Top issues to fix
6 issues found · 2 high priority
Missing Strict-Transport-Security header

Missing Content-Security-Policy header
SecurityAdd a CSP to control which sources can run scripts — the strongest single defense against XSS.
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.
sitemap.xml not found
SEOPublish an XML sitemap and reference it from robots.txt to speed up page discovery.
1 broken link on the page
SEOFix or remove broken links — they waste crawl budget and erode user trust.
