Top issues to fix

4 issues found · 1 high priority

  • Missing Strict-Transport-Security header

    Security

    Add HSTS so browsers always use HTTPS — this closes the protocol-downgrade attack window.

  • Multiple H1 headings found

    SEO

    Keep a single H1 per page and demote the others to H2/H3.

  • No structured data (JSON-LD) found

    SEO

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

  • 3 broken links on the page

    SEO

    Fix or remove broken links — they waste crawl budget and erode user trust.
