Newsletter signup form detected

live factor #79 · Email & Communications · scoring impl: implemented · weight 0.7%

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.

Data source

Data source for this factor is not yet documented.

Implementation notes

Detect `<form>` elements with email input + subscribe-related text/action. Pattern-match action URLs against known ESP domains.

Scoring

Scoring formulas are versioned with the methodology. The current method (v1.1.0) 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.
