On Site AEO vs Off Site AEO

On-site AEO vs Off-site AEO: Are You Covering Both?

‍

Most businesses still think SEO when they should be thinking AEO.

Answer Engine Optimisation is the discipline of making sure AI tools like ChatGPT and Google's AI Overviews don't just find your site, they choose to quote it. That's a different game to ranking on page one. AI engines aren't sending someone to click through and decide for themselves. They're making the decision on your behalf, in the answer itself.

That decision happens in two places. Get both right and you're in the conversation. Miss one and you're invisible.

On-site AEO: what you control

‍

On-site AEO is everything within your own four walls. It's the groundwork that makes your content easy for an AI engine to lift straight into a response.

That means:

• Clean, logical site structure that's simple for engines to crawl and understand
• Content written to answer real questions directly, not buried three paragraphs deep
• Schema markup that spells out exactly what your content is and means
• Copy structured so a single paragraph can stand alone as a complete, quotable answer

If your site nails this, you become easy to quote. The engine can find the answer, understand it, and lift it without any extra work.

‍

Off-site AEO: what you influence

‍

Off-site AEO is everything happening away from your website that still shapes whether an AI engine trusts you enough to reference.

That includes:

• Brand mentions across other sites and publications
• Citations and backlinks from credible sources
• Reviews and third-party validation
• Consistent signals across the web that back up who you are and what you do

This is where AI engines build confidence. Being easy to quote isn't enough if nothing outside your site tells the engine you're worth quoting in the first place.

Why you need both

Nail the on-site work and you're easy to quote. Build the off-site signals and you're worth quoting. Do one without the other and you're leaving half the equation unanswered.

Most businesses are still putting all their effort into one side, usually on-site, because it feels more within their control. But AI engines are cross-referencing both before they decide who makes it into the answer.

If you're not sure which side of AEO your business is missing, that's exactly where we'd start.
