AI SEO

The everyday name for optimising a brand for AI answers, and the term most buyers search for. The trade calls the work GEO, and what decides whether the engines name and recommend the brand is its AI authority.

What it tells a buyer or a marketer

AI SEO is the everyday name for optimising a brand for the answers AI engines write, by analogy with search engine optimisation, and it is the term most buyers search for. The trade calls the same work generative engine optimisation (GEO), or answer engine optimisation (AEO). The term is useful because it is how many people search for help, and misleading if it suggests the work ends at a website.

The search half is real. An engine can only quote a site it can find, read, and trust, so crawlable pages, structured data, clear answers to buyer questions, and consistent facts all help. That work overlaps with SEO and helps search results as well as AI answers.

Where AI authority fits

People search for AI SEO. What decides the answer is AI authority: a company's search signals plus what trusted independent sources say about it. The engines weigh publications, reviews, rankings, comparison sites, directories, and the institutions that judge an industry, and the AI Authority Index™ finds that these independent sources decide who the engines recommend.

CRISP™ measures both halves on five factors, Consensus, Reputation, Influence, Source, and Presence, so a company can see whether its gap is in what it publishes or in what others publish about it.

What moves the answer

Fix the facts the engines repeat, make the site readable to them, answer the buyer questions where they name someone else, and win the sources they cite for the market. Then ask the same questions again, on the same engines, because the answers themselves are the only measure of whether the work changed anything.

Related terms

AI SEO is the everyday name for the work the trade calls GEO, and AI authority is what decides whether that work pays off. CRISP reads AI authority on five factors: Source reads a company's own site, and Influence reads what independent sources say about it. AI visibility, whether the engines name a company at all, is where both start.

CRISP measures AI authority, which includes the search signals AI SEO works on and adds what independent sources say about a company. It reads the answers the engines write, as well as the site behind them.

How is AI authority different from AI SEO?

AI SEO names the work. AI authority is what decides the answer: a company's own search signals plus what trusted independent sources say about it, which the engines weigh when they decide who to recommend.

They name the same job. Generative engine optimisation (GEO) and answer engine optimisation (AEO) are other names for it.
