How do I check for heading hierarchy errors?

Use the `check_hierarchy` tool by providing an array of objects containing the level and text of your headings. Tools available: `your_tool_name`.

Can I verify specific keywords in my H2 tags?

Yes, use `verify_keywords` and specify the target level as 'h2' to check for your required terms.

What is semantic density?

It is a measure of how much unique, meaningful information is present in each heading level compared to the total word count, calculated via `calculate_semantic_density`.
