Free SEO H Tag Checker Chrome Extension — Instantly Audit Headings & Paragraphs

As an SEO specialist and web developer, one of the most important (and often overlooked) aspects of website optimization is the structure of your content. Properly organized headings (H1–H6) help both users and search engines understand your content hierarchy — and impact your SEO performance. I highly recommend the Detailed SEO Plugin, which does show the number of H Tags on a particular page. I use it all of the time to make sure my pages are structured correctly.

The missing piece for me is to see which section is the H1 tag and which are the H2 tags and so on. That’s why I created SEO H Tag Checker — a simple, free Chrome extension that makes inspecting heading tags effortless.

SEO H Tag Checker is a lightweight (only 109kb) yet powerful Chrome extension that simplifies the process of auditing heading and paragraph tags across any website. With a single click, you can instantly highlight and visually inspect all H1–H6 and paragraph tags, helping you understand content hierarchy at a glance. Color-coded outlines and floating labels make it effortless to spot SEO issues like missing headings or improper structure, so you can optimize your pages faster and more accurately.
