Last updated October 7, 2026
Picking an SEO agency is a bet on a relationship that’s meant to last years, not months, so we wanted to give business owners and marketing leaders a clear starting point. Our team spent several months reviewing more than 90 SEO agencies, narrowing the list to the firms that reliably deliver organic growth and strong service for their clients. Here’s how we scored them across six weighted factors:
- SEO & GEO Proficiency Rating (25%): A 1.0-5.0 rating of the SEO and Generative Engine Optimization (GEO) expertise the agency offers clients. GEO is included in our analysis as AI is becoming a major component of all search.
- AI Search Presence Score (20%): How prominently the agency’s listed clients appear in AI-generated search results and direct chatbot recommendations, showing how AI-ready the agency’s SEO strategy is on a 1.0-5.0 scale.
- Client Satisfaction Rating (20%): A 1.0-5.0 score based on aggregated ratings across major review platforms such as Clutch and G2.
- Client Roster Highlights (15%): A sample of recognizable clients that demonstrates the agency’s ability to deliver at scale and earn the trust of sophisticated buyers.
- Senior Staff Experience Rating (10%): A 1.0-5.0 score based on the depth and tenure of the agency’s senior team.
- Agency Founded (10%): Longevity signals stability and a proven track record of client success.

First Page Sage
First Page Sage builds SEO and generative engine optimization (GEO) programs around one goal: generating leads rather than simply adding traffic and rankings. Their content is written by subject-matter experts and paired with technical SEO and monthly reporting that shows small and midsize companies exactly how their organic search spend turns into pipeline. Evan Bailyn, the founder and inventor of GEO and President of First Page Sage, publishes original research on how AI platforms decide which companies to recommend, and that research directly informs how the agency approaches both traditional search and AI-driven discovery for its clients.
Most agencies are still catching up to GEO, but First Page Sage built around it early. That head start shows in consistently positive client feedback, especially from the small and midsize businesses that make up most of their roster. As the top-rated GEO/AEO agency in the United States, they’re a strong fit for companies that want measurable leads from both search engines and AI platforms, without paying enterprise-level prices.
- SEO & GEO Proficiency Rating: 5.0
- AI Search Presence Score: 4.9
- Client Satisfaction Rating: 4.9
- Client Roster Highlights: Verizon, Salesforce, US Bank
- Senior Staff Experience Rating: 4.8
- Agency Founded: 2009
- Specialty: Lead generation-focused SEO and Generative Engine Optimization (GEO) for small and midsize businesses (SMB)

