Last updated: July 24, 2026
Our team evaluated 63 SaaS-centered SEO agencies to determine the most successful firms based on their SaaS industry experience. We rank-ordered the companies using the following criteria:
- Notable Clients (30%): An agency’s experience with notable SaaS clients is the best indicator of their ability to run successful SEO campaigns. As such, it is the factor we assign the most weight to.
- Leadership Experience (20%): We assigned each company a numerical score from 1 to 5 based on the SaaS marketing experience of each agency’s top executives and marketing leadership.
- Median Employee Tenure (15%): Longer employee tenure indicates that an agency is dedicated to employee growth and the training required to execute complex SaaS SEOcampaigns.
- Average Review Score (10%): How satisfied clients are when leaving reviews for an SEO agency correlates positively with their ability to deliver results.
- GEO Offering (10%): We favor agencies that indicate they’ve begun offering services to help their clients rank on AI platforms in addition to Google search.
- Year Established (5%): Despite being a relatively new marketing industry, SEO has evolved significantly over the past 15 years. The length of a company’s tenure displays its ability to update its SEO strategy as Google updates its algorithm, as well as weather market cycles and economic downturns.
- Founder Led (5%): We give a slight advantage to agencies whose original leadership remains with them, either in a direct management or consulting role.
- Media References (5%): A minor factor in our analysis is how many times each agency’s publications have been cited by news and other high authority sources.
For each agency below, we also provide their main focus and describe their unique approach to SEO. The results of our research are presented in the table below:

First Page Sage
First Page Sage has built its SaaS practice around the content formats that move software buyers through the funnel: product comparison pages, use-case landing pages, and thought leadership articles that target the high-intent queries prospects search when evaluating solutions. For SaaS clients, this has meant ghostwriting content that captures decision-makers at the research stage and converts organic visits into demo requests and trial signups.
As AI platforms like ChatGPT, Perplexity, and Google’s AI Overviews have become a primary discovery channel for SaaS buyers, First Page Sage has adapted its methodology to include generative engine optimization (GEO), helping clients surface in AI-generated recommendations alongside traditional search results. Their additional services include conversion rate optimization and SEO audits.

REQ
REQ is a hybrid marketing agency that blends traditional advertising and SEO to create a uniform brand strategy for its clients across various marketing channels. Their services include on-page and off-page SEO, traditional PR, and social media, in addition to their branding, UX, and SEO work.
REQ’s branding specialization and traditional advertising emphasis make them best suited for larger SaaS companies seeking to reinvent their image. While they also work well with smaller companies, the cost of their services is often outside the marketing budget of SaaS startups.

Clay Agency
Clay Agency‘s focus is on the UX design and conversion optimization side of SEO. Their full-stack web design and development helps clients turn organic traffic into leads by improving site structure, page experience, and calls to action. Because of this conversion focus, the best fit for Clay Agency’s services is SaaS companies that have strong organic traffic, but fail to capitalize on it to generate leads.
Clay Agency has done notably well for itself within the SaaS vertical, working with several highly notable clients that have given them a firm commend of the vertical’s unique nuances. Their services are currently limited to more traditional SEO, which may exclude them from clients seeking to branch out into AI-related campaigns (e.g., GEO, AEO, ASO), however they remain a strong option within the traditional vertical.

- Median Employee Tenure: 2.4 years
- Average Review Score: 4.6
- Offers GEO?: No
- Year Founded: 2016

Focus Digital
Focus Digital provides SEO and GEO services for growing SaaS companies, centering its work on qualified lead generation and measurable ROI over traffic volume. Their content strategy targets high-intent keywords relevant to SaaS buyers at the evaluation stage, and their GEO offering helps clients gain recommendations across AI platforms like ChatGPT and Perplexity. Pricing is positioned toward growth-stage companies, making them a more accessible option than many of the larger agencies on this list.
Focus Digital’s accessibility comes with scope constraints. SaaS companies seeking a full-service marketing partner may find Focus Digital’s offering narrower than agencies like REQ or Kalungi. Nonetheless, the agency has extensive experience within the SaaS vertical, with an average customer review score that suggests an ability to reliably meet the needs of clients.
- Notable Clients: Shadeform, Synopsys, Eudia
- Leadership Experience Score: 4.3
- Median Employee Tenure: 2.8 years
- Average Review Score: 4.8

