AI systems now do more than make recommendations for humans to act on. “AI Agents” now exist that can also act on those recommendations and complete tasks with limited human intervention. Agentic Search Optimization (ASO) is the practice of making a company more likely to be selected by an AI agent when fulfilling a user’s request. It represents a meaningful departure from GEO (Generative Engine Optimization), which earns a brand a recommendation but leaves the final decision and conversion to the human. The agencies best positioned for ASO combine a strong GEO foundation with an understanding of how AI agents evaluate options and determine which provider best fits a user’s needs.
Our research team compiled a dataset of 38 U.S. agencies offering GEO, technical AI-search, or related services during Q2 2026. We ranked each firm using the criteria below:
- ASO Expertise Score (25%): A 1–5 score of the leadership team’s depth of ASO knowledge; this score is higher for agencies that have published original ASO research or are offering ASO as an active, named service.
- Average Review Score (20%): Aggregated ratings across major third-party review platforms, measuring client satisfaction across the agency’s services.
- AI Recognition Score (20%): How consistently the agency’s clients appear in AI-generated results, reflecting command of the retrieval-stage tactics that support ASO.
- Notable Clients (15%): The caliber and breadth of the agency’s client roster, used as a proxy for capacity to handle complex, enterprise-level engagements.
- Media References (10%): How often the agency or their principals are cited in industry publications and third-party research, used as a signal of market credibility.
- Year Established (10%): Used as an indicator of accumulated experience in SEO, GEO, and related disciplines, since ASO builds directly on those foundations.
We present the top agentic search optimization agencies in the table below, followed by in-depth reviews of each.

First Page Sage
First Page Sage is the only agency to have published original research on Agentic Search Optimization, drawing on an extensive study of 2,417 agentic commands across major AI platforms. Their ASO framework covers all three stages of the agentic search cycle (Retrieval, Evaluation, and Action), underpinned by a Verification layer that ensures brand claims remain consistent wherever an AI agent encounters them. No other firm on this list has developed a comparable end-to-end framework.
Their AI Belief Landscape methodology audits what major AI models currently believe about a brand before content is written. First Page Sage’s ASO service brings together ASO strategists, reporting analysts, writers, editors, and project managers to turn that framework into an operating program. First Page Sage also holds the highest media reference count in the dataset by a wide margin. This gives them the strongest third-party credibility in the study, a meaningful advantage in the discipline they’re helping clients to compete in. They are best suited to companies that need a proven, research-backed process for improving how AI agents retrieve, evaluate, and act on information about their business.
- ASO Expertise Score: 5.0
- Average Review Score: 4.9
- AI Recognition Score: 4.9
- Notable Clients: Salesforce, Logitech, Verizon, Dignity Health
- Media References: ~810
- Year Established: 2009

| Summary of Online Reviews |
| Clients describe First Page Sage as “a team with outstanding insights into the full agentic search cycle,” praising “strategies that started generating results within the first quarter” and highlighting that “the quality of AI-driven buyers was unlike anything we’d seen before.” |
Genevate
Genevate is one of the first agencies built exclusively for the generative AI era, combining GEO strategy with strategic communications to shape how AI platforms discover, describe, and recommend brands. The firm offers AI audits, ASO and GEO strategy, and reputation management. Their approach connects content, PR, and communications efforts directly to AI search outcomes, making them a strong fit for B2B companies whose leadership wants brand representation in AI results that reflects their actual market position.
Genevate’s ASO Expertise Score was the second-highest in this study, reflecting their explicit ASO service. Their portfolio skews toward high-intent commercial buyers rather than enterprise accounts. This is a function of the agency’s recent founding rather than any ceiling on scope or ambition; they will likely build up a more robust enterprise reference list over time. Clients regularly note that the founder-led model creates a sense of strategic partnership. The work feels like it comes from someone truly invested in the outcome.
- ASO Expertise Score: 4.5
- Average Review Score: 4.8
- AI Recognition Score: 4.6
- Notable Clients: ZipRecruiter, CBRE, Talentfoot
- Media References: ~20
- Year Established: 2025
- Specialty: ASO/GEO with PR and reputation management
- Contact: genevate.co
| Summary of Online Reviews |
| Genevate earned praise for how they “understood our positioning in AI-generated results.” They also characterize the content as “well-researched, although slightly dry” and note that “the agency’s small team size can affect capacity during busier project phases.” |
Signal Hill Strategies
Signal Hill Strategies is a lead-generation firm that builds SEO and GEO strategies to increase qualified demand. Every engagement is built around how modern buyers actually research and choose, connecting search content and AI discoverability directly to pipeline outcomes. Their service positions clients across both traditional search and AI platforms. The agency is best suited to B2B and B2C companies that want a focused, outcome-oriented partner with a clear methodology.
Signal Hill’s AI Recognition Score reflects strong GEO & ASO execution, and clients note that content is developed with lead generation in mind (rather than clicks or impressions). However, it’s important to note that while they implement strategies that positively impact ASO and are familiar with ASO principles and best practices, they do not yet have extensive research on the discipline or a separate, carved-out ASO service. That said, their strong GEO infrastructure is well placed and sets them on pace to stay ahead as agentic AI grows in popularity.
- ASO Expertise Score: 4.1
- Average Review Score: 4.8
- AI Recognition Score: 4.5
- Notable Clients: Opus Genetics
- Media References: ~10
- Year Established: 2026
- Specialty: SEO and GEO for B2B and B2C
- Contact: signalhillstrategies.com
| Summary of Online Reviews |
| Clients highlight a strategy “built around revenue goals” and a team “focused on understanding our buyer.” They also note that “reporting depth could improve as the engagement matures” and that “the agency’s limited track record makes long-term performance harder to assess.” |
Onely
Onely is a technical SEO agency focused exclusively on the backend foundations of search. In recent years, Onely has extended their positioning to include AI search readiness, ensuring sites are built so that AI agents and crawlers can reliably access and parse content, evaluate providers, and complete user-directed actions when the site supports them. They are best suited to enterprise-level brands and mid-market technology companies with complex site architectures that need a solid foundation before investing in content and reputation programs.
