Priority fixes for habr.com
Ordered by impact and by how common each practice is among peers.
Priority 1 · Enable
Meta description written
Observed: The homepage had no meta description.
Why it matters: Search engines often use it for the snippet under your link, so a clear description can improve click-through.
What to do: Write a short, specific description of the page for people, not a list of keywords.
94% of Online Publishing peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.
Guide: Meta Titles and Descriptions That Match Search Intent
Priority 2 · Accelerate
HTTP/3 advertised
Observed: The homepage did not advertise HTTP/3 through an Alt-Svc header.
What to do: Turn on HTTP/3 at your CDN. Browsers fall back to HTTP/2 automatically, so the risk is low.
41% of Online Publishing peers do this.
Priority 3 · Harden
Certificate lifetime of 100 days or less
Observed: The certificate from Sectigo Limited had a 387-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.
71% of Online Publishing peers do this.
Priority 4 · 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.
64% of Online Publishing peers do this.
