Missing H1
The <h1> is the page's main heading - the clearest on-page signal of what the page is about.
What it is
This check flags content pages with no <h1> element.
Why it matters for SEO
A missing H1 weakens topical clarity for search engines and harms accessibility and document structure.
Example
<body>
<p>Welcome...</p> <!-- no h1 -->
</body>
How to fix
- Add a single, descriptive
<h1>stating the page topic. - Align it with the title and primary keyword.
- Use
<h2>/<h3>for subsections beneath it. - Re-crawl to confirm each page has one H1.
