SEO vs AEO vs GEO: what's the difference?
Why you shouldn't pick just one
Treating SEO, AEO, and GEO as separate projects usually creates duplicate work. A page with a solid technical foundation, a clear answer-first structure, and accurate structured data is doing the groundwork for all three at once.
How I approach all three together
On this site: structured data connects services, industries, regions, and case studies into one consistent entity graph; service and industry pages open with a direct answer before the detail; and a public llms.txt file lists the site's key pages in plain language for AI crawlers that support it. None of this guarantees a specific outcome. It's the same honest groundwork applied consistently.
How do SEO, AEO and GEO differ in practice?
SEO is measured in rankings and clicks from search results, so the work centres on crawlability, relevance and links. AEO is measured in whether an assistant gives your page's answer, so the work centres on answer-first structure and clear, self-contained facts. GEO is measured in whether generative summaries cite or recommend your business, so the work centres on entity clarity, evidence and mentions across other sources. The disciplines share most of their foundations and differ mainly in what success looks like.
A practical order of work for small businesses
Start with technical SEO: fast pages, a clean sitemap, correct canonicals and valid structured data. Next, rewrite key service pages so each opens with a direct answer and states real facts such as prices, timeframes and areas served. Then make the business entity consistent everywhere it appears online, including profiles, directories and schema. Finally, earn mentions and links from relevant third parties over time. Each step makes the next more effective, and the first two can usually be done within weeks.
How to measure each one
For SEO, use Google Search Console for impressions, clicks, average position and indexing, plus Bing Webmaster Tools. For AEO and GEO there is no complete dashboard yet, so test manually: ask the questions your customers ask in ChatGPT, Perplexity, Gemini and Copilot, check whether AI Overviews appear for your key searches, and record which sources are cited. Analytics can also show visits referred by AI tools. Track these monthly, since AI answers change more often than search rankings.
Does AI search mean SEO no longer matters?
No. AI search features and assistants still retrieve most of their information from the web, and pages that are crawlable, fast, clearly structured and trusted by other sites are the ones they find and cite. What changes is that some questions are answered without a click, so visibility now includes being the cited source, not just the top blue link. Strong SEO remains the base layer; AEO and GEO make sure that visibility carries over into AI-generated answers.
Signs your SEO, AEO and GEO are working
In Search Console, impressions and the number of queries in the top ten rise steadily, and more pages move into the indexed report. In AI assistants, your business starts to appear, with consistent facts, when you ask the questions customers ask, and your pages show up among the cited sources. In analytics, visits from search and from AI tools grow and, most importantly, so do enquiries from those visits. Track all three monthly rather than reacting to day-to-day changes.

Frequently asked questions
Which one should a small business prioritize first?
SEO fundamentals first: technical health and on-page clarity. AEO and GEO layer naturally on top of that foundation.
Can a page rank well in Google but never get cited by AI tools?
Yes. Ranking and AI citation use different retrieval and selection logic, so strong SEO doesn't automatically transfer to AEO/GEO visibility.
Will this guarantee our business shows up in ChatGPT or AI Overviews?
No. No legitimate practice can guarantee that. This groundwork can improve machine readability and increase the likelihood of being surfaced, but it is not a guarantee.
Do I need separate content for SEO, AEO and GEO?
No. One well-structured page that answers the question directly, states specific facts and sits on a technically sound site serves all three.
