Keyword Density Checker - DigiKitApp

Calculate keyword density within a text.

When should you use this?

Use this to check how often a specific keyword appears in a text, and whether the distribution looks natural or overly repetitive.

When shouldn't you use this?

Don't artificially stuff the text with a keyword just to hit some "ideal" density percentage; modern search engines can detect keyword stuffing and lower your ranking, natural writing always comes first.

Step-by-step

Paste the body copy you want to check into the Text field. Leave out navigation, footers and other boilerplate so the numbers describe the article itself.
Type the term you are measuring into the Keyword field. A single word works, and so does a short phrase such as "credit card fees".
Click Run.
Look at how many times the term appears and what share of the text it makes up, then run the same text again with close variants of the phrase.

Example

You wrote a 600-word post about pour-over coffee for a café's website. The checker reports the phrase "pour-over coffee" 18 times, which works out to the same phrase roughly every 33 words. Read the post aloud and it will probably sound forced. Swapping some of those repeats for related terms like brewing ratio, grind size or V60 makes the text easier to read and covers the topic with a broader vocabulary, which is what a reader expects from a useful article anyway.

How is keyword density calculated?

Density = number of times the keyword appears ÷ total word count × 100. The tool lowercases both the text and the keyword, splits the text into words on whitespace and counts only exact matches. Example: the text “SEO nedir? SEO, arama motoru optimizasyonudur. SEO önemlidir” has 8 words, and for the keyword “SEO” the result is 2 matches and 25%, because “SEO,” ends with a comma and counts as a different word. Written without punctuation it would be 3 matches and 37.5%.

When reading the result

The tool counts a single word. Two-word phrases such as “search engine” are not found.
Punctuation attached to a word (comma, period, question mark, quotes) breaks the match. For a more accurate measurement, strip the punctuation from the text first.
Inflected forms (for example “kitap”, “kitabı”, “kitaplar” in Turkish) count as different words. A capital İ may also not match “i” when lowercased.
There is no exact ideal density for search engines. Write naturally instead of aiming for a high figure; repeating the same word all the time bothers readers too.

Things to keep in mind

Singular and plural forms may be counted separately. Check "filter" and "filters" one at a time if both appear in your copy.
Short texts inflate the percentage fast. Three mentions in a 150-word product blurb can look high on paper and still read fine.
A natural mention in the title, a subheading and the opening paragraph usually matters more than repeating the term throughout the body.
If two of your pages target the same keyword, measure both. Pages that are nearly identical can end up competing with each other in search results.
