Free keyword density checker
This keyword density checker analyses your content and shows which words and phrases appear most often, with a count and density percentage for each. It works on single keywords and on 2 and 3-word phrases, so you can see your real target terms — not just isolated words.
Use it defensively, not as a target
The old SEO game of hitting a specific keyword density is dead — modern search engines read topics, context and synonyms, and reward writing that sounds human. Where density analysis still helps is as a safety check: it catches when you've accidentally repeated a term so often it reads as keyword stuffing, which can hurt rather than help. Anything flagged above roughly 3% is worth a second look.
Phrases reveal intent
Single-word counts can mislead — the word “free” appearing a lot tells you little. Switch to 2 and 3-word phrases and your genuine focus terms emerge: keyword density, online tool, free image converter. That's the view that tells you what a page is really about. Everything runs in your browser, so your draft stays private.
Frequently Asked Questions
What is keyword density?
Keyword density is how often a keyword appears in your content as a percentage of the total word count. If a 500-word article uses a keyword 10 times, its density is 2%.
What is a good keyword density?
There's no magic number, but around 1–2% for your main keyword reads naturally. This tool flags any single keyword above roughly 3%, which starts to look like keyword stuffing.
What are 2 and 3-word phrases?
These are n-grams — multi-word keyword phrases. 'keyword density' is a 2-word phrase; 'good keyword density' is a 3-word phrase. Checking phrases often reveals your real target terms better than single words.
Does keyword density still matter for SEO?
Not as a target to hit. Modern search engines understand topics and synonyms, so writing naturally matters far more. Density is best used defensively — to catch accidental over-optimisation, not to force a number.
What are stop words and why ignore them?
Stop words are common words like 'the', 'and' and 'is' that appear constantly but carry little meaning. Filtering them surfaces your meaningful keywords instead of drowning them in noise.
Is my content private?
Yes. The analysis runs entirely in your browser, so your content is never uploaded and the tool works offline.
