THE BEST AI SEARCH VISIBILITY (GEO) AGENCIES IN 2026

The best AI search visibility agencies in 2026 are Anvil Digital, iPullRank, First Page Sage, Siege Media, Omniscient Digital, daydream, Directive, and, for teams that want software instead of a service, Profound. Each earns its place differently: iPullRank for enterprise-grade technical depth, First Page Sage for thought leadership content, Siege Media for digital PR and data journalism, Omniscient Digital and daydream for B2B SaaS content engines, Directive for B2B performance marketing, Profound for enterprise measurement software, and Anvil for measurement-first Share of Model work with B2B mid-market companies and medical practices. The market is young: the discipline is barely two years old, ranking pages like this one capture roughly 74% of AI citations, and citation overlap between AI platforms is only about 11%, so the right partner depends on which engines and which buyers matter to you. Below: how we built this list, what each firm does best, and what these engagements cost.

HOW WE BUILT THIS LIST

Full disclosure first: Anvil Digital wrote this list and appears on it. We put ourselves where we honestly believe we fit, and we are explicit below about who should NOT hire us. For everyone else, we verified three things as of June 2026: the firm exists and actively sells GEO or AI search visibility work (not a rebranded SEO page), it publishes evidence of that work (research, case studies, named clients, or funding), and independent third-party lists or coverage corroborate the positioning. We did not score competitors with our own rubric, and nothing here is pay-to-play. No agency on this list paid to be included or was contacted before publication.

One framing stat for why this market exists at all. Sundar Pichai called Google AI Overviews:

"one of the most successful launches in Search in the past decade."

AI answers are now the front door of search, AI-referred visitors convert at 14.2% versus 2.8% for Google organic, and ChatGPT cites brands in only about 0.59% of responses versus roughly 13% for Perplexity. Getting recommended is a discipline now. These are the firms practicing it credibly.

1. ANVIL DIGITAL

One-line strength: measurement-first Share of Model methodology with evidence-based content restructuring.

That is us. Every engagement starts with a live Share of Model measurement: golden prompts derived from your own buyers' questions, run 3x per engine across ChatGPT, Perplexity, Claude, and Gemini with live web search, reported per engine, monthly. Recommendations trace to the Princeton GEO-bench findings and empirical citation data (the methodology is public), and retainer bonuses tie to Share of Model improvement, not activity. Best fit: B2B mid-market companies ($10M to $500M revenue) and medical practices, where we maintain a healthcare-specific scoring model. Not a fit: enterprises that need a 50-person team, or anyone who wants a self-serve dashboard. Founder-led, deliberately small, capacity-limited.

2. IPULLRANK

One-line strength: the most technically rigorous GEO practice in the market.

Mike King's firm built its AI search practice on what it calls relevance engineering: embeddings, query fan-out analysis, passage retrieval, and advanced schema, applied to enterprise sites. iPullRank publishes the AI Search Manual and some of the most cited original research in the field, and its client roster includes SAP, American Express, and HSBC. Best fit: enterprises and funded scale-ups with technically complex sites and in-house teams who want the engineering explained, not hand-waved.

3. FIRST PAGE SAGE

One-line strength: thought leadership content engineered for AI-era search, at scale.

First Page Sage was publishing GEO research and rankings earlier than almost anyone and has worked with Salesforce, Verizon, Dignity Health, and Logitech. Its model centers on high-substance thought leadership content written with genuine subject-matter expertise, which happens to be exactly the content profile AI engines cite. Best fit: larger B2B companies in complex verticals (SaaS, medtech, manufacturing) with the budget for a long-term content program.

4. SIEGE MEDIA

One-line strength: data journalism and digital PR that earns the third-party citations AI engines trust.

Siege Media reports over $148M in yearly client traffic value and rebuilt its practice around prompt and citation data, with proprietary tooling for entity-level opportunities and automated content refreshes. Its digital PR muscle matters because off-site consensus, not your own domain, drives most AI recommendations. Best fit: consumer, e-commerce, and fintech brands that need citations earned on other people's websites.

5. OMNISCIENT DIGITAL

One-line strength: full-funnel organic growth for B2B software, with GEO as a core service.

Founded by former HubSpot growth marketers Alex Birkett and David Ly Khim, Omniscient runs SEO, content, and GEO programs for B2B SaaS companies including Jasper, Order.co, and Smartling, with published results like $3.7M in attributed pipeline. Engagements start around $10,000 per month. Best fit: funded B2B software companies that want one partner for the whole organic channel.

6. DAYDREAM

One-line strength: AI-native agency model combining SEO agents with senior strategists.

daydream raised a $15M Series A in April 2026 (total funding $21M) to build what it calls an AI-native agency for SEO and AEO, pairing automated agents with human strategy and acquiring Positional for analytics tooling. The model is the bet: software-speed execution with agency accountability. Best fit: B2B SaaS companies comfortable with a tech-forward, automation-heavy operating style.

7. DIRECTIVE

One-line strength: GEO inside a B2B performance marketing system tied to pipeline.

Directive has run search marketing for B2B tech for over a decade and now sells GEO as part of an integrated demand program, with the explicit goal of getting client messaging into ChatGPT and Gemini answers. The differentiator is accountability to revenue metrics rather than visibility metrics alone. Best fit: B2B tech companies that want AI visibility folded into an existing paid-plus-organic demand engine.

8. PROFOUND (PLATFORM, NOT AGENCY)

One-line strength: the category-leading software for monitoring AI search visibility at enterprise scale.

Profound is not an agency, and including it here without saying so would be dishonest. It is the measurement platform: a $96M Series C at a $1B valuation in February 2026, more than 700 enterprise customers, and 10% of the Fortune 500, including Target, Walmart, and MongoDB. It tells you where you stand across ChatGPT, Gemini, Claude, and Perplexity; it does not restructure your content or earn your citations. Best fit: enterprises with in-house teams who need monitoring infrastructure and will do (or separately hire) the optimization work.

HOW TO CHOOSE BETWEEN THEM

• Demand a baseline before a proposal. Any credible firm measures how AI engines answer your buyers' questions before prescribing anything. Our version of that process is in the Share of Model measurement guide.
• Ask for per-engine reporting. With only ~11% citation overlap between platforms, a blended visibility number hides the diagnosis. The differences between engines are the whole strategy.
• Check the evidence base. Statistics in content lift AI visibility 30 to 41%; attributed quotes lift it 28 to 32%; Domain Authority correlates with citations at r=0.18. If a pitch leans on tactics the data has debunked (llms.txt as a driver, link volume, keyword density), keep walking.
• Match the firm to your size. Enterprise problems need iPullRank or Profound. A $50M manufacturer or a 10-physician practice needs a partner sized to move fast at that scale.

WHAT THESE ENGAGEMENTS COST IN 2026

Across the market: audits and strategy run $2,500 to $25,000, implementation projects $15,000 to $50,000 for mid-market (six figures at enterprise scope), agency retainers $5,000 to $15,000+ per month, and software platforms from $49 per month for entry-level tracking to enterprise contracts at Profound's tier.
