The 75-point line: why your AEO score matters more than your SEO score now.

If you score below 75 on our Beacon rubric, you are close to invisible in AI-answer surfaces. Ranking #1 on Google does not save you. AI Overviews, ChatGPT browsing, Perplexity, and Claude pull from a different signal set than the classic blue-link index, and that set rewards machine-readable structure over backlinks and keyword density. Beacon is our AEO audit tool. We have run it against 50-plus companies. The pattern is consistent: a clean SEO setup and a failing AEO score live in the same site all the time. This article explains the rubric, why we drew the line at 75, and what to fix first.

AEO and SEO are not the same job

SEO optimizes for a ranking algorithm that crawls, indexes, and orders pages. AEO optimizes for a model that has to read your page, extract a fact, and decide whether to cite you inside an answer it generates. Those are different demands. Google's classic crawler is patient and renders JavaScript. The AI crawlers are not all the same animal. Beacon scores against four of them by name: GPTBot, ClaudeBot, PerplexityBot, and Google-Extended. Some fetch your raw HTML and stop. If your content only exists after the browser runs your JavaScript, those bots see an empty shell. Your page ranks. Your page is also unreadable to the thing writing the answer.

What the free scan actually checks

The Beacon free scan looks at four things. None of them require us to log into your site. All of them are things an AI crawler cares about before it will trust and quote you.

• Schema and structured data: whether your facts are marked up in a form a model can parse without guessing.
• Crawlability for AI bots: whether you serve real content server-side, or ship an empty shell that depends on client-side rendering.
• AI-crawler directives: what your robots.txt and llms.txt tell GPTBot, ClaudeBot, PerplexityBot, and Google-Extended they are allowed to do.
• Content structure: whether your page is built in clean, answerable chunks with real headings, or one undifferentiated wall.

Why the line sits at 75

75 is our threshold, not an industry standard. We set it on our own rubric after watching where sites cross from invisible to citable. The rough math is simple. Score the four categories, weight them by how often each one is the actual reason a model skips a page, and you get a number. Below 75, at least one load-bearing category is failing hard enough that the others cannot carry the page. A site can have flawless schema and still fail, because if ClaudeBot fetches an empty shell, the schema it never saw counts for nothing. The line is where every category is at least competent and no single failure sinks you. Above it, the AI surfaces start pulling your content into answers. Below it, you are background.

A clean SEO score and a failing AEO score live in the same site more often than not. The two systems are reading for different things.

Fix crawlability first

When a site comes back under 75, crawlability is usually the cheapest, biggest win. If a non-rendering bot hits your page and gets a shell with no content, nothing else you do matters, because the model has nothing to read. Server-side render the content you want quoted. Confirm your robots.txt is not quietly blocking GPTBot or PerplexityBot. Add an llms.txt that points the crawlers at what counts. Then move to structure and schema. We do this work as an Improve engagement, and we guarantee a +20 on the rubric. In practice we have delivered at least +25. The first chunk of that almost always comes from making the page legible to the bots in the first place, before anyone touches a single word of copy.

Run the free Beacon scan, get your number, and look at which of the four categories is dragging it down. If you are under 75, do not start by rewriting headlines. Start by checking what GPTBot actually sees when it fetches your page. That is where the points are.
