First findings from the Radar Brand Index. 50 named brands audited live with Radar. Stripe and BetterUp lead at 88/100. Hims and Hers hit 4/100. Three brands are completely invisible to AI. Here is what the data says.
Comparison Guide
AI search engines like ChatGPT, Perplexity, Claude, and Gemini now answer questions that used to go to Google. The agencies on this page help brands get cited in those answers through Generative Engine Optimization (GEO), Answer Engine Optimization (AEO), structured data, and entity authority building.

This is not a paid directory. Agencies were selected based on their public presence in AI search optimization, published methodology, tooling capabilities, and relevance to brands looking for AI visibility services in 2026. We included a mix of dedicated GEO/AEO specialists and established digital marketing agencies that are adapting their SEO practice for AI search.
Pixelmojo is included because we are an AI visibility agency and this comparison would be incomplete without us. We have tried to present every agency fairly, including their genuine strengths relative to our own.
An AI visibility agency optimizes your brand to be cited and recommended by AI search engines like ChatGPT, Claude, Perplexity, and Gemini. This includes Generative Engine Optimization (GEO), Answer Engine Optimization (AEO), structured data implementation, llms.txt creation, entity authority building, and citation monitoring. The goal is to make your brand appear when people ask AI models questions relevant to your category.
A GEO (Generative Engine Optimization) agency optimizes content for AI-generated answers and recommendations. An SEO agency optimizes for Google and Bing search rankings. GEO focuses on entity authority, structured data, llms.txt, extractable content (tables, FAQs), and citation signals. SEO focuses on keywords, backlinks, and page authority. Some agencies offer both, but the methodologies are different. A GEO agency understands how LLMs select sources for recommendations, not just how search engines rank pages.
Consider these factors: (1) Do they have their own GEO/AEO tools or are they reselling third-party dashboards? Agencies that build their own tools understand the problem more deeply. (2) Have they published methodology or thought leadership on AI search? (3) Do they practice what they preach on their own site? Check their llms.txt, structured data, and whether AI engines cite them. (4) Do they monitor citations across multiple AI providers, or just track Google rankings? (5) What is their pricing model, and does the sprint/retainer structure match your needs?
Yes. Key metrics include: share of voice (how often your brand appears in AI-generated recommendations for category prompts), citation count (how many AI providers mention your brand by name), source influence (which of your pages are being used as sources), hallucination rate (how often AI states incorrect facts about your brand), and sentiment (whether AI descriptions of your brand are accurate and positive). Tools like Radar by Pixelmojo measure all of these across ChatGPT, Claude, Perplexity, and Gemini.
Technical fixes like robots.txt configuration and llms.txt creation can take effect within days. Structured data and schema improvements typically influence AI citations over 2-4 weeks. Full entity authority building and content optimization usually show measurable results in 6-8 weeks. The timeline depends on your starting position: brands with existing content authority see faster results than those starting from zero.
GEO is not replacing SEO. It is an additional channel that is growing in importance as more people use AI search engines for discovery. Google still drives the majority of search traffic, and traditional SEO remains essential. However, AI search engines are capturing an increasing share of commercial and informational queries. Brands that invest in both SEO and GEO will have the broadest discovery surface.
