What these guides cover.
Search now happens in two places: the familiar list of links, and the answers that ChatGPT, Gemini, Perplexity and Google's AI Overviews write. The second draws heavily on the first, but it rewards some things more: content a crawler can read without JavaScript, business facts stated plainly and consistently, and mentions on sources the assistants already trust.
These guides explain what is known about how assistants choose their sources, how SEO, AEO and GEO differ, and the technical blockers that keep a website out of AI answers altogether.
