Top issues to fix

5 issues found · 2 high priority

  • Missing Strict-Transport-Security header

    Security

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

  • Missing Content-Security-Policy header

    Security

    Add a CSP to control which sources can run scripts — the strongest single defense against XSS.

  • robots.txt not found

    SEO

    Publish /robots.txt with a Sitemap: directive to guide crawlers.

  • sitemap.xml not found

    SEO

    Publish an XML sitemap and reference it from robots.txt to speed up page discovery.

  • 20 broken links on the page

    SEO

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