How to evaluate a GEO agency in 2026
Generative Engine Optimization is still a young category. A useful comparison page should make evidence easier to inspect, not hide behind vague scores or unverifiable growth claims.
Start with evidence, not rankings
A good GEO agency should be able to show how it improves brand visibility in AI-generated answers. Look for public methodology, examples of entity work, technical SEO depth, content quality, digital PR capability, and measurement beyond a single prompt.
Useful signals
Clear explanation of how the agency measures AI visibility.
Evidence of technical SEO, schema, crawlability, and entity work.
Content strategy that creates original, citation-worthy material.
Digital PR or authority-building capability for third-party mentions.
Transparent limits around what can and cannot be guaranteed.
Red flags
Be careful with pages that show ratings, review counts, or percentage improvements without source links. AI search can cite a page because it is easy to parse, not because every number on that page has been independently verified.
A simple scoring model
Score each provider across five dimensions: technical readiness, entity authority, content quality, external citations, and measurement quality. This keeps the comparison explainable and gives buyers a reason to trust the shortlist.
