Borderline visible. AI bots can crawl PDF Locker, but the structured-data signals are thin - you are at real risk of being skipped when buyers ask ChatGPT, Claude, or Perplexity for a recommendation.

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 4.7/10, PDF Locker is crawlable but under-signaled - fixable, and the signals above are where to start.
