Density = times used / 107 words x 100. 1 phrase is over 3%, highlighted. Two and three word phrases show only when used twice or more.

3% is an editing rule of thumb, not a ranking rule: search engines publish no ideal density. Runs in your browser, nothing is sent anywhere.

FAQ

Questions about keyword density checker

Paste your text in the box at the top of this page and type the keyword you target. The tables and the keyword count update as you type.

The times a phrase appears, divided by the total number of words, times 100. A phrase used 5 times in a 500 word text has a density of 1 percent.

Search engines publish no ideal number. Write for the reader and use the keyword where it fits. This tool flags anything over 3 percent as an editing rule of thumb, so you reread it.

Not as a target. Google's spam policies name keyword stuffing, and rankings depend on relevance and quality. Density helps you catch overuse or a keyword you forgot.

Function words such as the, and, of, to and with. They top every list and say nothing about the topic. Untick the box to include them.

Two and three word phrases show only when they appear twice or more, so the table is not filled with one-off pairs.

No. The checker runs in your browser and sends your text nowhere.

Yes. It needs no account and has no limit.
