Keyword density is the percentage of a text’s total words represented by a specific keyword or phrase. A keyword density checker makes this calculation quickly instead of requiring you to count every occurrence manually.

For example, if a 1,000-word article contains a target phrase 15 times, its density is 1.5%. This number is useful for reviewing repetition, but there is no single percentage that guarantees better search rankings. Content should remain natural and useful to readers.

A keyword density checker can help identify unusually repeated terms before you publish an article or webpage. It can also confirm that an important phrase is actually present in your draft and show repeated wording that may be difficult to notice during normal reading.

Common words such as “the”, “is”, “and”, “of”, and “to” appear naturally throughout English content. When stop-word exclusion is enabled, these common terms are removed from the filtered analysis. Because the number of words being analyzed changes, the displayed results can also change.

N-grams are sequences of words found inside your text. A single word is a 1-gram, a two-word combination is a 2-gram, a three-word combination is a 3-gram, and a four-word combination is a 4-gram.

This tool analyzes up to four-word combinations, making it easier to find phrases that are repeatedly used in an article. Reviewing N-grams can be particularly useful when editing longer content because repeated phrases are not always obvious while reading the complete draft.

There is no universal keyword-density percentage that guarantees a higher Google ranking. A keyword density checker is most useful for understanding how often terms appear and identifying possible overuse or underuse.

For an internal writing workflow, you may choose a reasonable range for a primary phrase, but it should remain an editorial guideline rather than a ranking rule. Natural language, useful information, search intent, and complete topic coverage are more important than repeating the same keyword just to reach a particular number.

The analysis is performed directly in your browser using client-side processing. The tool does not require an API key to perform its keyword density calculations. This allows you to analyze drafts, articles, and website copy directly in your browser.

There is no universal percentage that guarantees better rankings. Use the measurement to identify unusual repetition and keep your wording natural rather than writing solely for a target percentage.

Yes. You can enter multi-word phrases in the keyword field, separated by commas, and check their occurrences and density.

The analysis shows frequently occurring 1-word, 2-word, 3-word, and 4-word combinations found in your text. This can help you identify repeated phrases and common wording.

No. The keyword density analysis is performed directly in your browser, so an API key is not required.

Yes. You can analyze blog posts, articles, landing-page copy, drafts, and other written content by pasting the text into the tool.

Excluding common stop words changes the filtered text and its word count. As a result, the calculated percentages and frequency results can also change.
