backmarket.com — Global SEODiff Score 63/100

backmarket.com
📊

backmarket.com shows strong AI visibility with an ACRI of 80/100, outperforming 94% of indexed domains. In the infrastructure sector, backmarket.com outperforms the average (57), 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 50.0× token bloat ratio means crawlers must process significantly more tokens to reach the actual content — a drag on extraction efficiency. The site includes 3 schema blocks, providing adequate structured data for basic entity recognition. Robots.txt grants unrestricted access to the key AI user-agents, which is the strongest starting position for AI visibility.
