Top issues to fix
6 issues found · 2 high priority

SecurityAdd HSTS so browsers always use HTTPS — this closes the protocol-downgrade attack window.
No H1 heading found
SEOAdd exactly one H1 describing the page's main topic — it anchors the document outline for search engines and screen readers.
Missing X-Content-Type-Options header
SecurityAdd X-Content-Type-Options: nosniff to stop MIME-sniffing attacks.
Missing X-Frame-Options header
SecurityAdd X-Frame-Options (or a CSP frame-ancestors rule) to prevent clickjacking via hidden iframes.
Meta description longer than 160 characters
SEOTrim the meta description to under 160 characters to avoid truncation in search results.
8 broken links on the page
SEOFix or remove broken links — they waste crawl budget and erode user trust.
