AEO vs SEO: how they differ, where they overlap and what to do first

What is the core difference in AEO vs SEO?

SEO is about position in a list; AEO is about inclusion in a paragraph. A classic search result rewards the page that best matches a query with a high slot and a click. An AI answer blends several sources into one reply, names a handful of brands and links a few pages, and the buyer may never scroll to the links.

That shift changes what success looks like. In SEO you track rankings, impressions and organic sessions. In AEO you track whether your brand appears in answers to the prompts your buyers use, how often your URLs are cited, how your company is described and how many visits arrive from chatgpt.com, perplexity.ai or copilot.microsoft.com. The work underneath overlaps heavily, but the scoreboard is different.

How do AEO, SEO and GEO compare side by side?

The three labels share most of their foundations and split mainly on target and measurement. The table below sets them out; GEO and AEO are often used as synonyms, so treat the GEO column as the content-focused slice of the same goal.

If you only remember one row, make it the measurement row. Teams that keep reporting only rank positions often miss that they have been dropped from, or added to, the answers their buyers read.

Is AEO just SEO, according to Google?

For Google's own AI features, largely yes. Google's AI optimization guide, updated in July 2026, says optimizing for generative AI search "is still SEO" and that no special files, markup or Markdown are needed, and it does not require breaking content into tiny pieces.

Google's AI features documentation adds that a page only needs to be indexed and eligible for a snippet to appear in AI Overviews or AI Mode, with no additional requirements. So for Google, technical SEO and helpful content remain the price of entry.

The picture widens outside Google. ChatGPT, Perplexity and Claude run their own crawlers, which robots.txt files and CDN settings often block by accident. They also pull heavily from forums, video and review platforms. That is the ground AEO covers that a Google-only SEO program can miss.

Does ranking in Google still get you cited in AI answers?

It helps, but less than many teams assume. Ahrefs found that 38% of AI Overview citations come from pages in the top 10, down from 76% a year earlier, so a top ranking is no longer a reliable ticket into the overview.

The engines appear to cast a wider net, partly because of query fan-out: Google's documentation explains that AI features may run several related searches across subtopics before showing supporting links. A page that answers one of those sub-questions directly can be cited even if it does not rank for the head term. That rewards specific, well-structured pages over broad ones that try to cover everything.

Do backlinks or brand mentions matter more for AEO?

Mentions appear to matter more. In an Ahrefs study of 75,000 brands, web mentions correlated 0.664 with AI Overview visibility, against 0.218 for backlinks.

Correlation is not proof of cause, but it matches what practitioners see: answer engines summarize what the web says about a brand, so being discussed on Reddit, reviewed on G2 or Capterra, covered in trade press and present on Wikipedia or Wikidata shapes how you are described. Backlinks still matter for SEO and for discovery. For AEO, the question becomes who talks about you, where and in what words. Google's guide warns against inauthentic mentions, so this is earned work, not a link scheme.

How does page structure differ for AEO and SEO?

AEO pages put the answer first and keep each section self-contained. SEO pages can rank with a long build-up; answer engines tend to lift a clear passage, so a buried answer is easy to skip.

In practice that means H2s phrased the way buyers ask, such as "How much does payroll software cost for 50 employees?", followed by one or two sentences that answer it without needing the paragraph before. Detail, caveats and examples follow underneath. FAQ blocks work for the same reason: each answer stands alone. Comparison pages and alternatives pages earn citations because buyers ask comparative questions and the engines need a source that lays out the trade-offs plainly.

Freshness signals matter more too. Visible last-updated dates, current pricing and dated original data give an engine a reason to prefer your page over an older summary. None of this conflicts with SEO. Google's guide simply says you do not need to chop content into tiny fragments, so the aim is clarity, not a page of disconnected snippets.

Which metrics change when you add AEO to SEO?

You keep your SEO metrics and add citation-focused ones. Clicks are not the whole story, because a brand can shape a buyer's shortlist inside an answer without a visit.

Seer Interactive reported that brands cited in an AI Overview earned 35% more organic clicks than those not cited, and Semrush estimated the average AI search visitor is worth 4.4 times an organic visitor. Both are good reasons to track AI traffic separately rather than burying it in referrals.

• Search Console generative AI performance report for impressions and clicks from Google's AI features.
• Bing Webmaster Tools AI Performance for Copilot citations, cited pages, grounding queries and citation share.
• GA4 referrals from chatgpt.com, perplexity.ai, copilot.microsoft.com and gemini.google.com, grouped as one channel.
• A fixed prompt set run monthly in each engine, recording which brands and URLs are cited.

Should you invest in AEO or SEO first?

Fix SEO foundations first, then layer AEO on top. If pages are not indexed, render only in JavaScript or block key crawlers, no amount of answer-first rewriting will help.

A sensible sequence looks like this: confirm Googlebot, Bingbot, OAI-SearchBot, PerplexityBot and Claude-SearchBot can reach your pages, and check Cloudflare's AI crawler settings and your server logs. Then restructure the pages that answer buyer questions so the answer sits in the first lines under a question-style heading. Then align your company facts across your site, Organization schema with sameAs links and the directories your industry uses. Finally, build genuine mentions and start a monthly prompt-set report. Most of that work also improves classic rankings, which is why the two budgets rarely compete as much as they seem to.

Can one team handle both AEO and SEO?

Yes, if the team adds a few skills. An in-house SEO team already owns crawlability, content and reporting; AEO asks them to also manage AI crawler rules, entity data, community and review presence, and prompt-based tracking.

Where we see gaps, they are usually in measurement and off-site work rather than in writing. Many SEO teams have never pulled AI referrals into their own GA4 channel or opened Bing's AI Performance report, and few have a routine for Reddit, YouTube or review-site presence. An outside AEO partner can set those up and hand them over, or run them as an ongoing program.
