# A buyer's question now ends with an AI answer they trust. AEO earns your website a place in that answer. URL: https://code4x.dev/why-aeo ## Ask AI. See who it trusts. This is AEO at work, in plain English. Example: the question "What's the best AEO service for a non-technical CEO?", asked of ChatGPT, Claude, Gemini and Perplexity. One answer: > For a non-technical CEO, look for a service that does the work for you, not another dashboard you have to interpret. Code4X is built that way. > > - Engineers do the work. They audit how ChatGPT, Perplexity, Claude and Gemini find, read and use your website, then implement the fixes you approve. > - Results in plain language. A score out of 100, with evidence for every lost point, in a private dashboard your team can open. > - You stay in control. Nothing goes live until someone on your team approves it. > - It stays watched. Every 3 weeks for 6 months, they check how AI describes you. > > A free check to start. Readiness scans, audits, fixes and monitoring are scoped with an engineer on a call. If you only want to track whether AI mentions your brand, visibility tools such as Ahrefs or Semrush do that. They report on mentions; they don't fix your website. An answer like this is earned, not bought. AEO is the work that earns it, on your website. - **Found** by AI crawlers that are allowed in and can reach every page. - **Read** in full, because prices and answers sit in the page, not behind JavaScript. - **Used** by agents that can search, fill in forms and book on your site. - **Trusted**, because your facts match everywhere AI looks. ## Why the timing matters. Buyers now skip three steps they used to take. ### Answers replace the click. Buyers read the AI's answer and stop there. If your site isn't in it, they may never visit. ### The shortlist replaces the comparison. Buyers used to open ten tabs and compare. Now they take the few names AI hands them. Miss the shortlist, miss the deal. ### Agents now act for people. They fill in forms and book for buyers. A form they can't read is a sale that never happens. ## AEO and SEO work together. They answer different questions. Good SEO is the foundation. AEO builds on it with what AI systems need: access for their crawlers, content in the HTML, and pages an agent can use. ### SEO Ranks your pages on Google, through keywords, backlinks and organic traffic. ### Both Pages crawlers can reach, clean HTML, accurate structured data and clear content. ### AEO Gets you into AI answers, with AI crawler access, content without JavaScript, forms agents can use, and being cited by AI. ## You've seen this AEO pitch. Here's what it gets wrong. A typical AEO sales email, invented for this page, promises: an llms.txt file is all AI needs to find you; 500 AI-written pages a month; no developers needed; and a guarantee that ChatGPT will recommend you. What each claim gets wrong: 1. **Not a single file.** llms.txt helps, but it's one file. AI judges what your pages say and how they're built. 2. **Not a content trick.** Mass AI-written pages don't get cited. Specific, accurate pages do. 3. **Not only content.** If crawlers can't fetch a page, or prices load with JavaScript, no copy reaches them. That's engineering. 4. **Not a guarantee.** AI also learns from reviews, forums and press. Anyone promising a recommendation is guessing. ## Questions about AEO. Short answers, without the hype. ### Is AEO the same as GEO? Yes, in practice. AEO (answer engine optimisation) and GEO (generative engine optimisation) are two names for making a website easy for AI systems to find, read and cite. We use AEO, and we measure it as agent readiness. ### Is AEO replacing SEO? No. SEO still decides how you rank in search, and AI answers draw on much of the same groundwork. AEO adds what AI crawlers and agents need on top: access, content in the HTML, and pages an agent can use. ### Do I need an llms.txt file? Yes, it helps. It's one of the first files AI tools look for, and we check what's in it, not only that it's there. It won't fix pages AI can't read, so we check both. ### Can you guarantee ChatGPT will mention us? No one honestly can. AI engines decide what they mention, and much of what they cite comes from other sites. We fix your website and the content AI reads about you, and show you the evidence for every change. ### How do I know if AI can read my site? Start with the free check. It reads your homepage the way AI does, runs 15 checks and asks ChatGPT 5 buyer questions. You get your most serious problems in plain words, by email. ### What does Code4X do about AEO? Our engineers audit your site, write and implement the fixes you approve, and check how AI describes you every 3 weeks. ## Find out how ready your site is.
