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
0.3 applied to every site type unless overridden below
Why this weight
Domain age is a weak signal at best — penalises legitimate rebrands. Held low intentionally.

Per-site-type overrides

Site type Weight Δ vs base
E-commerce 0.5 +0.2
News / Publisher 0.4 +0.1

Site types not listed inherit the base weight.

Same factor, two depths.

What we measure

Older domains earn more trust from Google and visitors. A 15-year-old domain is treated very differently than a 6-month-old one.

How to improve your score

This is just a function of time. Don't let the registration lapse.

Scoring

Scoring formulas are versioned with the methodology. The current method (v1.2.0) maps raw measurements to pass, warn, fail. Factor weights determine how much each contributes to the composite — see the methodology index for the full table.
