Keyword Density Checker Pro
Check how often a word or phrase appears in your text with this free tool.
How the Keyword Density Checker Pro works
Use the Keyword Density Checker Pro to find out how many times a specific word or phrase appears in your content. This tool calculates the density as a percentage of your total word count.
First, paste your content into the "Your text" input field. This is the body of text you want to analyze. Next, type the specific word or phrase you want to check into the "Word or phrase to check" input field. The tool will then process your input. It counts every instance of the specified word or phrase, including overlapping matches. It also counts the total number of words in your text.
The tool displays the count of your target phrase, the total word count, and the calculated density as a percentage. This helps you understand the proportional use of your chosen term within the text. Adjust your content as needed based on these results.
Formula used
density % = (phrase count ÷ total words) × 100, words counted in phrase separately
| Symbol | Meaning |
|---|---|
| phrase count | how many times the phrase occurs, overlapping matches included |
| total words | runs of non-whitespace in the text |
| one-word phrases | also include stop words — the density is relative, not a quality judgement |
There is no magic number: Google’s own guidance is to write naturally. Older guides quote 1–2% as a ceiling — past about 3% a page reads stuffed to both readers and ranking systems, so treat 2% as a warning line rather than a target.
Inputs used: Your text, Word or phrase to check.
Worked example
Here is a worked example using the Keyword Density Checker Pro.
- Input the text: "A keyword density checker does not improve a page by itself; it shows whether your draft leans too hard on one phrase. Good density starts with natural writing — read the paragraph aloud and replace repeats with pronouns or synonyms."
- Input the phrase to check: "keyword density".
- The tool counts one instance of "keyword density". It also counts 39 total words in the text. The density is calculated as (1 ÷ 39) × 100, which equals 2.56%.
Result:
- count: 1
- totalWords: 39
- density: 5.13
