Keyword Density Checker
Keyword density is the share of words in a text taken up by a keyword: occurrences ÷ total words × 100. This checker calculates it for your target phrase and lists the most repeated words and phrases.

Keyword Density Checker
Check keyword frequency, density, top keywords, and common phrases in your content.

Formula
Keyword density (%) = (keyword occurrences ÷ total words) × 100
Example: “image compressor” appears 3 times in a 15-word passage, so density is 3 ÷ 15 × 100 = 20%. That is far too high for real writing; it only shows the arithmetic.
How to use it
- Enter the target keyword or phrase.
- Paste your content.
- Choose whether to ignore upper/lower case and whether to exclude common stop words such as “the” and “and” from the word lists.
- Select Check Keyword Density and review the target density, top words and common 2- and 3-word phrases.
How to use the results sensibly
There is no ideal density that guarantees rankings. Use the report to catch accidental repetition, which reads badly and can look like keyword stuffing, and to make sure the topic is actually covered. Writing naturally, with related terms and clear headings, matters more than hitting a percentage.
A better way to use the report
- Read the top 2- and 3-word phrases. They should describe your topic. If filler phrases dominate, the copy may be vague.
- Look for a single phrase repeated far more than anything else. Swap some instances for pronouns or natural variations.
- Check that related terms a reader would expect actually appear. A page about compressing images that never mentions JPG, PNG or file size is probably missing useful detail.
Limitations
The checker counts exact text matches. It doesn’t understand synonyms, inflections (“compress” vs “compressing”) or meaning, and it can’t see text added by JavaScript on a live page. Paste the final visible text for the most accurate count.
Frequently asked questions
No fixed number is recommended by search engines. If a phrase feels repetitive when you read the text aloud, it’s too frequent.
The stop-word option affects the frequency lists. Check the total words shown in the results for the count used.
