How the website grader works, and why the score wobbles

Class Company US · Updated August 29, 2026
The Tarvis Site Scan reads a website like a stranger with a wallet, files every finding into six leak families, and scores the whole picture out of 100. Because it is an AI audit, the score wobbles a few points between runs; the flags are the signal. 95 is the ceiling a scan can verify alone.

What the scan actually checks

The Tarvis Site Scan reads your site the way a stranger with a wallet does, then reports where money leaks out between a visit and a sale. Every finding lands in one of six leak families:

Each finding carries a severity (critical, major, minor). The score out of 100 and the letter grade summarize the whole picture, and the biggest leak is named plainly at the top of the report.

Why two runs can give different numbers

The grader is an AI audit, not a caliper. Run it twice on an unchanged site and the score can move a few points, because the auditor re-reads the site fresh each time, the way two human consultants would not file identical reports. We know this because we point the scanner at our own site constantly: in one evening of testing it graded us 72, then 69, then 77.

So here is how to read your report: the digits are an estimate, the flags are the signal. The same real leaks surface run after run, and those repeat offenders are what actually cost money. That is also why our fix guarantee re-grades on the same scanner version as your original scan, alongside Google PageSpeed numbers you can verify yourself, so nobody is judge and jury with a moving ruler.

Why 95 is the self-serve ceiling

A scan can verify a lot from the outside: your first screen, your capture paths, your speed, your trust signals. It cannot verify that real bookings complete, that real replies arrive within minutes, or that real customers vouch for you. Those last points need hands-on checks, which is why no self-served site scores above 95 and why a 100 always has human verification behind it. The ceiling is a limit of scanning, not a paywall.

How we keep ourselves honest

We run this exact scanner on classcompanyus.com every night at 3am Central, automatically, and publish the result whether it flatters us or not. The whole record, including the night our own scanner caught us cutting corners and graded us DOWN, lives at classcompanyus.com/blog/we-graded-ourselves. If our published score and a scan you run yourself ever disagree by more than the normal wobble, we have to answer for it in public.

Questions people also ask

Why did my score change when I re-ran the scan?

The grader is an AI audit, and like any estimate it wobbles a few points between runs even on an unchanged site. Our own site moved between 69 and 77 in a single evening of testing. Trust the flags more than the digits: the same real leaks show up run after run, and those are what cost money.

Is the grader tilted to sell the 490 fix?

No, and you can check that claim: we run the same scanner on our own site every night and publish the score, including the embarrassing ones. A grader that flattered anyone, us included, would be useless. The 95 ceiling exists because a scan cannot verify hands-on things, not because paying unlocks points.

Can I use the scan without buying anything?

Yes. The scan is free, the full report is free by email, and most flagged leaks come with a fix a site owner can do themselves in an evening. The 490 flat service exists for owners who want the top three leaks fixed for them within 72 hours.
