LSI Words in H1 Tags counts how many times terms from the run’s related-keyword list appear across a page’s H1 headings. It returns a whole-number occurrence count, and the “LSI” label is a legacy name for that supplied term list — not proof of any specific search-engine indexing method.

What it measures
This factor counts occurrences of terms from the run’s related-keyword list across the page’s H1 headings. It shows whether primary headings use vocabulary that RankGear associates with the analyzed topic. The legacy LSI name represents the related terms supplied for the run, not evidence of a particular indexing technique.
How RankGear measures it
RankGear extracts text from all H1 elements in the rendered, script-free body, lowercases the headings, and counts case-insensitive, word-boundary matches for each related-term entry. It sums every qualifying occurrence. If the related-term list is empty, or none of its entries appears in an H1, the factor returns 0.
| Count | How to read it |
|---|---|
| 0 | No related-term entry appears in any H1 — or the run supplied no related terms. |
| 1–2 | A related term anchors the primary heading, tying it to the topic vocabulary. |
| Higher | Multiple H1 elements or repeated terms raise the count; a larger number is not automatically better. |
How to optimize it
Use a related term in the H1 when it clarifies the page’s main topic and reads naturally. The heading should help visitors understand the page immediately, not try to carry every related concept. Place secondary terminology in supporting headings and body content when it does not belong in the primary heading. Treat the count as an observation against the competitive field rather than a target to maximize: use the field to judge whether an H1-related-term gap is meaningful.
Important considerations
- Multiple H1 elements and repeated terms can increase the count.
- Related-term lists vary by query and run configuration.
- A higher count is not automatically better in a primary heading.
- The factor does not assess contextual accuracy.
- Evaluate it alongside H1 exact matches, variations, entities, and heading structure.
- This is a prioritization signal that relates to position within a measured result set — it does not by itself cause or guarantee a ranking.
