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
- 0.4 applied to every site type unless overridden below
- Why this weight
- BIMI is a brand-display feature in mail clients. Aspirational — only worth it once DMARC is enforced.
Per-site-type overrides
| Site type | Weight | Δ vs base |
|---|---|---|
| E-commerce | 0.7 | +0.3 |
| News / Publisher | 0.6 | +0.2 |
| Personal site | 0.1 | -0.3 |
| Media / Streaming | 0.6 | +0.2 |
Site types not listed inherit the base weight.
What this means for your business
When this is set up, Gmail and Apple Mail can display your verified logo in the inbox next to messages from your business — which both looks more professional and helps customers spot real email from you versus impersonators.
Plain title: Shows your logo next to your emails
What we measure
BIMI displays your verified logo next to your emails in Gmail/Apple Mail. Requires DMARC enforcement + a Verified Mark Certificate (VMC). Strong trust signal.
How to improve your score
Get DMARC to `p=quarantine`+, obtain a VMC from DigiCert/Entrust (~$1k/yr), publish BIMI TXT record pointing at your SVG logo.
