Modernizr: the feature detection library for HTML5/CSS3
What this score means

4/10 means Modernizr: the feature detection library for HTML5/CSS3 is borderline visible. AI bots can crawl your site but your structured-data signals are thin. You are at risk of being skipped when buyers ask AI for a recommendation.
