What does Domain health check?

Domain health checks how your domain is set up for e-mail and DNS, from the same public records anyone on the internet can read. Nothing is installed and no mail server is contacted.

Where to find it

Open the project's SEO audit (or the Health overview). Under the audited domain there is one row, Email and hosting, with the number of issues and the host. Press Details for the drawer with four tabs: Summary, Email, DNS and Hosting.

What it checks

• Email: your mail servers (MX), SPF, DKIM and DMARC under the current and older standards, and mail transport security: whether mail to you must travel encrypted (MTA-STS, DANE) and whether you get TLS reports. When MTA-STS is missing or wrong, the fix steps include the policy file to publish.
• DNS: the answers your domain gives, registration data from the registry (registrar, status, dates; no owner contact details are kept) with warnings for expiry, holds and a missing transfer lock, and DNS changes: a snapshot whenever your records change, with the changes grouped. You can also note a planned migration ahead of time.
• Hosting: who provides each part of the domain (registrar, DNS, e-mail, CDN, network, hosting), each labelled confirmed, strongly indicated or uncertain.

Honest about what is unknown

DKIM keys live under a name (a selector) only your mail provider knows. When SEOmise finds none, it says it did not find one rather than "DKIM missing"; add the selector you use and check again. Anything that could not be read is said in words, never shown as a problem or as 0.

Fixing a finding

Each finding shows what was read, where and when, and copy-ready records with steps for the place your DNS is managed. Make the change there, then press Recheck. A finding can become a task on your to-do list; the task closes only when a new check shows it fixed.

Historical DNS, an uptime import and provider status pages are prepared but stay locked until SEOmise has a licensed source for them.
