H1 tag presence

live factor #13 · SEO & Discoverability · scoring impl: implemented · weight 0.7%

What we measure

An H1 is your page's main headline. Google uses it to understand what the page is about. Missing it forces Google to guess from less reliable signals.

How to improve your score

Add a single `<h1>` tag containing the page's primary topic. Many WordPress themes use `<p class="page-title">` instead — switch to a real heading tag.

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.