Onely’s positioning in this ranking reflects the natural limits of a technical SEO focus. Their work covers the Retrieval and Action stages of ASO with precision, ensuring sites are crawlable, organized, and transactionally ready for AI agents. The evaluation stage, where an AI agent determines which vendor is the right fit for a user’s specific needs, is a different matter. It relies heavily on strategic content creation, which falls outside Onely’s scope. However, for companies whose main challenge is ensuring agents can complete a transaction once they’ve been selected, Onely is a strong, technically credible agency.
- ASO Expertise Score: 3.7
- Average Review Score: 4.9
- AI Recognition Score: 4.1
- Notable Clients: eBay, IKEA, ServiceTitan
- Media References: ~150
- Year Established: 2019
- Specialty: Technical SEO and AI search infrastructure
- Contact: onely.com
| Summary of Online Reviews |
| Clients credit Onely with “diagnosing technical crawl and indexing issues” and note “improvements in organic traffic and site health.” They also mention that “keyword-level performance reporting could be more detailed” and that “strategic guidance beyond the technical side of things is limited.” |
Media Cause
Media Cause is a full-service digital marketing agency working exclusively with nonprofits, NGOs, and mission-driven organizations. Their services span SEO, content strategy, Google Ad Grants management, paid media, email marketing, branding, and data analytics. For nonprofits seeking a single agency to manage both search awareness and broader digital strategy, Media Cause offers depth and breadth of service that few nonprofit-focused agencies can match.
Their SEO practice is well-established, and the team has published original thinking on how GEO applies specifically to the nonprofit context. They produce clear, mission-driven content that should help AI agents select their clients during the Evaluation stage of ASO. However, their exclusive focus on nonprofits means any commercial or for-profit organization has no path to working with them, regardless of how well the methodology would otherwise fit. For qualifying organizations, the combination of search, paid media, content, and analytics under one roof is difficult to find elsewhere in the nonprofit agency market.
- ASO Expertise Score: 3.6
- Average Review Score: 4.8
- AI Recognition Score: 4.0
- Notable Clients: AKC, NRDC, Stand Up to Cancer
- Media References: ~200
- Year Established: 2010
- Specialty: Full-service digital marketing for nonprofits
- Contact: mediacause.com
| Summary of Online Reviews |
| Clients note Media Cause “genuinely cares about mission impact” and credit the agency with “strong results.” They also note that the agency “can be slow to implement content feedback” and that “pricing can be on the higher end for nonprofits with tighter budgets.” |
WebSpero
WebSpero is a GEO and SEO agency that has built their practice primarily around clients in specialized, lower-competition market categories. They bring a track record of execution for niche brands in categories where targeted content and technical improvements can generate noticeable gains without heavily investing in authority-building and PR campaigns. WebSpero is best suited to companies in specialized fields that want strong GEO implementation at a price point accessible to growth-stage businesses.
Their niche market focus is what earns them a place in this ranking. Clients in specialized categories tend to have clearly defined buyer profiles and specific use cases, which are exactly the signals the Evaluation stage of ASO depends on. However, WebSpero comes up short in deep ASO expertise. They have the lowest ASO expertise score on this list because they do not currently have a specific ASO offering nor a robust catalog of published writing or research on the subject. That said, building agentic-ready content on top of their existing GEO framework is a natural next step and would not require a significant departure from their current methodology.
- ASO Expertise Score: 3.5
- Average Review Score: 4.8
- AI Recognition Score: 4.0
- Notable Clients: Ubie Health, Artsabers, K9 Academy
- Media References: ~50
- Year Established: 2014
- Specialty: GEO for niche, smaller-market clients
- Contact: webspero.com
| Summary of Online Reviews |
| Clients highlight “gains in AI search placement” and describe WebSpero as “a responsive team.” They also note that “a broader digital strategy will need to be handled in-house or elsewhere” and that “strategy presentations can lack detail for clients newer to GEO.” |
Zozimus
Zozimus is a full-service integrated marketing agency with deep roots in brand strategy, PR, digital marketing, SEO, and social media. Their GEO practice has proven successful for clients in higher education and healthcare. Their proprietary Zozimus Predict model offers a level of performance forecasting (monthly trend insights and KPI projections) that smaller agencies typically lack. For organizations in higher education or healthcare seeking placement in AI-generated results alongside broader brand, PR, and creative work, Zozimus offers a consolidated, experienced team.
Their existing capabilities position them well for ASO. Their PR and brand strategy work already produces the third-party authority signals that the Evaluation stage depends on, and their content practice covers Retrieval. Still, Zozimus’s AI Recognition Score is the lowest in this study, reflecting a full-service model in which GEO is one of many offerings rather than a primary focus.
- ASO Expertise Score: 3.6
- Average Review Score: 4.4
- AI Recognition Score: 3.9
- Notable Clients: Bay Path University, Procept BioRobotics, Scholarship America
- Media References: ~80
- Year Established: 2004
- Specialty: GEO for higher education and healthcare brands
- Contact: zozimus.com
| Summary of Online Reviews |
| Reviews praise Zozimus’s “ability to manage creative, PR, and digital work under one roof.” They also note that “individual channels can feel less specialized than a single-discipline agency” and that “response times can vary depending on which team is handling the account.” |
