H1 Count (RG-SIZ-008) reports how many <h1> elements RankGear finds in a page’s parsed document. It is a plain quantity — not a judgment of heading quality, relevance, or accessibility — so read it as an observation to weigh against competitive evidence, never a number to force up or down on its own.

What it measures
This factor reports the number of parsed <h1> elements on the page. The H1 is conventionally the page’s top-level heading — the single most prominent title of its content — though HTML permits more than one. The value is a straight count of how many <h1> tags exist in the document RankGear parsed, nothing more.
How RankGear measures it
RankGear parses the rendered HTML document, selects all <h1> elements, and returns the count. It counts the elements as they appear in the parsed document at capture time; it does not weigh their text, position, styling, or whether each one is semantically appropriate.
What RankGear looks for
<!-- each of these adds 1 to the count -->
<h1>Primary page heading</h1>
<h1 class="visually-hidden">Section title</h1>
<!-- not counted: other heading levels -->
<h2>A subheading</h2>| If the count is… | How to read it |
|---|---|
| 0 | No <h1> was parsed. Check whether the primary heading is missing, marked up at another level, or only rendered after capture. |
| 1 | A single top-level heading — the conventional pattern for one clearly-titled page. |
| 2 or more | Valid in HTML, but confirm each <h1> serves a distinct structural purpose rather than being an accidental duplicate. |
How to optimize it
Use an H1 for the page’s primary visible heading and make the heading hierarchy understandable. Multiple H1s can be valid in HTML, but each should serve a clear structural purpose. Treat this factor as an observation rather than a target: compare competitive evidence, but do not assume more is always better, and do not add or remove headings purely to move the number.
Important considerations
- This is a quantity measure, not an assessment of quality, relevance, accessibility, or usefulness.
- JavaScript-rendered markup present at capture time can affect the parsed document, and therefore the count.
- Malformed HTML may be normalized by the parser, which can change how many <h1> elements are recognized.
- Compare competitive evidence, but do not assume more is always better.
- This factor relates to position within a measured result set; it is a prioritization signal, not a guarantee that any H1 count makes a page rank.
