size alone doesn’t demonstrate delivery quality.
Scalerrs' recent SaaS SEO client results
Simplestream: 50% more non-brand traffic
Scalerrs combined a technical SEO audit, website improvements and ongoing content aimed at Simplestream’s technical B2B audience. The case study reports a 50% increase in non-brand traffic, alongside improved website health and stronger AI search visibility.
Ignition Benefits: 33% of leads from inbound within six months
Scalerrs supported Ignition’s launch with technical SEO, AI search optimisation, content, backlinks and Reddit marketing. After around six months, the case study reports that inbound generated 33% of leads and at least one qualified meeting per day, with priority non-brand searches bringing approximately 1,500 monthly clicks.
9. Breaking B2B
Breaking B2B focuses on SEO and AI search for B2B and SaaS companies, taking ninth place in our ranking. It stood out with the strongest YouTube and founder LinkedIn presence, plus the second-highest Google visibility score, although no Clutch reviews were recorded in our dataset.
Clutch Reviews
No Clutch reviews were recorded for Breaking B2B, so it received no points in this category. That leaves potential clients with less third-party feedback to assess, making direct client references particularly useful.
Google Visibility
Breaking B2B earned second place for commercial SaaS SEO visibility across the US and UK. Its ability to attract relevant buying traffic to its own website is an encouraging signal for businesses seeking similar search visibility.
AI Search Visibility
Breaking B2B appeared in two of our five Google AI Overview searches, taking fourth position both times, but didn’t appear in ChatGPT. That shows limited visibility in AI recommendations for SaaS SEO enquiries.
Case studies
We counted 18 qualifying SaaS case studies, putting Breaking B2B joint third for volume alongside Scalerrs. This gives potential clients a substantial range of relevant projects to explore when assessing experience with similar products and growth challenges.
YouTube Presence 🏆
With 3,780 subscribers and 366,195 total views, Breaking B2B led our YouTube comparison. Its video library gives potential clients plenty of opportunity to assess the team’s knowledge, and shows clear thought leadership in the B2B SaaS SEO space.
Category Winner 🏆
LinkedIn Presence 🏆
Breaking B2B also earned the highest score for founder follower count. That established audience offers another way to explore the founder’s thinking and professional activity, although popularity alone doesn’t demonstrate client results
Category Winner 🏆
Breaking B2B's recent SaaS SEO client results
Fibbler: 10× organic traffic within six months
Breaking B2B took over Fibbler’s SEO and AI search programme, targeting buying queries while keeping the founder’s voice in its content.

It reports a 77% increase in non-branded organic traffic within six months, adding a new acquisition channel alongside LinkedIn and cold email.
10. Minuttia
Minuttia focuses on content-led growth across Google and AI search, taking tenth place in our ranking. Strong client reviews, a sizeable founder audience and the second-highest YouTube score helped it stand out, although it recorded no visibility in our Google or AI search tests.
Clutch Reviews
Minuttia’s 4.9/5 rating across 16 Clutch reviews shows consistently positive client feedback. That gives prospective clients a useful pool of independent experiences to explore when assessing communication, delivery and results.
Google Visibility
Minuttia recorded no rankings in the filtered commercial SaaS SEO keyword dataset we analysed across the US and UK. That limits the evidence from its own visibility for these searches, so potential clients should look closely at relevant client campaigns.
AI Search Visibility
Minuttia didn’t appear in our five ChatGPT searches or five Google AI Overview searches. This held back its overall score, making client examples worth requesting if visibility in AI recommendations is a priority.
Case studies
We counted 12 qualifying SaaS case studies, giving potential clients a reasonable selection of software-sector projects to explore. These offer a starting point for assessing experience with similar products, audiences and content challenges.
YouTube Presence
With 703 subscribers and 41,119 total channel views, Minuttia earned second place in our YouTube comparison. Its videos give potential clients plenty of opportunity to assess the team’s thinking and how clearly it explains its approach before a sales call.
LinkedIn Presence
Minuttia scored strongly for founder follower count, placing it among the larger professional audiences in our comparison. The founder’s profile offers another way to explore its content and search expertise, although follower numbers alone don’t demonstrate client results.
Minuttia's recent SaaS SEO client results
Toggl: 7 million impressions and 26,000+ clicks from 91 content pieces
Minuttia helped Toggl scale content production with keyword research, writing, custom graphics and a three-stage review process. Over 15 months, the case study reports more than 7 million search impressions and 26,000 clicks from 91 articles and updates, targeting mainly high-intent searches.
Respona: From zero to 100,000 monthly organic visits in 26 months
Minuttia built a product-led content strategy, prioritised keyword opportunities and created approximately 100 blog posts for Respona. According to the case study, the site reached around 100,000 monthly organic visits and ranked for more than 20,000 keywords, with over 40 Minuttia-created posts appearing in positions one to three.
How we scored and ranked the agencies
Methodology + League tables for each category
Most “best SaaS SEO agencies” lists follow a familiar pattern: an agency puts itself first, praises a few competitors and offers little evidence to help you choose.
Here at RevPages, we wanted to create something more useful.