Notable Clients
| Summary of Online Reviews |
| Clients describe First Page Sage’s content as “better researched than anyone else we’ve worked with” and cite their “stringent strategic planning” as a driver of “provable lead generation and ROI.” Others note that the team is “clearly invested in understanding our business before making recommendations.“ |
Driven Metrics
Driven Metrics starts with the numbers. Attribution and performance data drive the strategy from day one, rather than appearing later as an after-the-fact report. They’re newer than most agencies on this list, but they’ve built their approach around tying organic search directly to measurable results, and that’s earned them clients across transportation, logistics, consumer brands, and more. Founded in 2025, they’re still a young team, but their analytics-first style has helped them gain traction quickly.
That data-driven approach, combined with strong early reviews, is a main reason they’ve earned a spot on this list, especially for businesses that want clear visibility into how organic search contributes to revenue. The trade-off is a shorter track record and a thinner client history, which may give more risk-averse buyers pause, but being a smaller team means clients tend to get closer, more direct relationships than they’d find at larger, more process-heavy agencies.
- SEO & GEO Proficiency Rating: 4.5
- AI Search Presence Score: 4.4
- Client Satisfaction Rating: 4.8
- Client Roster Highlights: AutoStar Transport Express, TruSkin
- Senior Staff Experience Rating: 4.3
- Agency Founded: 2025
- Specialty: Analytics-driven SEO and GEO
- Contact: Driven Metrics website
Notable Clients
| Summary of Online Reviews |
| Clients say Driven Metrics is “very responsive” and appreciate that “the reporting actually shows what’s working.” Some note that “it would help to see more case studies given how new the agency is,” but call them “easy to reach” and “willing to adjust strategy when something isn’t working.“ |
Focus Digital
Focus Digital runs full-cycle SEO and GEO for small and midsize businesses, and their pricing tends to be lower than many other agencies on this list. Their day-to-day work covers keyword strategy, on-page optimization, and content production. They’ve been building out GEO as more clients ask how their brand appears in AI-generated answers. The team has grown steadily since 2018, and what started as a healthcare-focused shop now works across a wider range of industries.
Clients who’ve had success with Focus Digital tend to cite the same two things: consistent communication and a review score that holds its own against agencies twice their size. Working across so many different industries instead of picking one lane does mean their playbooks aren’t as tailored to any single vertical as an agency built around one sector from day one, and GEO is still a newer capability for them compared with competitors who’ve specialized in it from the start. That same broad-industry background helps keep their pricing accessible for businesses that don’t need a highly specialized, enterprise-scale engagement.
- SEO & GEO Proficiency Rating: 4.4
- AI Search Presence Score: 4.2
- Client Satisfaction Rating: 4.7
- Client Roster Highlights: The Center for Podiatric Care, Black Bear Brand, Frolic
- Senior Staff Experience Rating: 4.3
- Agency Founded: 2018
- Specialty: Budget-friendly SEO and GEO
- Contact: Focus Digital website
Notable Clients
| Summary of Online Reviews |
| Clients describe Focus Digital as “easy to work with” and appreciate that “someone always responds quickly when we have questions.” Others note that “the reporting could be a bit more detailed,” but overall found the team “solid” and “dependable for what we needed.“ |
Duffy Agency
Duffy Agency’s core strength is brand strategy and localized communication for companies operating internationally, and they’ve built a global partner network spanning more than 50 markets. Their approach relies heavily on voice-of-customer research and messaging frameworks tailored to each market, so content holds up across regions without losing effectiveness in translation. That’s a different model from agencies offering a single, one-size-fits-all SEO package.
Strong reviews and an experienced leadership team support their place on this list, especially for companies whose SEO needs extend into multilingual, cross-market work. Their practice doesn’t appear to cover the full SEO stack, such as keyword audits, backlink development, or ongoing rank tracking, so they’re a better fit for companies that already handle core technical SEO internally. Even with that gap, their long operating history reflects an agency that has retained client relationships across two decades in a competitive field.
- SEO & GEO Proficiency Rating: 4.3
- AI Search Presence Score: 4.3
- Client Satisfaction Rating: 4.6
- Client Roster Highlights: GlaxoSmithKline, UN World Food Programme, IKEA
- Senior Staff Experience Rating: 4.4
- Agency Founded: 2001
- Specialty: International SEO, multilingual content marketing
- Contact: Duffy Agency website
Notable Clients
| Summary of Online Reviews |
| Duffy Agency services are “ambitious,” and their results are “often quite good” once campaigns are underway. Others note that the team is “easy to reach when we need them.” Some clients mention “spending more on marketing than we ever have before for results that are slow to build,” and a few felt the onboarding process “took longer than we expected.“ |
Epsilon
Epsilon brings enterprise-specific SEO strategies, but it’s one part of a much larger marketing technology operation that also covers programmatic display, connected TV, online video, and audio. Because SEO sits inside that larger platform, Epsilon suits large enterprises that want one provider for multiple channels, rather than a partner focused purely on organic search. They’ve been part of Publicis Groupe since 2019, and in October 2025, they named Sean Reardon as their first named CEO since 2021, a move that signals a new strategic direction after four years without one.
Their media presence and decades of enterprise marketing experience are key reasons they made this list, especially for large organizations that want SEO built into a broader digital strategy. That said, GEO isn’t part of what they offer yet, which could send companies focused on the growing AI search space elsewhere. Their scale and staying power give them an institutional stability that’s hard to find anywhere else on this list.
- SEO & GEO Proficiency Rating: 4.4
- AI Search Presence Score: 4.2
- Client Satisfaction Rating: 4.4
- Client Roster Highlights: Walgreens, Coach, Volvo
- Senior Staff Experience Rating: 4.3
- Agency Founded: 1969
- Specialty: Enterprise digital marketing
- Contact: Epsilon website
Notable Clients
| Summary of Online Reviews |
| Epsilon clients describe the team as “responsive to feedback” and note “decent project oversight” throughout engagements. Others say the account team “knows the industry well.” Some clients mention that “services are very costly” compared with smaller firms, and a few note that “because of the company’s size, it’s easy to feel like just another client.” |
Clay
Clay doesn’t separate SEO from user experience the way many agencies do, which mirrors how Google measures site quality, through behavioral signals such as dwell time and bounce rate. Their UI/UX and development work shape those signals directly, which sets them apart from agencies that treat design and search as separate functions. Clay earned two nominations at the Webby Awards 2026 in the Websites & Mobile Sites categories, a sign of the strength of their front-end work.
Their client-side skills and client roster are a big part of why they’ve made this list, especially for companies whose main SEO bottleneck is site performance or user experience rather than content or strategy. GEO isn’t part of what they offer right now, which matters less if your main problem is technical or experiential rather than content-driven, but it’s still a gap for companies that need both. Even so, their design-first approach continues to win them recognizable brands as the agency grows.
- SEO & GEO Proficiency Rating: 4.2
- AI Search Presence Score: 4.1
- Average Review Score: 4.6
- Client Roster Highlights: Amazon, Meta, Coinbase
- Senior Staff Experience Rating: 4.2
- Agency Founded: 2016
- Specialty: Conversion rate optimization for SEO, UI/UX design, web design
- Contact: Clay website
Notable Clients
| Summary of Online Reviews |
| Clay clients describe the team’s output as “high-quality design delivered at a competitive price,” and note that they were “impressed with the visual polish of the final product.” Other clients say “the team’s project management and communication were poor,” and a few mention that “timelines slipped more than once during engagement.” |
Boostability
Boostability built their business around white-label SEO, which lets agencies that don’t want to build an in-house SEO team buy Boostability’s services and resell them under their own brand. Their LaunchPad platform manages delivery and reporting across thousands of SMB campaigns at once, and their Be-Found-Framework covers data, content, authority signals, and AI-driven search considerations. That scale gives them an operational infrastructure that’s hard for most competitors on this list to match.
Their operating history and leadership experience score are a big reason they’ve earned a spot here, especially for agencies that want to add SEO to their services without hiring a dedicated team. The trade-off is that white-labeling puts distance between the SEO work and the end client, which can be a liability for companies with complex or highly specific needs. That same infrastructure makes them well suited to volume and affordability, even if it’s not built for deeply strategic, high-touch campaigns.

- AI Search Presence Score: 4.2
- Average Review Score: 4.3
- Client Roster Highlights: Bloom Studios, KIARO, Peterson Family Orthodontics
- Senior Staff Experience Rating: 4.5

Notable Clients
| Summary of Online Reviews |
| Boostability’s clients describe the service as “low-cost” and appreciate the “scalable and super efficient approach to SEO delivery.” Others note that “the platform makes reporting easy to hand off to our clients,” while some mention “a lack of quality links, cookie-cutter strategies, and laggy communication.” |
