GEO vs AEO vs SEO: what is different and what is not
By Hamza Rivera, updated
- SEO aims to rank pages in search results. AEO aims to be the direct answer. GEO aims to be cited in generated answers from AI tools.
- They share one foundation: crawlable, accurate, well-written pages from a business people trust.
- The names are partly marketing. Google's own guidance says there are no special requirements for its AI features beyond normal search fundamentals.
- Spend on the shared foundation first, then add the parts that differ.
Three acronyms are doing the rounds, and sellers use them as if they were three different products. They overlap more than they differ. This guide sorts out what each one means, what is real in the difference, and where to put effort if you have a small budget.
For the whole stack, see our GEO and AEO services.
SEO is getting your shop onto the high street. AEO is being the shop the person at the information desk points to. GEO is being one of the shops a guidebook writer decides to mention. The street, the desk and the guidebook all reward a shop that is open, honest and easy to find.
What each term means
| Term | Aims at | Verdict |
|---|---|---|
| SEO (search engine optimization) | Ranking pages in search results | The base layer |
| AEO (answer engine optimization) | Being the direct answer or featured result | SEO with answer-first writing |
| GEO (generative engine optimization) | Being cited in answers that AI tools write | SEO plus outside evidence and tracking |
Where they overlap
Almost everything. A page that cannot be crawled cannot rank, cannot be a featured answer and cannot be cited. A page with no clear subject does badly in all three. Google's documentation on its AI features in search says that the same fundamentals apply: pages need to be indexed and eligible to show with a snippet, and there are no extra technical requirements. If someone tells you that you need a secret file or special markup for AI, ask for the source.
Where they differ
- Format. AEO rewards a short, direct answer at the top of the page. SEO is happy with that too, but it does not require it.
- Evidence beyond your site. Generative tools often draw on third-party pages. GEO puts more weight on reviews, independent articles and consistent listings.
- Measurement. SEO has rank trackers and Search Console. AI answers vary from run to run, so GEO needs repeated sampling. See how to track AI visibility.
- Crawler access. AI tools use their own crawlers, which you can allow or block in robots.txt.
Which one should a small business start with?
Start with SEO fundamentals, because they feed the other two. Then write answer-first pages, which is cheap and helps everywhere. Then add outside evidence and tracking. Our own approach on generative engine optimization services follows that order.
A worked example
Take a dental clinic in a mid-sized city. The SEO job is a page for each treatment, a tidy Google Business Profile and fast pages. The AEO job is to open each treatment page with a two-sentence answer to the question patients ask, such as how long a crown takes. The GEO job is to check that reviews, the dental association listing and local press mention the same services and the same address, and then to ask ChatGPT the same ten questions each month to see whether the clinic is named. Three acronyms, one set of pages.
How to read a sales pitch
- If the pitch promises a guaranteed placement in AI answers, walk away.
- If it lists the same tasks as an ordinary SEO plan under a new name, you are paying for a label.
- If it includes sampling and reporting that you can read, it is probably real work.
Every few years the industry renames SEO. It is still the same plant, with a new tag in the pot.
Mistakes to avoid
- Dropping SEO work to chase GEO.
- Rewriting every page in one go and losing track of what changed.
- Trusting a single screenshot of one AI answer as proof.
Pick one page that matters, rewrite its opening as a direct answer, and watch what happens over a month. That small test teaches more than any acronym.
