A duplicate H1 usually means your theme or page builder is rendering one heading and your content has a second one pasted in. The Bulk Editor's Health column gives you a quick signal per page; Edit Headings shows you exactly what's underneath so you can fix it across every affected page in one batch.
Scan your site in the Bulk Editor, and each row gets a quick health indicator before you open anything.
Open Edit Headings on a flagged row to see the actual structure.
Every page gets a Health indicator in the grid, giving you a quick read before you open anything.
The panel shows every heading on that page, including tag level, so you can see which one is the theme's title output and which was added inside the content.
Retag the heading that shouldn't be an H1, typically the one inside the content, down to an H2, keeping its text unless that also needs a rewrite.
Select every page carrying the same pattern and apply the same fix in a single save.
Preview Changes shows the current tag and new tag for every row before saving, with an automatic backup taken so the change is reversible from History.
Most duplicate-H1 cases come from a theme change or page-builder default that adds its own title heading on top of content that already had one. Bulk SEO Studio's Edit Headings panel reads from the actual block or tag structure, not from styling, so it shows you the real heading count rather than a guess.
Usually a theme or page-builder template outputs its own H1, and a second H1 exists inside the content itself.
Not inherently penalized by Google, but unclear heading structure makes it harder for search engines and AI answer engines to identify the page's primary topic.
Open Edit Headings on that row to see the actual heading structure, rather than relying on the Health dot alone.
The scan is free. See the full report before you commit to a single edit.
