AEO vs SEO: what changes when AI answers

SEO and AEO look like the same job under a new name. They aim at two different moments: a page of results a person scans, and a single answer a machine speaks. The sections below cover what changes and what stays the same.

The core difference

SEO optimizes for a ranking. You want to be near the top of a results page, because the human doing the searching will scan a few links and click one. There is a second page, a third, a long tail of chances.

AEO optimizes to be the answer. When someone asks ChatGPT or Perplexity for the best option, they often get one recommendation, not ten links. Either your product is in that answer or it is invisible. There is no page two to fall back to.

What carries over from SEO

AEO builds on SEO, and the basics still count:

• Fast, crawlable pages.
• Clean, valid markup.
• Clear titles and descriptions that match real questions.
• Genuine, useful content rather than keyword filler.

If your SEO is a mess, your AEO will be too. Good SEO is where AEO starts.

What AEO adds

AEO cares about things classic SEO treated as optional:

• Machine-readable facts. Price, brand, GTIN and availability in structured data, not just visible on the page. Most product pages that AI assistants cite carry structured data; pages without it get read fragmentarily or skipped. (Which fields matter.)
• Answer-shaped writing. A direct answer up top that a model can lift cleanly, with the detail below it.
• Consistency a model can trust. Your data across the page, your feed and your other pages should agree. Contradictions make an assistant back off.
• Access for the right crawlers. Being cited depends on letting the retrieval crawlers read you, which is a different setting from the training crawlers.

The mindset shift

SEO asks "how do I rank for this query?". AEO asks "if an assistant answered this question out loud, would it name us, and could it read enough to be sure?". You are competing to be the sentence the assistant says.

The work overlaps enough that you are not starting over. Clean data and clear answers help both. Start with the complete guide to AEO, then check your store for the gaps: run the free check.
