  • No structured data (JSON-LD) found

    SEO

    Add JSON-LD (Organization, Article, Product…) to become eligible for rich results.

  • Missing OpenGraph tags

    Add og:title/og:description/og:image so shared links render a proper preview card.

  • More than 20% of images are missing alt text
