Picking an SEO agency is a bet on a relationship that’s supposed to last years, not months, so we wanted to give business owners and marketing leaders a real place to start. It took our team a few months to work through more than 90 SEO agencies, narrowing the list down to the firms that consistently deliver organic growth and excellent service for their clients. Here’s how we scored them, based on six weighted factors:
- SEO & GEO Proficiency Rating (25%): A 1.0-5.0 rating on the level of SEO and Generative Engine Optimization (GEO) expertise the agency can offer clients. We included GEO in our analysis since that is the direction search is headed.
- AI Search Presence Score (20%): How prominently the agency’s listed clients appear in AI-generated search results and direct chatbot recommendations, to prove 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 on the aggregated ratings across major review platforms like Clutch and G2.
- Client Roster Highlights (15%): A sampling of any recognizable clients to demonstrate 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 members.
- Agency Founded (10%): Longevity signals stability and a demonstrated track record of client success.

First Page Sage
First Page Sage builds SEO and generative engine optimization (GEO) programs around one goal: generating leads instead of just racking up traffic and rankings. Their content is written by actual subject-matter experts, paired with technical SEO and monthly reporting that shows small and midsize companies exactly how their organic search spend is turning into a 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 work has directly shaped 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 was building around it early. That head start shows in how consistently their clients speak well of them, especially 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 solid fit for companies that want real, measurable leads from both search engines and AI platforms, without paying enterprise-level prices to get there.
- 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)
- Contact: First Page Sage website
| Summary of Online Reviews |
| Clients describe First Page Sage’s content as “better researched than anyone else we’ve worked with” and point to 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.” |
Focus Digital
Focus Digital runs full-cycle SEO and GEO for small and midsize businesses, and their pricing tends to be friendlier than a lot of the other names on this list. Their day-to-day work not only covers keyword strategy, but also on-page optimization and content production. They’ve been building out GEO as more clients start asking how their brand shows up in AI-generated answers. The team has grown steadily since 2018, and what started as a healthcare-focused shop now works across a much wider mix of industries.
Clients who’ve had success with Focus Digital tend to bring up the same two things again and again, which is 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 muscle for them compared to competitors who’ve specialized in it from the start. That same broad-industry background is part of what keeps their pricing accessible for businesses that don’t need a highly specialized, enterprise-scale engagement.
- SEO & GEO Proficiency Rating: 4.5
- AI Search Presence Score: 4.2
- Client Satisfaction Rating: 4.8
- 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
| 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 to be “solid” and “dependable for what we needed.” |
Driven Metrics
Driven Metrics starts with the numbers first. Attribution and performance data drive the strategy from day one, rather than showing up later as something to report on after the fact. They’re newer than most agencies on this list, but they’ve built their whole approach around tying organic search directly to results you can actually measure, 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 fast.
That data-driven approach, paired with strong early reviews, is a big part of why they’ve earned a spot on this list, especially for businesses that want real visibility into how organic search is contributing 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: 4.4
- AI Search Presence Score: 4.4
- Client Satisfaction Rating: 4.7
- 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
| 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,” though most describe the team as “easy to reach” and “willing to adjust strategy when something isn’t working.” |
Duffy Agency
Duffy Agency’s real strength is brand strategy and localized communication for companies operating internationally, and they’ve build out a global partner network that spans more than 50 markets. Their approach leans heavily on voice-of-customer research and messaging frameworks tailored to each market, so content actually holds up across regions without losing effectiveness in translation. That’s a different lane than agencies offering a single, one-size-fits-all SEO package.
Strong reviews and an experienced leadership team back up their spot on this list, especially for companies whose SEO needs stretch into multilingual, cross-market territory. 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 have core technical SEO handled internally. Even with that gap, their long operating history reflects an agency that has kept 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
| Summary of Online Reviews |
| Duffy Agency services are “ambitious,” and their results are “often quite good” once campaigns get 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 just one piece of a much bigger marketing technology operation that also covers programmatic display, connected TV, online video, and audio. Because SEO sits inside that larger platform, Epsilon works best for large enterprises that want one provider handling 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 fresh strategic direction after four years without one.
Their media presence and decades of enterprise marketing experience are a big part of why 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 a kind of 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
| 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 to 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 a lot of agencies do, and that mirrors how Google actually 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 two unrelated jobs. Clay earned two nominations at the Webby Awards 2026 in the Websites & Mobile Sites categories, a signal of how strong their front-end work really is.
Their client-side skills and client roster are a big part of why they’ve made this list, especially for companies whose real 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 real gap for companies that need both. Even so, their design-first approach keeps landing them recognizable brands as the agency continues to grow.
- 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
| 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,” with a few mentioning that “timelines slipped more than once during engagement.” |
Boostability
Boostability built their entire business around white-label SEO, letting 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 handles 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 kind of 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 what they offer without hiring a dedicated team. The trade-off is that white-labeling puts a layer of distance between the actual SEO work and the end client, which can be a real liability for companies with complex or highly specific needs. That same infrastructure is what makes them so well-suited for volume and affordability, even if it’s not built for deeply strategic, high-touch campaigns.
- SEO & GEO Proficiency Rating: 4.1
- 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
- Agency Founded: 2009
- Specialty: White-label SEO for digital marketing agencies
- Contact: Boostability website
| 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 clients mention “a lack of quality links, cookie-cutter strategies, and laggy communication.” |
