Priority fixes for thebestpdf.com
Ordered by impact and by how common each practice is among peers.
Priority 1 · Enable
XML sitemap discoverable
Observed: No sitemap was listed in robots.txt or found at /sitemap.xml.
Why it matters: A sitemap helps search engines find new and updated pages, especially on large or frequently updated sites.
What to do: Generate an XML sitemap of canonical URLs, reference it in robots.txt and submit it in Google Search Console.
73% of Web Tools peers do this. Limit: Only the standard location was requested, once, at the time of the check.
Guide: XML Sitemap Guide: Include Only URLs You Stand Behind
Priority 2 · Harden
HSTS kept for at least a year
Observed: The homepage response did not include a Strict-Transport-Security header.
What to do: Send Strict-Transport-Security on HTTPS responses. Start with a short max-age (for example 300 seconds), confirm every subdomain works over HTTPS, then raise it in steps to 31536000. Add includeSubDomains only when all subdomains are HTTPS. HSTS preload is optional and hard to undo; hstspreload.org itself does not recommend it by default.
On Amazon CloudFront: Attach a response headers policy with Strict-Transport-Security to each distribution.
30% of Web Tools peers do this.
Priority 3 · Enable
Canonical URL declared
Observed: The homepage did not declare a canonical URL.
What to do: Add a self-referencing canonical link to every indexable page, using the final https:// URL.
74% of Web Tools peers do this.
Priority 4 · Harden
Certificate lifetime of 100 days or less
Observed: The certificate from Amazon had a 197-day validity period, longer than the 100-day maximum that applies from March 2027.
What to do: Move to automated issuance and renewal now, while you still have time to test it.
87% of Web Tools peers do this.
