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 4.6/10, PHP CAPTCHA Guide is crawlable but under-signaled - fixable, and the signals above are where to start.

Image CAPTCHAs are easy for modern bots to solve, hurt accessibility, and kill form completion rates.
