Variations in Strong Tags

Variations in Strong Tags counts how many keyword variations appear inside text a page marks as strongly important with the strong element. It returns a variation occurrence count for the cleaned contents of every bounded strong tag — a signal that tracks with position within a result set, not a lever that makes a page rank.

What it measures

This factor counts keyword variations inside text that a page has marked as strongly important. It looks only at what sits within strong elements — the words an author has deliberately emphasized as significant — and reports how many topical variations land there.

How RankGear measures it

RankGear extracts the bounded contents of each strong element, cleans their HTML, and sums case-insensitive whole-word variation matches across the cleaned text. Matching is whole-word and case-insensitive, so emphasis on a variation is counted the same whether it is written in upper or lower case, and partial substrings inside larger words do not count.

What RankGear looks for

<strong>installing a heat pump</strong>   → cleaned, then matched against the variation set
<b style="font-weight:700">heat pump</b>   → not a strong element, not measured
<span style="font-weight:bold">...</span>  → CSS bolding, not measured
If the page is…How to read it
Emphasizing many topical variations in strongEmphasis is likely diluted; reserve strong for genuinely important statements.
Using strong sparingly on truly important linesHealthy — emphasis keeps its meaning where it matters.
Bolding with CSS instead of strongThose words are not measured; the count reads them as absent.

How to optimize it

Use strong selectively for genuinely important statements, letting topical terms appear inside it only where emphasis actually helps comprehension. Treat the count as an observation about how a page uses emphasis, not a target to inflate — adding strong around keywords purely to raise the number works against the purpose of emphasis.

Important considerations

  • CSS bolding without a strong element is not measured — only real strong tags count.
  • HTML is cleaned before matching, so markup inside the emphasized text does not affect the count.
  • Excessive emphasis weakens its meaning; when everything is marked important, nothing reads as important.
  • Strong formatting alone does not make a term more relevant, and this factor is a correlational signal — it relates to position within a measured result set and does not guarantee or cause a ranking.
