Top issues to fix

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.
sitemap.xml not found
SEOPublish an XML sitemap and reference it from robots.txt to speed up page discovery.
20 broken links on the page
