No. 10 / SEO vs AEO
SEO / AEO / Comparison
One gets you ranked. The other gets you cited.
SEO (search engine optimisation) gets you found in search results. AEO (answer engine optimisation) makes you the answer AI assistants give. They are two halves of one visibility strategy: different surfaces, different work, same goal. Here is where they overlap, where they diverge, and which to invest in first.
Section 01
What does SEO actually do?
SEO makes your website appear in traditional search results. It covers technical health, keyword research, on-page content, backlink authority, and crawlability. When someone types a query into Google and scrolls through the list of results, SEO is the work that determines whether your page appears and how high it sits. For most of the past two decades, it was the only game in town: if you wanted organic traffic, you optimised for the ranking algorithm, earned links, and let the results compound.
- Technical SEO: site speed, crawlability, structured data, indexation.
- On-page SEO: keyword targeting, heading structure, content depth.
- Off-page SEO: backlinks, brand mentions, domain authority.
- Local SEO: Google Business Profile, local citations, review signals.
Section 02
What does AEO do that SEO cannot?
AEO makes your content appear inside the answer itself. When a user asks ChatGPT a question, queries Perplexity, or triggers a Google AI Overview, the engine does not return a list of links. It returns a synthesised answer, sometimes with citations, sometimes without. Answer engine optimisation is the work that makes your business the source the engine pulls from. It requires a different kind of authority: entity clarity, structured data, citation-ready formatting, and content that answers the question in a shape the model can extract.
- Entity authority: consistent identity across the web so models resolve you correctly.
- Schema markup: structured data that machines parse without ambiguity.
- Answer-first content: paragraphs shaped for extraction, not just readability.
- Citation signals: formatting, sourcing, and trust signals that models reward.
Section 03
How do SEO and AEO compare side by side?
The fastest way to see the difference is dimension by dimension. Same foundations, different finish line.

Rankings, impressions, clicks.
Citations, mentions, and answer share across AI engines.
Section 04
Where do they overlap and reinforce each other?
They share most of their foundation. High-quality content, strong domain authority, clean technical infrastructure, and well-structured pages benefit both. A site that ranks well in traditional search already carries many of the trust signals AI engines use when selecting sources. The difference is the final mile. SEO stops at ranking. AEO extends the work to ensure that when the engine synthesises an answer, your content is the one it draws from. Backlinks help both. Schema helps AEO more. Keyword targeting helps SEO more. Entity consistency helps AEO enormously and SEO moderately.
Section 05
Do you need both, running in parallel?
Yes, for most businesses. Traditional search still drives substantial organic traffic, and for many queries it remains the main path to your site. But for a growing share of questions, the user never reaches the traditional results at all. If you only do SEO, you are invisible in the answer layer. If you only do AEO, you give up the compounding traffic that rankings provide. Treat them as a single, integrated visibility strategy: build the technical foundation once, optimise content for both surfaces, measure both outcomes. The wider umbrella over all of this is generative engine optimisation (GEO), and our AI search optimisation service runs all three together: the agent proposes the fixes, a senior SEO approves every change, and we check the live page after each one ships.
Common questions
Frequently asked.
Q.01What is the difference between SEO and AEO?
SEO (search engine optimisation) gets you found in search results: it earns a position in a list that people click through. AEO (answer engine optimisation) makes you the answer AI assistants give, whether that is an AI Overview, a featured snippet, or a ChatGPT recommendation. SEO targets clicks. AEO targets the answer slot. Both matter for modern visibility.
Q.02Is SEO dead?
No. Traditional search still drives substantial organic traffic, and the foundations SEO builds, technical health, quality content, and authority, are exactly what AI engines look for when choosing sources. SEO is not dying. It is being extended, and AEO is the extension.
Q.03Is AEO replacing SEO?
No. AEO is an additional layer on top of SEO. Traditional results still drive most organic traffic, while AEO addresses the growing share of queries where the user receives a generated answer instead of, or before, the standard results page. You need both.
Q.04Is AEO part of SEO?
It is best understood as an evolution and extension of SEO rather than a separate silo. AEO builds on SEO foundations like content quality, structured data, and domain authority, then adds work specific to AI answers: question-shaped content, FAQ schema, entity authority, and formats a model can extract.
Q.05Can I do AEO without doing SEO first?
In theory, yes. In practice, most AEO signals build on the same foundation SEO creates: domain authority, quality content, clean technical infrastructure, and trust signals. Doing AEO without any SEO foundation is like trying to build the second floor without the first.
Q.06Which should I invest in first if I have a limited budget?
Start with SEO if you have no search presence at all, because it builds the authority and technical health everything else depends on. If your SEO base is already solid, layer AEO on top to capture the growing share of questions answered by AI. We run both together because they reinforce each other.
