The simplest distinction
SEO is about clicks from a results page. AEO is about being named in an answer. SEO ranks pages, and the goal is a top organic position a searcher clicks. AEO is measured inside an AI generated answer, and the goal is to be named in it, cited among its sources, or both. The click may still come, and some of the value lands before anyone clicks.
So the measurement differs first. SEO reports a position from 1 to 100 for each keyword in a location. AEO reports how often each assistant names or cites you across the questions you track. Both answer “am I visible?”, with a different unit of visibility.
Shared signals
Most of the fundamentals carry over. For its own AI features, Google says the best practices for SEO remain relevant, with no extra requirements. Work that helps SEO also helps AEO:
- Authority and topical depth. Google rewards them with rankings; assistants that search the web reward them with citations.
- Original, useful content. Well researched pages beat thin ones on both.
- Accurate structured data. Google asks that it match the visible text on the page, and its AI features need no special markup.
- Internal links and site structure. They help crawlers find and understand your pages, and Google lists findable internal links among the basics for its AI features.
- Technical health. Crawlability, speed and mobile rendering matter to both.
That overlap is why many teams run AEO and SEO as one program with two ways of measuring it.
Where the signals diverge
At the margin, assistants weigh some signals differently from Google’s organic ranking:
- Brand familiarity. Classic SEO leans on links. An assistant answering from memory can only use what was written about you before it was trained, in reviews, press and forums, whether or not those mentions link.
- Reference sites. An accurate entry on reference sites such as Wikipedia, where your business qualifies, helps people and models describe you correctly.
- Answer first formatting. Lead with the answer in a sentence or two, use headings phrased as questions, and put comparisons in tables. Clear structure makes a passage easy to quote, for a person or a model.
None of these reverses an SEO best practice. They add emphasis to the same foundation.
The measurement difference
SEO measurement is mature: a position from 1 to 100 for each keyword and location, checked daily or weekly, with click through curves to estimate traffic. AEO measurement is newer:
- Mention rate: the share of answers, across assistants and questions, that name your brand.
- Citations: whether your pages appear in an answer’s sources, and how high.
- Share of voice: your mentions against your competitors’ across the questions you track. See share of voice.
The same question can get a different answer from one run to the next, so asking a fixed set of questions on a regular schedule and watching the trend tells you more than a single screenshot.
Why teams measure both
Your analytics show how much traffic organic search and AI assistants each send you today. Measuring AEO now gives you a baseline, so you can see what moves as that mix changes in your category. Google reports clicks from its own AI Overviews and AI Mode inside Search Console’s search traffic.
The practical setup is one program: the same content, schema and technical work, reported two ways. Rank.ai tracks your Google rankings and asks ChatGPT, Claude and Gemini your buying questions every day, on the same login.
