The BOOSTD Growth Score: how it’s calculated and what it doesn’t claim

The Growth Score is a single number from 0 to 100 that shows where a business stands at a glance without hiding the evidence. Every overall score opens into category scores, and every category into the checks behind it.

It’s built from up to eleven categories, weighted by the type of business. A category only counts if it applies to that business and there’s enough evidence to score it.

Each category score that applies is multiplied by its weight, the results are added up, and the total is divided by the sum of the weights used. A weight of zero, such as local presence for an online-only shop, means the category plays no part.

A category that doesn’t apply, or has fewer than two checks behind it, is left out of both sides of that sum rather than counted as zero. That’s the difference between "we couldn’t measure this" and "this is bad".

Every saved score records the method version, the weights used, when each source was read, which categories didn’t apply, and the raw measurements. That keeps before-and-after comparisons fair when the method changes.

Alongside the current score, BOOSTD can show a potential score: what the current score would become if the fixes it found were done. Each improvement is discounted by how likely it is to work, and none is ever treated as more than 85% likely.

A potential score shows an opportunity we’ve modelled. It isn’t a forecast of rankings, traffic or revenue, and we never present it as one.
