ublockorigin.com — Global SEODiff Score 78/100

ublockorigin.com
📊

With a solid 78/100 ACRI, ublockorigin.com is well-positioned for AI search — better than 88% of sites in the Radar. In the developer sector, ublockorigin.com outperforms the average (57), suggesting strong competitive positioning in AI search. Its server-rendered architecture ensures AI crawlers receive complete HTML on first request, a key advantage for extractability. The token bloat ratio sits at a lean 2.5×, meaning the ratio of code to visible content is efficient — crawlers spend their token budget on actual information. Rich structured data (4 schema blocks) gives AI systems strong semantic signals for entity recognition and knowledge graph inclusion. All major AI bot user-agents (GPTBot, ClaudeBot, CCBot, Google-Extended) are permitted by robots.txt, ensuring broad AI crawler access.
