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
- Newsletter signup detection — marketing tactic, not web quality. Penalizing news/SaaS sites for not running an email list is off-mission. The fact remains in the breakdown for descriptive purposes; not weighted in the composite.
What this means for your business
An email signup form lets a curious visitor become a future customer instead of a one-time tab close. For most local businesses this is the single cheapest way to bring people back without paying for ads every time.
Plain title: A way for visitors to stay in touch
What we measure
A newsletter signup is the highest-ROI lead capture mechanism on most business sites. Visitors who'd happily hear from you again leave without it, and never come back.
How to improve your score
Add a signup form to your footer at minimum, ideally also above the fold or as a non-intrusive popup. Connect to Mailchimp, ConvertKit, Beehiiv, or any free-tier ESP.
Facts
Implementation notes
Detect `<form>` elements with email input + subscribe-related text/action. Pattern-match action URLs against known ESP domains.
When this applies
Newsletter signup forms are not graded on personal sites.
- Marked n/a for site types: Personal site.
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.
