Your content

Target keyword (optional)

Multi-word phrases are matched in order, so “local seo” will not match “seo local”.

What this tool does not do: This analyses text you paste in. It does not fetch a live page, and it has no access to search volume or difficulty data — those require a paid data provider.

How to use this tool

Paste the content you want to analyse.
Optionally enter a target keyword to check its density specifically.
Review the top terms — one-, two- and three-word phrases are counted separately.

What is Keyword Density Checker?

Keyword density is the share of your content made up by a given term. It was a genuine ranking factor twenty years ago, which is why so much advice still fixates on hitting a percentage.

It is not one now. Modern search engines evaluate whether a page covers a topic, not how many times a string repeats. What density is still useful for is diagnosis: if your target term appears once in 1,500 words, the page probably is not clearly about it — and if it appears 60 times, the writing has almost certainly suffered.

Best practices

Do not write to a density target. Write naturally, then check whether the result reads as being about your topic.
Anything above roughly 3% for a single term is worth re-reading — it usually sounds repetitive out loud.
Look at the two- and three-word phrases; they tell you more about what the page is actually about than single words.
Include natural variations and related terms rather than repeating one exact phrase.
If your target keyword is not in the top terms at all, the page may need restructuring rather than more mentions.

Frequently asked questions

What is a good keyword density?

There is no target worth chasing. Google has no density threshold. If you write naturally about a topic, the density usually lands somewhere between 0.5% and 2.5% without any effort — and that is the point: it should be an outcome, not an input.

Can keyword stuffing hurt my rankings?

Yes. Keyword stuffing is named explicitly in Google’s spam policies. Beyond any penalty, it makes content unpleasant to read, which costs you the engagement that does matter.

Does this tool show search volume or difficulty?

No. Those come from proprietary datasets that cost money to license. This tool analyses the text you give it and nothing else — it will not invent numbers it cannot know.

Are stop words included?

Common words like "the" and "and" are filtered out of the top-terms list, because otherwise they would fill it. The total word count includes everything.
