sfxengine.com — Global SEODiff Score 63/100

sfxengine.com
📊

sfxengine.com shows strong AI visibility with an ACRI of 79/100, outperforming 91% of indexed domains. Compared to other saas sites (avg score: 58), sfxengine.com performs above the benchmark, suggesting strong competitive positioning in AI search. Server-side rendering keeps the ghost ratio near zero, giving AI systems direct access to all visible content. A 48.9× token bloat ratio means crawlers must process significantly more tokens to reach the actual content — a drag on extraction efficiency. Structured data coverage is solid at 2 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.
