    Add a ~150-character meta description to control your search-result snippet and lift click-through rate.

    Security

    Add X-Frame-Options (or a CSP frame-ancestors rule) to prevent clickjacking via hidden iframes.

  • Multiple H1 headings found

    SEO

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