About Keyword Density Checker
Keyword density is the share of your text made up by a given word or phrase. It was once treated as a target to hit, and that era produced a great deal of unreadable writing. Modern search engines do not reward a magic percentage, and stuffing is actively penalised — so the useful question is no longer 'am I at 2%' but 'does this page obviously look like it is about what I claim'.
That is what this tool answers. It reports what your text actually emphasises, so you can catch the two common failures: a page about image compression that never quite says 'compress images', and a page that says it eleven times in four paragraphs and reads like a robot wrote it.
Phrases matter more than single words. 'Image' tells you almost nothing; 'compress image online' tells you exactly what the page is for. Two- and three-word counts are reported separately for that reason, and phrases seen only once are filtered out because a single occurrence says nothing about emphasis.
How to check keyword density
Paste your content
Body text only. Leave out navigation and footers, which repeat across every page and would skew the counts.
Read the phrase lists first
Two- and three-word phrases describe your topic far better than single words do.
Check what is missing
The most useful finding is usually a phrase you expected to see near the top and did not.
How to read the numbers
- There is no correct percentage. Anyone quoting one is repeating advice that stopped being true a decade ago.
- Above about 5% for a single word, text almost always reads badly to a person — which is the signal that actually matters.
- Stop words like 'the' and 'of' are excluded from single-word counts, because their frequency tells you nothing about your subject.
- They are kept inside phrases, because 'how to compress' is a real phrase and 'how compress' is not.
- Short text produces unstable percentages. Under about 300 words, a single extra mention moves the figure a lot.
