What is a GEO agency?

A GEO agency helps brands improve visibility in AI-generated answers from systems such as ChatGPT, Perplexity, Google AI Overviews, Claude, and Gemini.

How are these rankings scored?

Rankings use editorial criteria including public methodology, specialization, service fit, evidence quality, and verifiable company presence. Scores are not paid placements.

Should I choose a GEO agency or an AI SEO tool?

Choose an agency when you need strategy, implementation, and authority building. Choose a tool when your team can execute internally and needs monitoring or optimization workflows.

AI search is creating a new vendor category, but many pages blur paid placement, review claims, and performance numbers. This page keeps the list short and points readers to evidence wherever possible.

Scoring frame

The goal is to be useful to buyers and legible to search engines without inventing fake review counts or unverifiable growth claims.

Public methodology and service focus

Evidence links to company-owned or public pages

Fit for AI search, entity authority, and citation readiness

Clear limitations, best-fit customers, pros, and cons