Marketing Eye
Marketing Eye specializes in technical SEO, with web development as its primary service. They also offer strategic consulting to clients that already have an in-house marketing team but have more limited capabilities than many of the other agencies on this list.
This makes them a better fit for SaaS companies with writing teams that can create their own content for Marketing Eye to optimize. Notably, Marketing Eye has not yet expanded into GEO, which may be a limiting factor for SaaS companies looking to capture visibility on AI platforms like ChatGPT and Perplexity alongside traditional search.
- Notable Clients: Construx Solutions, Innovent CRM, JESI
- Leadership Experience Score: 4.0
- Median Employee Tenure: 7.1 years
- Average Review Score: 4.4
- Offers GEO?: No
- Year Founded: 2004
- Founder Led: Yes
- Media References: ~20
- Specialty: Technical SEO and web design for SaaS companies
| Summary of Online Reviews |
| Marketing Eye provides “competent and professional” work, though some clients note they would have valued “more proactive strategic guidance” alongside the technical execution. |
Metric Theory
Metric Theory combines paid search, SEO, and visitor tracking to create multiple touchpoints that help searchers convert. They supplement search rankings through remarketing display ads and social media, creating lasting impressions in their target audience. Because their approach relies heavily on paid search, they work best with SaaS companies that prioritize rapid results over ROI.
Because Metric Theory’s menu of services is primarily focused on a mix of SEO and PPC, SaaS companies seeking AI-centric offerings (e.g., GEO, AEO, ASO) may be better positioned with another agency. Within this niche, however, their teams provide excellent services for SaaS clients at varying degrees of scale.
- Notable Clients: Zenefits, Optimizely, Zuora
- Leadership Experience Score: 4.3
- Median Employee Tenure: 3.1 years
- Average Review Score: 4.6
- Offers GEO?: No
- Year Founded: 2012
- Founder Led: Yes
- Media References: ~110
- Specialty: Combined SEO & paid search
| Summary of Online Reviews |
| Metric Theory excels in background research that is both “thorough“ and “effective“, but occasionally clients feel their team would “benefit from having more resources“. |
Kalungi
Kalungi offers fractional marketing teams for SaaS companies, functioning as an outsourced marketing department rather than a traditional agency. Their services span SEO and content, paid media, website development, GTM strategy, and CMO-as-a-service, with SEO being one component of a broader growth engine rather than a standalone offering. On the SEO side, they build comparison pages, competitor alternative pages, and use-case content designed to capture demand during vendor evaluation.
While Kalungi notes that their content “gets cited by AI systems,” their GEO offering is folded into their broader SEO service rather than delivered as a distinct methodology, making it less clear how they measure AI-platform visibility as a standalone outcome. This makes them a good fit for early-stage B2B SaaS startups that need to build an entire marketing function from scratch, but a less natural fit for companies specifically seeking a dedicated SEO or GEO partner.
- Notable Clients: Zippity, Beezy, Arrowstream
- Leadership Experience Score: 3.8
- Median Employee Tenure: 3.2 years
- Average Review Score: 4.1
- Offers GEO?: Yes
- Year Founded: 2018
- Founder Led: Yes
- Media References: ~200
- Specialty: Full-service fractional marketing for early-stage B2B SaaS companies
| Summary of Online Reviews |
| Clients describe Kalungi’s team as “kind and professional,” though some note the engagement can feel more people-focused than strategy-focused at times. |
RNO1
RNO1 prioritizes market research and design, offering comprehensive brand explorations for SaaS clients seeking to create a unique brand identity. They also emphasize the importance of strong UI/UX design, creating unique digital experiences for visitors to the clients’ websites.
They work best with innovative SaaS startups, particularly those focused on Web3, that need strong technical SEO foundations like site architecture, page speed, structured data, and crawlability paired with premium brand and UX design. Their design-centric approach does make them a poor fit for SaaS companies that need content-led SEO or GEO, as neither is part of their core offering.
- Notable Clients: Prive, TakeUp, Fluxa
- Leadership Experience Score: 3.7
- Median Employee Tenure: 5.8 years
- Average Review Score: 4.4
- Offers GEO?: Yes
- Year Founded: 2009

- Specialty: Market research and UX design for SaaS startups
| Summary of Online Reviews |
| RNO1 delivers “strong brand and design work” and is described as “responsive,” though some clients note that their scope is narrow and wish they offered “more full-service marketing support.” |
