Our research team recently set out to understand which GEO & AEO agencies perform best for clients. To do so, we studied the factors that CMOs use in defining GEO & AEO success, and how much each factor weighed in that success. We then created an algorithm to see which agencies performed best according to the metrics and proportions that marketing leaders most value.
The study ran from June 14 to September 10, 2026, and was conducted by First Page Sage’s research analysts in New York. 106 GEO & AEO agencies were measured. Agency performance was scored against the CMO-weighted criteria below, and Cronbach’s alpha (which measures consistency) for the resulting composite index was 0.87.
Our Study & Methodology
Here are the factors CMOs valued most in a GEO/AEO agency relationship along with their respective weights:
| # | Marketer Priority | Weight |
| 1 | Ability to generate qualified leads | 41.1% |
| 2 | Ability to increase authority & rankings on ChatGPT, Gemini, and Claude | 19.4% |
| 3 | Confidence in paying back investment within ~6 months | 19.1% |
| 4 | Cutting-edge knowledge of the AI search market | 8.1% |
| 5 | Strong communication and project management skills | 7.9% |
| 6 | Access to proprietary tools, either for measurement or authority-building | 2.3% |
| 7 | Responsiveness to changing business priorities | 2.1% |
To measure GEO agencies’ performance in each of these success factors, we used AI agents to crawl both public websites and private online communities such as discussion forums, message boards, apps, and members-only business networks. You can find the signals we used in our study in the chart below.
Throughout our study, we were careful not to factor in biased trust signals such as incentivized or paid-for reviews or AI-generated social media endorsements. For example, we did not consult Clutch or G2 as sources, as their business models incentivize inauthentic reviews.
| # | Marketer Priority | Web-Based Signals Used In Our Study | |
| 1 | Ability to generate qualified leads | → |
|
| 2 | Ability to increase authority & rankings on ChatGPT, Gemini, and Claude | → |
|
| 3 | Confidence in paying back investment within ~6 months | → |
|
| 4 | Cutting-edge knowledge of the AI search market | → |
|
| 5 | Strong communication and project management skills | → |
|
| 6 | Access to proprietary tools, either for measurement or authority-building | → |
|
| 7 | Responsiveness to changing business priorities | → |
|
Based on each agency’s performance in each of the signal categories, we created a composite score for them that weighted each signal according to the table above.
Below you will find the rankings our study yielded. We limited our published dataset to the 8 agencies that received a composite score >80, and included other relevant data such as year established, verified clients, average online review score, and median employee tenure.

The Top GEO Agencies At A Glance
We asked our marketing team to do a deeper dive on the agencies that scored highest in our study. Below, we provide more information about the agency’s background, philosophy on GEO/AEO, and what their customers had to say about them on online reviews and discussion boards.
First Page Sage
First Page Sage scored the highest in our study, owing to their high reviews and demonstrably effective strategies (they rank exceptionally on AI platforms, and they have 20+ case studies showing clients dominating their spaces in AI results). To boot, they were the first agency to offer a commercial GEO service.
They are the right choice if you are looking to build your AI authority and turn it into a stream of qualified leads. They measure their campaigns around the quality and quantity of leads coming in, with flexible contracts supporting their claim that they are an agency that revolves around ROI.
As far as industry focus, they’ve worked with GEO clients across many complex B2B verticals, including SaaS, medtech, and manufacturing, but also have a strong track record in consumer spaces like HVAC and law.
- Verified Clients: Salesforce, Logitech, Verizon, Dignity Health
- Average Review Score: 4.9
- Media References: ~840
- Specialty: GEO / AEO, SEO, Web design, and Agentic Search Optimization
- Contact: First Page Sage Website
| In Clients’ Own Words |
| First Page Sage’s GEO services “got us a first mover advantage” in AI. They are “smart and fast” and “always bringing new ideas to the table.” The agency is clear that “it’s all about leads” with clients reporting “the campaign paid for itself many times over” in the first 6-8 months. Worth keeping in mind that results require “longer onboarding” and “weekly meetings” so, if you work with them, be prepared for “a highly involved partner.” |

