How do you check heading tags for a webpage?

To check heading tags (like H1, H2, H3), you can view the page's HTML source code and search for '<h1', '<h2', etc. A much easier way is to paste the full HTML source code into our tool. It will automatically find and display all heading tags in a clean, structured list, showing you if you have missing or duplicate H1s.

What is a keyword density checker?

A keyword density checker analyzes a block of text to show you how often a word or phrase (like 'check heading tags') appears, relative to the total word count. This helps SEOs and writers ensure their content is properly optimized for a target keyword without 'keyword stuffing'.

Is this HTML analyzer tool secure?

Yes. This tool is 100% client-side. All analysis, including parsing your HTML, checking heading tags, and calculating keyword density, happens in your web browser. No data is ever sent to our server, so your content or a competitor's HTML source code remains completely private.
