Web Quality factor
This factor is part of Web Quality — the weighted 0..100 score that sits above Web Standards. Its weight depends on what kind of site is being measured. Web Standards items take priority; this factor only enters the score once Web Standards passes.
- Base weight
- 0.0 applied to every site type unless overridden below
- Why this weight
- Payment processors — only meaningful where money moves.
Per-site-type overrides

|---|---|---|
| E-commerce | 0.8 | +0.8 |
| Nonprofit | 0.4 | +0.4 |
| SaaS / Product | 0.7 | +0.7 |
Site types not listed inherit the base weight.