We compared 16 agencies using publicly available data across six factors that matter to potential clients: customer feedback, Google visibility, AI recommendations, SaaS case studies and professional audience presence.
| Rank | Agency | Clutch Reviews 30% | Google Rankings 20% | AI Search Visibility 20% | Case studies 20% | YouTube Presence 5% | LinkedIn Presence 5% | Total score 100 |
|---|---|---|---|---|---|---|---|---|
| 1 | Intero Digital | 86.3 | 78.7 | 0 | 44.4 | 77.9 | 88.6 | 58.83 |
| 2 | Skale | 64 | 10.1 | 87.9 | 61.5 | 44.7 | 91.1 | 57.89 |
| 3 | SimpleTiger | 73.2 | 24.6 | 75.2 | 60 | 0 | 77.6 | 57.8 |
| 4 | MADX Digital | 56 | 47.2 | 24.6 | 63 | 62.8 | 77.6 | 50.78 |
| 5 | Rock The Rankings | 58.3 | 11.4 | 34 | 63 | 73.5 | 84.1 | 47.05 |
| 6 | uSERP | 65.1 | 9.8 | 0 | 80.8 | 46.3 | 99.6 | 44.94 |
| 7 | Omniscient Digital | 34.6 | 9.5 | 56.4 | 60 | 79.8 | 88.6 | 43.98 |
| 8 | Scalerrs | 37.5 | 33 | 10 | 64.3 | 47.6 | 92.1 | 39.7 |
| 9 | Breaking B2B | 0 | 64.5 | 18.2 | 64.3 | 100 | 100 | 39.4 |
| 10 | Minuttia | 59.1 | 0 | 0 | 54.5 | 81.3 | 92.6 | 37.33 |
Each agency received a score out of 100 for every category. We then applied the weightings below and added the contributions together to calculate its overall score. Client reviews carry the most weight, while YouTube and LinkedIn have smaller contributions because audience size is a less direct measure of delivery.
The result is a starting point for your shortlist. It makes the evidence easier to compare, but your product, budget and working relationship will determine which agency is right for you.
Clutch Reviews (30%)
Why we included it
Client feedback is the most important part of our assessment. Clutch specialises in reviews of agencies and other business service providers, giving buyers detailed accounts of real projects outside the agency’s own website. It checks reviewer identities and project details, although some reviews can be published with a “Not Verified” label.
How we scored it
We recorded each agency’s average Clutch rating and total review count, combining both into its category score. This rewards consistently positive feedback supported by a larger review history, rather than treating one five-star review as equivalent to dozens.
Why the weighting
Reviews account for 30% of the overall score (the largest contribution) because previous clients’ experiences usually offer the best evidence about communication, reliability and delivery.

Google Visibility (20%)
Why we included it
If you’re hiring an agency to improve your organic search traffic, its ability to attract relevant traffic to its own website is worth looking into. Competing for commercial SaaS SEO searches proves they don't just talk a good game - they can put their own advice into practice.
How we scored it
We used Ahrefs’ Organic Keywords report for each agency in both the US and UK, filtering for the phrase “saas seo” and commercial, non-branded intent.
We assessed estimated organic traffic, the number of ranking keywords and ranking positions, with additional credit for AI Overview appearances where recorded. Combined estimated traffic across both countries was the biggest factor, with keyword coverage and positions providing supporting measures.
Why the weighting
Google visibility contributes 20%. It is relevant evidence of search performance, even though it's probably not something most agencies would include in their proposal.
AI Search Visibility (20%)
Why we included it
Buyers now frequently get recommendations from within inside AI-generated answers. We wanted to measure which agencies appeared when asked a question close to what a potential SaaS client might search.
How we scored it
We ran the following prompt five times in ChatGPT and five times in Google AI Overviews:
"Who are the best SEO agencies to help SaaS businesses increase organic traffic and signups?"
For each run, we recorded whether an agency appeared and its position in the recommendation list. Agencies scored more highly for appearing consistently and nearer the top, with equal weight given to the two platforms.
Why the weighting
AI visibility contributes 20%, reflecting its importance alongside traditional search, especially for buyers close to selecting a vendor.
Case studies (20%)
Why we included it
Case studies let potential clients explore an agency’s experience in more depth: the industries it understands, the problems it tackles and the results it reports in traffic and revenue increases. They also provide a starting point for requesting relevant client references.
How we scored it
We reviewed agency websites and counted the qualifying, publicly accessible SaaS case studies identified in our research. Higher counts earned higher scores, with diminishing returns so that a very large collection could not dominate the category.
We measured the availability of relevant examples, rather than attempting to compare headline growth percentages from very different campaigns.
Why the weighting
Case studies contribute 20%, below Clutch reviews. They provide useful detail, but agencies select which projects to publish, and their reported results are not independently audited.
YouTube Presence (5%)
Why we included it: YouTube is an important platform for search and discovery. Building an audience there can demonstrate useful content and distribution skills, while longer videos give prospective clients a chance to assess an agency’s expertise and communication before a sales call.
How we scored it: We recorded subscriber numbers and total channel views for the agency or founder channel included in our dataset. Both measures contributed to the score, using logarithmic scaling to reduce the influence of exceptionally large channels.
Why the weighting: YouTube contributes 5%. An established channel is useful supporting evidence, but subscribers and lifetime views do not establish the quality of client work or prove that views came from organic search.
LinkedIn Presence (5%)
Why we included it: A founder’s LinkedIn profile gives potential clients another way to explore the thinking behind an agency. An established following can indicate that its content has attracted professional interest and offer a useful library of advice, opinions and discussions to assess.
How we scored it: We recorded the follower count of the founder profile selected for each agency and converted it into a comparable score, using logarithmic scaling to prevent the largest audiences from overwhelming the results. We did not score engagement or audit how those followings were acquired.
Why the weighting: LinkedIn contributes 5%. It is a supporting signal of professional presence, rather than a direct measure of SEO ability, client satisfaction or campaign results.
