How fast it renders
The time to first byte, the largest element on the page, the layout shift a visitor feels and the total blocking time. Then the part that matters, which is what is causing them.
One run that answers the three questions a slow site always raises. Is it slow, can search engines read it, and is it set up safely. Performance, the SEO crawl and the security headers in one report, with no account.
What comes back
The time to first byte, the largest element on the page, the layout shift a visitor feels and the total blocking time. Then the part that matters, which is what is causing them.
The title, the description, the canonical, the robots directives and the structured data, followed by the crawl that shows which pages link to which and which are stranded.
Transport security, framing, content type sniffing, referrer policy and permissions. These cost nothing to set and are absent on most sites, which is why a scanner finds them.
Links and images that do not resolve, and the difference between a page that is gone and one that merely refused this crawler. Only the first is something you have to fix.
Running it once, and running it always
This tool tells you what your site looks like right now. That is a real answer and it is the one you need before you change anything. It cannot tell you what changed last Tuesday, or that a certificate expires in nine days.
EnterraMon Pro
Uptime, response time, DNS, SSL expiry and mail records, watched continuously and kept as history. The audit tells you the certificate is fine today. EnterraMon tells you when it stops being fine, which is the difference between a report and a warning.

The audit crawls what it can in one run. EnterraSEO crawls the site properly, tracks rankings and technical faults as they change, and reports the movement rather than a single snapshot. If the audit finds something, this is where you watch it get fixed.

The individual checks are live and free, and the two products behind this audit are already watching sites.
