AEO Score — Be the Answer in AI Search
When someone asks ChatGPT, Perplexity, Claude or Gemini a question, the assistant writes one answer and quotes a handful of sources. Answer Engine Optimization (AEO) is the work of becoming one of those sources. The NOXEL AEO Score reads a page the way an answer engine would and tells you, category by category, how ready it is to be quoted.
Eight categories, one score out of 100
Enter a URL and NOXEL fetches the page, then grades it on eight groups of signals:
- Structured Data: JSON-LD, FAQ and HowTo schemas that state facts in a machine-readable form.
- FAQ Content: question-and-answer passages an assistant can lift as a direct reply.
- Content Structure: headings and sections that make each answer easy to locate.
- Entity Clarity: brand identity signals that tell a model who is speaking.
- Content Depth: word count, data and examples, the material a cited answer needs.
- Content Freshness: date signals and last-modified information.
- Trust & E-E-A-T: author details, credentials and a privacy policy.
- AI Crawlability: whether your robots.txt blocks AI crawlers such as GPTBot or PerplexityBot, and whether you publish an llms.txt file.
Each category shows its own score and a short list of tips, so the weakest area is obvious at a glance.
Generate a starting llms.txt
llms.txt is an emerging convention that tells AI engines which content on your site they may use, a little like robots.txt for language models. After a scan, the AEO page shows a starting llms.txt for your domain, which you can adapt and publish at the root of your site.
How AEO differs from classic SEO
Ranking in Google rewards the page as a whole. Being cited by an assistant rewards a passage: one clear, self-contained answer, backed by structure and a source the model can trust. A page can rank on the first page and still never be quoted. The AEO Score isolates that second question, and the GEO Score complements it by looking at how models understand and reformulate your content.
