AEO vs SEO: how they overlap and where they differ

You are probably here because a proposal, a vendor email or a colleague raised AEO and you need to decide: is it a separate thing, a replacement, or SEO under a new name? The definitions are covered elsewhere. This page is for the decision in front of you, how to avoid paying twice for the same work, and how to tell which of the two is actually underperforming for your business.

The short answer

Do not start two projects. Fix the shared foundation first, because neither works without it. If your search results are healthy and assistants still skip you, the gap is AEO work: answer pages, consistent facts and measurement. If your site is slow, unindexed or broken, start with SEO. Ask any provider what each deliverable is and how it will be reported.

The one-paragraph version

SEO is about earning visibility in search results. AEO and GEO are about being named inside an AI answer. They share most of their foundations, and they are measured differently. The comparison, including what Google says about the labels, is in AEO vs SEO vs GEO, and the terms themselves are in the glossary as answer engine optimization and generative engine optimization.

How to avoid paying twice for the same work

A common risk is AEO being sold as a separate project that turns out to be the same page edits as the SEO work, relabeled. Before agreeing to a scope, ask for each deliverable to be listed by name.

  • Technical fixes (indexing, speed, mobile layout): this belongs to SEO and helps both. It should be one line item, not two.
  • Page rewrites: if the same page is being improved for ranking and for quotability, that is one rewrite.
  • Answer pages for specific customer questions: this is the AEO-led work, and it should be written from real details about your business.
  • Fact consistency across profiles and listings: shared by both, and usually a one-off clean-up followed by a quick check each month.
  • Measurement: SEO in Search Console and analytics, AEO in a fixed monthly question test. Two reports, one source of truth for each.

Ten questions to ask any provider selling AEO

  1. 1What exactly will I receive each month? Ask for a list of deliverables, not a list of benefits.
  2. 2Which of those would also be in an SEO plan, and am I being charged for them once?
  3. 3How will you measure whether it worked, and how many times do you test each question?
  4. 4Which assistants will you test, and why those?
  5. 5Will you share the raw answers, not just a score?
  6. 6What do you do if an assistant says something wrong about us?
  7. 7Do you promise mentions or positions? If so, based on what evidence?
  8. 8Which pages will you change, and will I approve them before they go live?
  9. 9What do you need from us, and when?
  10. 10What happens to the work if we stop?

Any promise of a guaranteed position or mention in an assistant should end the conversation. Nobody outside the assistant companies can control it. The ownership and ending-a-plan terms for Webtec work are written in your proposal, so ask your project manager rather than relying on a summary here.

Reading your reports: which one is moving?

Keep two separate views so a good number in one is not mistaken for progress in the other. For search, use Search Console and your analytics: impressions, clicks and enquiries from organic search. For AEO, use the answer sheet from your monthly test, and read measuring AI visibility for how to run it without fooling yourself.

Do not expect them to move together. A page can rank well and still be skipped in an answer, and a page can be quoted without ranking first. When your monthly report shows one up and the other flat, that is information about where to spend the next hours, not a contradiction. If you cannot tell which number is which, read your monthly report is the place to start.

A worked example of splitting a modest effort

Example: Twenty hours a month

A B2B software firm has about 20 hours a month to spend. It puts 8 on technical fixes and content updates that help both channels. It puts 8 into writing and refining four answer pages for the questions prospects ask in sales calls. It puts 4 into the monthly assistant test and fixing profile inconsistencies. After three months it compares organic clicks in Search Console with how often it is named and which pages are cited, then rebalances. No share is fixed, because nobody knows the right split for every business, and the firm records the reason for each change.

When to ask us

If you are not sure which to prioritize, send a request through the support form. Include your site address, your top three customer questions, the proposal or email you are weighing (as a Google Drive or Dropbox link) and any current SEO or AEO reports. Say what you are trying to decide, such as "SEO only, AEO only or both." We will say plainly where attention is best spent and why. Pricing is on our pricing page, and SEO pricing explains what is included. Never send passwords.

Your project manager can answer questions about timing and scope. Plan terms are written in your proposal.

Questions people ask

My SEO agency says AEO is just SEO. Are they right?

Partly. Many foundations are shared, and a good SEO agency already does some of them. But some AEO work is different: answer pages built from real business details, fact consistency across third-party sites, and a repeated assistant test. Ask them to show where that work appears in their scope and how it is reported. If it does not, you have your answer.

Can I buy AEO without SEO?

You can, but it only works if your site is already crawlable, indexed and reasonably fast, because assistants cannot cite pages they cannot reach. If your basics are healthy, AEO alone can make sense. If you are unsure, ask us to check the foundation first, and we will say whether SEO work has to come first.

Should I rewrite my whole site for AI?

Usually no. Start with the three to five questions that matter most to your customers and make sure one page answers each, clearly and with real details. Rewrite more only if the first batch shows that it helps. A full rewrite on a hunch spends budget on pages nobody tested and can hurt pages that already rank.

What if my customers do not use ChatGPT?

Then your priority may stay with SEO and local accuracy, and you can revisit AEO later. Ask a handful of recent customers how they found you, and whether they used an assistant. Their answers matter more than any industry average. Even if few use assistants today, the shared foundation work is never wasted.

How do I know the AEO work is worth continuing?

Judge it over several months of the same question test, not one. Look for wrong facts shrinking, your own pages showing up among cited sources, and enquiries that mention an assistant. If none of these move after a few months, ask what changed and why. Do not accept a score with no raw answers behind it.
