Keyword Density Checker

No, you do not need to register or log in. The tool is completely free and accessible to everyone instantly.

All text processing is performed locally in your web browser, so your content is never uploaded to a server. Nothing you paste leaves this tab.

Once the webpage is fully loaded, the calculation function works perfectly without an active internet connection.

There is no strict limit on the amount of text. The tool sets no fixed cap of its own; how much text it analyzes comfortably depends on your device memory.

The keyword density report works on any language, since it simply counts space-separated words and looks for your keyword as typed. The automatic Top keywords report is more limited: it only recognizes Latin letters and digits, so text written in another script (or heavy accents) will produce an empty list there.

A word frequency counter simply lists raw counts for every repeated word. This tool lets you focus on one specific keyword or phrase of your choice, and when you leave that field empty it also produces a Top keywords report of its own.

You paste your text and optionally enter one keyword or phrase in its dedicated field; the tool then produces its Density report in the output area. With no keyword entered, it instead returns a Top keywords list built from words longer than three characters.

The most common use case is for SEO professionals who need to optimize on-page content to achieve the ideal keyword density for search engine rankings.

Instead of tracking one term, the tool produces a Top keywords report listing your most frequently repeated words. Only words longer than three characters are included, so very common short words are skipped automatically.

No. Matching is case-insensitive and includes partial hits, so searching for "cat" would also count "catalog" and "copycat". If your keyword can appear inside longer words, keep that in mind when reading the count.

You can enter a phrase such as "best running shoes" and the report counts each time that exact sequence appears. The word total used for the percentage includes every word in your text, even the words that are part of the phrase itself, which nudges phrase densities slightly lower.