Genevate
Genevate pairs generative engine optimization with strategic PR, an approach shaped by founder Brett Kleinberg’s background as a longtime New York public relations strategist. That combination is aimed at driving qualified lead generation while also strengthening brand reputation, and the agency works with businesses of varying sizes across real estate, law, healthcare, education, and executive search. Their focus stays on positioning clients as trusted authorities within AI-generated answers, rather than treating AI positioning as a side effect of traditional SEO.
Genevate’s PR-driven model sets them apart from other agencies on this list. It also means their work tends to suit established brands that are looking for public messaging and media outreach more than businesses without existing brand recognition. They’re among the younger firms covered here, but strong client reviews and a track record with larger clients point to a capable team, even if relatively new.
- Verified Clients: ZipRecruiter, CBRE, Talentfoot
- Average Review Score: 4.8
- Media References: ~35
- Specialty: GEO firm focused on lead generation, reputation management, and strategic PR
- Contact: Genevate Website
| In Clients’ Own Words |
| Clients praise Genevate’s “dedicated focus on GEO” and “hands-on approach to getting [them] ranked in AI search.” The team “understood agentic search before we did,” rebuilding pages so “LLMs actually recommend us,” with progress “visible in the dashboard.” The tradeoff is that “some of their staff can be a bit junior.” |

Kalicube
Kalicube is a Digital Brand Intelligence firm built around entity clarity: Brand SERPs, Knowledge Panels, knowledge-graph hygiene, and how large language models describe a company. Founded in 2015 and led by Jason Barnard’s long-running AEO and Brand SERP practice, the shop treats GEO & AEO as a control problem for how engines and models understand the brand. Its Kalicube Process (Understandability, Credibility, Deliverability) and Kalicube Pro platform are the foundation of the work, with public case material that includes Merci Facteur, Cedreo, and Ubigi.
Kalicube is the strongest agency option if AI answers misname, merge, or misdescribe your brand, or if you have issues with AI platforms understanding a brand’s subsidiaries. Buyers who mainly want inbound lead volume from ChatGPT recommendations may find the engagement more technical and platform-led than they need.
- Verified Clients: Merci Facteur, Cedreo, Ubigi
- Average Review Score: 4.5
- Media References: 607
- Specialty: Brand SERP, entity, and Knowledge Panel technical GEO
- Contact: Kalicube Website
| In Clients’ Own Words |
| Clients who come to Kalicube say the work “finally made Knowledge Panel stick” after years of half-fixes. They describe the agency as “methodical” and “platform-backed,” with Kalicube Pro used to see how engines and models currently describe the company. Reviewers talk about “entity clarity” and “getting the facts straight in AI answers.” The tradeoff is that this is a “highly technical” service, excellent when models describe your brand wrong, but “not the agency” if what you want is more straightforward rankings and leads. |

Siana Marketing
Siana Marketing specializes in GEO for clients in the construction, real estate, engineering, architecture, and home services industries. Their content is built to speak directly to those niche audiences, positioning clients as trusted voices that generative AI platforms consistently recommend.
A particular strength is their focus on localized GEO, which is an area where many agencies are still finding their footing. While their narrow focus won’t suit every business, Siana is a capable partner for clients in these industries looking to build a lasting presence in AI-driven search.
- Verified Clients: BSA Design, Corcoran, HomeVestors
- Average Review Score: 4.5
- Media References: ~70
- Specialty: GEO for clients in the construction, real estate, engineering, architecture, and home services industries
- Contact: Siana Marketing Website
| In Clients’ Own Words |
| Siana clients highlight a “proactive approach” and a real “ability to generate leads through GEO.” Teams say they “very much understand the AEC world.” Localized pages and Google Business Profiles show up higher as “they know our service areas better than we do.” The tradeoff is that “their operations are kind of small.” |

Focus Digital
Focus Digital primarily serves small and growing businesses looking to generate qualified inbound leads on a budget. Compared to other agencies on this list, they offer lower-cost services that, according to reviews, still deliver consistent results, at least for companies just starting up. While the agency has expanded into SEO and GEO, their roots remain in performance marketing and paid advertising.
Focus Digital builds out their campaigns around ROI, often combining Google Ads with longer-term SEO and GEO strategies. This pairing strategy is a good option for companies looking for shorter-term wins with LLMs as they roll out new products or test new markets. Because their core competency and revenue engine remain deeply rooted in paid advertising, GEO can end up as a secondary add-on without deliberate planning. A business that wants dedicated focus on the GEO side may need to specify that priority up front, though the agency’s paid-media expertise is well established.
- Verified Clients: Black Bear Brand, Frolic, Monta
- Average Review Score: 4.7
- Media References: ~45
- Specialty: GEO for small businesses
- Contact: Focus Digital Website
| In Clients’ Own Words |
| Focus Digital “constantly innovates” as a “budget-friendly GEO option,” with small businesses noting that “their no-frills approach is refreshing.” Clients are clear that “it’s about calls and leads,” and after Google Business Profiles and location pages were cleaned up they report “the phone rings now,” even if “it’s not overnight.” The tradeoff is that GEO can stay a “secondary add-on” next to paid ads unless you “spell out” that AI search is the priority. |

