What this score means
Your AEO score measures whether AI search engines - ChatGPT, Claude, Perplexity, Gemini - can actually read your site and cite it in answers. Roughly two-thirds of sites are invisible to them. At 4.9/10, functionalphp.com is crawlable but under-signaled - fixable, and the signals above are where to start.
