It is also called **GEO** (Generative Engine Optimization) or **AEO** (Answer Engine Optimization). The goal is narrow and honest: make your content technically legible to the systems that increasingly answer questions on your behalf. It is not a trick to force a citation, and no one can guarantee one. What you *can* control is whether a model can fetch your page, parse your content, and find a clean, unambiguous answer when it looks. That is what AI Search Optimization measures and fixes. ## How it differs from classic SEO Classic SEO optimizes for a ranked list of blue links: keywords, backlinks, and click-through. AI search engines do something different: they read pages, extract claims, and synthesize an answer, often without sending a click at all. That shifts what matters: - **Machine-readability over keyword density.** The question is whether a crawler can extract a clean answer, not whether you repeated a phrase enough times. - **Server-rendered content over client-only rendering.** Many AI crawlers don't execute JavaScript. If your content only appears after hydration, they may see an empty page. - **Structured, unambiguous answers over prose padding.** Definitions, FAQs, and clearly-scoped headings give a model something concrete to quote. - **Citability over ranking.** There's no position 1. There's only whether your page is clear and trustworthy enough to be used in an answer. The two disciplines overlap (clean HTML and good metadata help both), but the bar for AI search is *legibility to a machine that reads, not just indexes.* ## What actually moves the needle In practice, the highest-leverage work falls into a handful of categories. These are the same seven that GEO Repair's checkup scores: 1. **Rendering**: your primary content is present in the server-rendered HTML, not locked behind client-side JavaScript. 2. **Structured data**: valid JSON-LD that describes what the page is (an article, an organization, an FAQ). 3. **Metadata**: accurate titles, descriptions, canonical URLs, and Open Graph tags. 4. **Crawl surface**: a working `robots.txt`, an XML sitemap, and crawl rules that don't accidentally block AI user-agents. 5. **Semantics**: one `

`, a sensible heading order, and real landmarks instead of a soup of `
`s. 6. **Content**: clear, self-contained answers a model can lift without guessing context. 7. **Answerability**: explicit definitions and question-shaped headings that map to how people actually ask. None of these are exotic. Most are the kind of technical hygiene a good engineering team already values; they just rarely get prioritized until something depends on them. ## An honest note on outcomes We'll say this plainly because the space is full of people who won't: **improving readiness does not guarantee traffic, rankings, or AI citations.** Whether a model cites you depends on factors no vendor controls. What a checkup *can* tell you is whether your site is technically ready to be read and quoted, and a fix can close the gaps that would otherwise rule you out before the question is even asked. That's the whole game: measure readiness, fix what's fixable, and stop leaving easy points on the table. ## Where to start Run a readiness checkup against your most important page. You'll get a score across all seven categories, the evidence behind each check, and a clear list of what's fixable. From there, the work is concrete, and most of it is the kind of thing that makes your site better for human readers too. --- _Markdown copy of [What is AI Search Optimization (GEO/AEO)?](https://geo.repair/blog/what-is-ai-search-optimization) — a faithful, machine-readable version of the page. © GEO Repair._