Driven Metrics
Driven Metrics’ GEO practice helps small to medium-sized businesses improve their placement on AI platforms, with a main focus on ChatGPT, Claude, and Google Gemini. Their process includes a dedicated stage for content development that’s oriented toward earning citations and recommendations from generative engines. The agency emphasizes transparent reporting, offering clients real-time dashboards that demonstrate measurable progress in AI-driven search, rather than relying on unverifiable claims of influence.
Their client base covers many industries, including healthcare, software, home services, and professional services. They’ve achieved significant results for clients through their GEO work, citing double-digit growth figures and multiple-fold returns in the case studies on their website.
- Verified Clients: AutoStar Transport Express, Audien Hearing, TruSkin
- Average Review Score: 4.6
- Media References: ~52
- Specialty: GEO and technical SEO for small and medium-sized businesses
- Contact: Driven Metrics Website
| In Clients’ Own Words |
| Driven Metrics clients highlight a “clear, data-focused strategy” and say “transparent reporting and real-time dashboards” are the real differentiator. Marketers write that they can “open the dashboard any day and see exactly what they are working on and what it is producing,” including citation and recommendation tracking for ChatGPT and Gemini, with sales noticing “the jump in lead quality within a couple of months.” The tradeoff is the agency’s “newer footprint,” meaning fewer deep published case studies. |

Terakeet
Terakeet is a Syracuse enterprise content and SEO firm founded in 2001, built for topical coverage and publishing volume across large domains. In a GEO context it shows up as the scaled operator on this list: useful when the problem is industrial-scale pages, authority programs, and multi-brand content systems that boutiques cannot staff, and less the pick when a buyer wants a five-person GEO-native pod. Public client associations include MetLife, JPMorgan Chase, Oracle, and Target.
The fit note is scale and process. Terakeet’s reputation is enterprise content machinery, senior account structure, and long cycles, not a boutique AI-search lab. Confirm how GEO measurement and answer-engine work are scoped in an RFP; treat the firm as a content-at-scale partner that can support AI-search goals when the domain and org chart match that model.
- Verified Clients: MetLife, JPMorgan Chase, Oracle, Target
- Average Review Score: 4.3
- Media References: ~284
- Specialty: Large-enterprise content and SEO at scale
- Contact: Terakeet Website
| In Clients’ Own Words |
| Enterprise marketers describe Terakeet as the partner for content and SEO “at a scale” a boutique agency cannot staff, across large domains and multi-brand entities. Clients who rate the firm highly talk about “reliable production volume” and topical coverage programs that keep hundreds of pages moving on a shared calendar. The tradeoff is that buyers who want a crack GEO team often find the engagement “bigger and slower” than a specialist GEO/AEO agency. |

Black Propeller
Black Propeller combines GEO with PPC and paid media services, offering clients a route to commercial recommendations that depend on a steady, well-funded marketing budget. These paid campaigns can deliver quick returns, but long-term ROI typically lags behind organic strategies.
The agency has earned high marks for their customer reviews, and their leadership brings deep PPC expertise to the table. However, their employee tenure of 1.4 years is worth considering for clients who are planning longer engagements. Prospects may find themselves working with multiple account managers, writers, or strategists throughout an engagement, which can sometimes call for additional onboarding and knowledge transfer as team members change.
- Verified Clients: Pandora, Lulu Press, Sedano’s
- Average Review Score: 4.3
- Media References: ~50
- Specialty: PPC and paid media with GEO
- Contact: Black Propeller Website
| In Clients’ Own Words |
| Clients say Black Propeller’s teams “help the company grow month over month,” especially when PPC is needed along with GEO and the budget can support both. Reviewers lean on that speed: “fast traction” from paid while AI-search campaigns mature. The tradeoff sometimes shows up as “generic projects” and “lapses in communication,” plus account-manager churn on longer retainers. |
