About the Keyword Density Checker

The ByteTools Keyword Density Checker measures how often your keywords appear relative to the total word count. It reports the density of the top single words and, crucially, of two-word and three-word phrases (n-grams) so you can see the exact terms search engines associate with your page.

SEO writers use it to confirm a target keyword is present without over-optimising, to spot accidental keyword stuffing, and to discover which phrases dominate a draft. Each result shows the term, its count and its density percentage in a clear ranked table.

Frequently asked questions

What is a good keyword density for SEO?

There is no official target, but most SEO practitioners aim for roughly 1–2% for a primary keyword and write naturally rather than to a number. Densities much higher than that can look like keyword stuffing, which this tool helps you avoid.

How is keyword density calculated?

Density is the number of times a keyword appears divided by the total number of words, expressed as a percentage. For phrases, the tool counts how often the exact two- or three-word sequence occurs across your text.

What are 2-word and 3-word phrases (n-grams)?

N-grams are consecutive word sequences: a 2-gram is a two-word phrase like 'keyword density' and a 3-gram is three words like 'on page seo'. Checking phrase density reveals the multi-word terms your content actually emphasises.

Does the checker ignore common words?

For single-word density it filters out common stop words such as 'the' and 'and' so the ranking highlights meaningful keywords. Phrase results keep all words, because stop words are often part of natural key phrases.

Is my content uploaded when I check keyword density?

No. All calculations run in your browser with JavaScript. Nothing is transmitted or stored, so it is safe for unpublished pages and confidential client work.
