LSI Words in H5 Tags counts how many times the page’s related terms (its LSI list) appear inside H5 headings, returning a whole-number occurrence count. It is a descriptive observation about a rarely used heading level, not a target to chase — most pages need few or no H5 elements at all.

What it measures
This factor counts LSI term occurrences within H5 headings. RankGear takes the run’s LSI list — the related terms it has associated with the query — and tallies every time one of those terms surfaces in the text of an H5 element. The result is a single count for the page, reflecting how far the fifth heading level restates the page’s related vocabulary.
How RankGear measures it
RankGear parses each H5 on the page and totals case-insensitive, word-aware matches for every item in the run’s LSI list. Matching ignores letter case and respects word boundaries, so a term is counted where it appears as a whole word rather than as a fragment inside a longer word. Every H5’s contribution is summed into one page-level count.
How to read it
| If the count is… | What it indicates |
|---|---|
| 0 | No related terms appear in H5 text — often simply because the page has no H5 elements, or the LSI list is empty. Normal for most pages. |
| 1 or more | Related vocabulary is present at the H5 level. Higher counts reflect more related-term text (and repeats of the same term add to the total), not higher heading quality. |
How to optimize it
Treat this as an observation, not a target. Include a related term in an H5 only when the page naturally requires that hierarchy level and the phrase genuinely clarifies the subsection. Do not add H5 headings, or stuff related terms into them, to move the number — the factor rewards nothing beyond terms that a real content structure already calls for. On most pages the honest value here is 0, and that is fine.
Important considerations
- Empty LSI lists and pages with no H5 elements both return 0.
- Repeated terms increase the count — the same term used twice counts twice.
- The factor does not assess heading quality, only related-term occurrences.
- Most pages require few or no H5 elements, so a low or zero count is expected and unremarkable.
- This is a correlation-based prioritization signal measured within a result set. It relates to position; it does not make a page rank or guarantee any ranking.
