FAQ

Questions about this ranking.

What does an AI SEO agency do?

Typical work covers technical fixes, content structured for citation, entity building and tracking how often AI platforms mention the brand.

How did you choose these agencies?

The criteria are listed above the ranking, and the evidence behind each entry is stated in its description.

What should I ask an AI SEO agency before hiring?

Ask which prompts they will track, which AI engines they cover, what they change on your site and off it, and how they report citations. Ask for examples from businesses like yours.

What is the difference between GEO, AEO and AI SEO?

The terms overlap. GEO (generative engine optimization) and AEO (answer engine optimization) both aim to get a brand cited in AI answers. AI SEO is the broader label for adapting search work to AI platforms. Agencies use them differently.

How do I choose the best AI SEO agency?

Match the agency to your need. Look for named clients similar to your business, a specific AI-focused service rather than a generic SEO page, and a clear way to measure AI citations. Ask each to show past work before signing.
