Why a lower score means more work worth doing
The composite score is a pain measurement, not a quality badge. Inverting the usual convention is the whole point of the product.
The most common question we get about the product is a bug report: "the scores look inverted". They are. A site scoring 92 is in great shape. A site scoring 31 is falling apart. And it is the 31 that has a month of work in it.
Every other tool scores the site; this one scores the opportunity
Lighthouse tells a site owner how their site is doing. That is the right frame when the reader owns the site. It is the wrong frame when the reader is deciding which of two hundred businesses to call, because the thing being ranked is not website quality. It is how much fixable, provable, sellable pain exists.
Once you name the number for what it is, the inversion stops being confusing. It is a pain score. High pain, low number, more to fix.
Pain is not the same as badness
A dead domain scores terribly and is worth nothing: there is no business behind it to sell to. A brand-new one-page site scores poorly and may belong to someone with no budget. The score is one input, which is why it sits next to review count, rating, category and segment in the queue rather than replacing them.
The signal we have found most reliable is not the lowest composite. It is a low composite attached to a business that is visibly succeeding elsewhere. Four hundred reviews, a 4.7 average, and a site that takes six seconds to load is a business losing money it can measure, run by someone who already knows how to invest in the business. That is the call worth making.
Weighting decides whose pain you see
The same city ranked by a security consultancy and by an SEO shop should not produce the same order. Scoring profiles re-weight the categories around what you actually fix, so "worst first" means worst for you. A studio that builds sites weights performance and conversion; a compliance practice weights accessibility and cookies; the underlying measurements do not change at all.
Why the report does not show the score
Deliberately: the report opens with their grade and their findings, not with the pain score that sorted them. The number is an internal ranking device. Handing a business owner a document that leads with how much work their site represents to you is a strange way to start a relationship, and the findings explain the work perfectly well on their own.
The scoring documentation lists the categories and the profiles that weight them, the methodology gives the standard behind each check, and the features page shows how the ranking feeds the report.
