Understanding a website score

What a heuristic score measures, and what it cannot tell you.

Updated 10/14/2026

A website score is a summary of the checks we could actually run on the pages we collected. It is not a ranking prediction, a traffic forecast or a judgement of the business behind the site.

What goes into the score Each check looks for something observable: a page title, a description, headings in a sensible order, readable text, clear contact details, structured data, and so on. Every passing or failing check is backed by evidence taken from the page itself.

Unknown is not the same as failing Some checks need extra evidence, such as a live speed test or a reading of what the page means. When we can't gather that evidence, the check is marked "needs more evidence". It is left out of the score rather than counted against you.

When we don't publish a score If too few checks could be answered, we show "score not published" instead of a number. A score built on thin evidence would be misleading.

How to use it Read the individual findings, not just the number. Fix the highest-impact items first, then run the report again to see what changed.
