Heading structure is one of the most frequent on-page SEO checks. Every page you audit. Every page you build.
H-Tag Checker: one shortcut. Every H1 through H6 lights up in color. The page itself becomes the heading report.

The Old Way: Hunt for Headings
One element at a time.
Right-click. Inspect. Expand the DOM tree. Hunt for heading tags one element at a time.
Or View Source. Ctrl+F for “h1”. Count manually. Hope you didn’t miss any.
Or install a browser extension that shows headings in a separate panel while you try to match them to page locations.
You’re not auditing the structure. You’re playing “find the heading tag.”
The on-page SEO tools run heading checks in a single keystroke.
