Priority fixes for linear.app
Ordered by impact and by how common each practice is among peers.
Priority 1 · Enable
Structured data present
Observed: The homepage had no JSON-LD structured data.
Why it matters: Structured data helps search engines understand your organization, products or articles, and is needed for some rich results.
What to do: Add JSON-LD for your organization and main content types, then test it with Google's Rich Results Test.
50% of Workplace Productivity peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.
Priority 2 · Harden
CAA records limit who can issue certificates
Observed: No CAA record was found for linear.app, 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.
18% of Workplace Productivity peers do this.
Priority 3 · Harden
DNSSEC signed
Observed: No DS record was found for linear.app 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.
12% of Workplace Productivity peers do this.

Priority 4 · Recover
Nameservers spread across providers
Observed: All nameservers for linear.app belong to Cloudflare.
What to do: Treat this as an advanced step. Add a secondary DNS provider through zone transfers or a multi-provider setup, then test changes carefully, since both providers must stay in sync.
On Cloudflare: Cloudflare supports zone transfers for primary or secondary DNS setups on eligible plans.
4.8% of Workplace Productivity peers do this.
