Priority fixes for freecodecamp.org
Ordered by impact and by how common each practice is among peers.
Priority 1 · Enable
Canonical URL declared
Observed: The homepage did not declare a canonical URL.
Why it matters: A canonical link tells search engines which URL to show when the same page is reachable at several addresses.
What to do: Add a self-referencing canonical link to every indexable page, using the final https:// URL.
66% of Education & Online Learning peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.
Priority 2 · Enable
Structured data present
Observed: The homepage had no JSON-LD structured data.
What to do: Add JSON-LD for your organization and main content types, then test it with Google's Rich Results Test.
43% of Education & Online Learning peers do this.
Priority 3 · Harden
CAA records limit who can issue certificates
Observed: No CAA record was found for freecodecamp.org, so any public certificate authority may issue for it.
What to do: Publish CAA records naming every CA you actually use, including the CAs your CDN uses for managed certificates. Add an iodef contact if you want reports.
On Cloudflare: Cloudflare documents which CAs its managed certificates need; include them in your CAA records.
11% of Education & Online Learning peers do this.
Priority 4 · Harden
DNSSEC signed
Observed: No DS record was found for freecodecamp.org at its parent zone, so its DNS answers are not DNSSEC-signed.
What to do: Enable DNSSEC at your DNS provider, then add the DS record at your registrar. Plan provider moves carefully: a stale DS record can make the domain fail to resolve.
On Cloudflare: Enable DNSSEC in DNS > Settings and add the DS record at the registrar.
8.2% of Education & Online Learning peers do this.
