Missing Content-Security-Policy header

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.
Multiple H1 headings found
SEOKeep a single H1 per page and demote the others to H2/H3.
