Among all indexed domains, 4yuuu.com ranks in the top echelon with an ACRI of 87, demonstrating that its content is highly visible to AI systems. Its server-rendered architecture ensures AI crawlers receive complete HTML on first request, a key advantage for extractability. With a 3.1× bloat ratio, the page delivers its content without excessive boilerplate, giving AI systems a clean extraction path. Structured data coverage is solid at 3 blocks, covering core entities — expanding to include FAQ or Breadcrumb schemas could strengthen the profile further. All major AI bot user-agents (GPTBot, ClaudeBot, CCBot, Google-Extended) are permitted by robots.txt, ensuring broad AI crawler access.
