What Is GEO? Optimizing for AI Search Engines

For a while now, people have started asking ChatGPT or Perplexity the questions they'd otherwise type into Google. This shift is changing what it means for a website to be "visible", and that's what GEO (Generative Engine Optimization) is about.

What Changed From SEO to GEO?

Classic SEO aims to get a page ranked high in search results; the user clicks the result and visits the site. GEO works differently: the AI summarizes information from multiple sources in its own words and presents it directly as an answer. The user often doesn't click through to any site, they just see which source (if any) the AI cited.

Can AI Bots Actually See Your Site?

The first requirement here is simple but often overlooked: AI bots (GPTBot, ClaudeBot, PerplexityBot) need to actually be able to reach your site. Some hosting providers' security layers (ModSecurity, for instance) can block these bots without you realizing it, even when robots.txt allows them. So the first check should always be accessibility.

How Is Content Prepared Differently for AI?

While keyword density mattered in traditional SEO, clear, directly-answering sentences matter more for GEO. A page's first few sentences should be able to summarize its topic on their own. Structured data (like JSON-LD) also helps AI 'understand' content correctly, but adding a fake author name or a fabricated rating does the opposite, it damages trust.

Does This Actually Matter?

Short answer: increasingly so. Given how many people now ask questions directly to an AI assistant, a brand being invisible or misrepresented is a real missed opportunity. But there's no need to panic and rewrite everything around GEO either, basic accessibility and clear, honest content usually make the biggest difference.

How to Check Access in Practice

Seeing that robots.txt allows AI bots is a first step, but it isn't enough. The real question is whether their requests actually reach your server. A few ways to find out:

  • Search your hosting panel's access logs for user agent names like GPTBot, ClaudeBot, or PerplexityBot. If there are no entries, or they all return 403 errors, something may be blocking them.
  • If you use a firewall or CDN, check its bot management settings to see whether these bots are blocked by default.
  • If you're comfortable with technical tools, send a request to your site using one of these bot names and look at the response code.
  • If the block is on the hosting side, asking your provider's support team which rule is stopping the request is usually the quickest fix.

What Citable Content Looks Like

When an AI assembles an answer, it tends to use sentences that respond to a question briefly and make sense on their own. If a paragraph only makes sense after reading the three before it, it's hard to quote. Some approaches that work in practice: phrase a heading as a question and answer it in the very first sentence below, define a term in one sentence before using it, and present comparisons as lists or tables instead of loose paragraphs. Stating clearly who runs the page and when it was last updated is another trust signal. An accounting firm's page titled 'How do I register as a sole trader?' that sums up the process in two sentences, then lists the steps, is useful to readers and AI alike.

Why Results Are Hard to Measure

With classic SEO you can track rankings and clicks in tools like Search Console. GEO has no report that clear. People may read the answer and never visit your site, so your influence may not show up in traffic numbers at all. Visits from some AI services can appear as referrers in your analytics, so referral reports offer a partial picture. Beyond that, a simple tracking method is to ask a few common questions from your field to different assistants every so often, and note whether your brand comes up and how it's described.

Common Mistakes

  • Putting key information only inside an image or a PDF, instead of as text on the page itself.
  • Loading content only through JavaScript. Some bots don't run pages like a browser and may see an empty page.
  • Giving conflicting answers to the same question on different pages of the site.
  • Including details in structured data that don't appear on the page or aren't true.

Closing Thought

GEO doesn't replace good SEO, it's a layer on top of it. Make sure bots can reach your site, write pages that answer questions plainly, and check now and then how you're being described. That's a solid enough plan to start with.
