Every page is held to one rulebook, in the order a crawler meets a site. The rules and their weights are our own. What they add up to is below, and every finding on a report names the rule behind it.
How does mttr score a site?
Every page is checked against one rulebook in four stages: access, understand, trust and act. A stage scores the share of its checks that pass, each counted by its rule’s weight, and the four add up by their share of 100 points. A site that keeps crawlers out is held at 20 or less.

Access
Can it be fetched and indexed at all?
A crawler meets this first, and nothing after it counts if the door is shut.
It gates the rest: a site closed to crawlers is held down, whatever else it does well.

Understand
Can a machine tell what each page says, and lift an answer from it?
Search engines and assistants quote what they can take whole: a clear subject, and answers set out plainly.
Every rule passes or fails by code. Where a model gives an opinion and is unsure, the page goes to a person.
Not cheap to game
A check that can be met without helping a reader measures nothing, so it is not a rule.
Never more than it read
A read that stopped at its limit says so, and claims nothing it could not see.
Closed means closed
While a site keeps crawlers out, nothing else on it can be found, and the score says so.
Only what anyone can see
Public pages, by their public address. Never a page behind a sign-in, a form, or an address inside a network.
As polite as a person
It follows robots.txt, reads a few pages at a time, and says who it is in every request.
It needs no access to your site
mttr reads public pages only. Your agent makes each change with the access it already has, fully automated or with your approval by email, and mttr grades every one on the live site.
