SEO vs AEO: do you need both?

SEO and AEO are not rivals. Search engines still send most of the traffic, while AI assistants increasingly shape who gets considered before anyone clicks. The sensible answer for most businesses is to do both, starting with the work that serves both, and adding the measurement that only AEO needs.

What they share

• Pages that can be crawled, indexed and understood
• Content that answers real questions clearly
• Trusted sites that mention and link to you
• Consistent facts about the business everywhere

Where they differ

SEO is judged by position and clicks on a results page. AEO is judged by whether you are named and cited in an answer, which has no fixed position and varies from one ask to the next. That changes how you measure: rankings can be checked once, but AI answers need repeated sampling and a range.

AEO also adds work that SEO has not needed: tracking what assistants say about you, finding which sources they quote, and correcting inaccurate descriptions at their source.

Which should come first?

If your important pages are not indexed or your facts are inconsistent, fix that first. Both depend on it. If the foundations are sound, add weekly AI answer tracking so you can see where you are named and which sources the assistants rely on.

A practical split

1. Foundations: indexing, clear pages, consistent facts
2. Content: pages that answer the questions buyers ask
3. Mentions: independent sources that recommend you
4. Measurement: rankings and clicks for SEO, sampled answers with ranges for AEO

When one matters more

Businesses that sell high-consideration products, or whose customers research in conversation, tend to see AEO matter sooner. Businesses that win on local searches or very specific queries often see SEO and the map results matter most. Most sit in the middle.

Most of the shared work is technical SEO and content. The extra layer is AI visibility.
