Internal tool — no external data collection.
Whether you're auditing heading hierarchy, testing keyword placement, or documenting changes — Heading Injector handles it without ever opening a staging environment.
Instantly surface the full heading structure of any live page. Identify hierarchy gaps, duplicate H1s, and skipped heading levels at a glance.
Click any heading in the table to edit its text live on the page. Test keyword variations and see how changes affect the visual layout before flagging for implementation.
Every edit is tracked automatically in the Activity Log. Document your recommendations, export change records, and streamline developer handoffs.
No developer setup, no API keys, no staging environment. Just open a URL and click the icon.
Open any live URL — a product page, blog post, category page, or competitor site — that you want to analyze for heading structure and SEO optimization.
Click the Heading Injector & Previewer icon in your Chrome toolbar. The extension immediately scans the DOM and populates the heading table with every H1–H6 on the page.
Review the heading hierarchy, click any row to edit text inline, and watch your changes render live on the page. Use the Activity Log to capture every modification for your team.
The extension UI is purpose-built for speed — no learning curve required.
