mgen.fr — Global SEODiff Score 81/100

mgen.fr
📊

mgen.fr achieves a 81/100 on the AI-Crawler Reality Index, reflecting above-average readiness for AI-driven discovery. In the infrastructure sector, mgen.fr outperforms the average (57), suggesting strong competitive positioning in AI search. The low ghost ratio (0%) confirms that what crawlers see matches what users see — a hallmark of strong SSR implementation. The token bloat ratio sits at a lean 3.1×, meaning the ratio of code to visible content is efficient — crawlers spend their token budget on actual information. The site includes 3 schema blocks, providing adequate structured data for basic entity recognition. All major AI bot user-agents (GPTBot, ClaudeBot, CCBot, Google-Extended) are permitted by robots.txt, ensuring broad AI crawler access.
