Keyword Density Analyzer

The Keyword Density Analyzer breaks any block of text into its most-used single words, two-word and three-word phrases, then shows how often each appears and what percentage of the total it represents. It's the fastest way to see what a page is really "about" in the eyes of a search engine.

Density is no longer a ranking factor you optimise to a magic number — but lopsided density is still a useful warning light. If one keyword dominates unnaturally, you risk reading as spam; if your target term barely appears, the page may not be clearly on-topic. This tool gives you that signal in seconds, entirely in your browser, with an optional stop-word filter so common words like "the" and "and" don't drown out the terms that matter.
