What it reads
Four things that take a site offline or out of search without failing an uptime check. Each has its own checker if you want just one.
Certificate
When it expires, who issued it, and whether it actually covers the name you typed.
SSL certificate checkerRegistration
When the domain expires at the registry, the registrar, and whether the transfer lock is on.
Domain expiry checkerWhether SPF, DKIM and DMARC are published, and whether receiving servers will trust what it sends.
DMARC checkerIndexing
Whether a noindex rule or a robots.txt is quietly telling search engines to stay away.
HTTP status code checkerTen sites free, for real work
No card, no trial timer, and every check on every plan. Create an account, add your first site, and see what it finds.
