Keyword Density Checker for Any Text

Checking how often a target keyword or phrase actually appears in a piece of content, and what other words and phrases naturally repeat throughout it, is a quick sanity check many writers still do manually, scrolling and counting by eye. This tool analyzes pasted text directly and reports exact word and phrase frequency instantly, no live URL or crawler required, useful for checking a draft before it publishes, or auditing a page that's already live by pasting its content in.

Single words versus multi-word phrases, tracked separately

A single most-frequent-word list and a most-frequent-phrase list answer genuinely different questions. Single word frequency shows which individual terms dominate a piece of content, useful for a quick check that a target topic is actually well represented. Two and three word phrase frequency, sometimes called n-grams, shows which specific multi-word phrases repeat, often more directly useful for content strategy, since real search queries and natural target keywords are usually phrases, best coffee shop, not isolated single words like coffee on their own. This tool tracks both separately, since collapsing them into one list would blur two genuinely different signals together.

Why common words are filtered from the single word list only

Without filtering, the single most frequent word in almost any piece of English writing is the, followed by a handful of similarly common filler words, technically accurate but not remotely useful for understanding what a piece of content is actually about. The ignore common words option filters these out of the single word list specifically. Phrase frequency deliberately does not apply this same filter, since removing a common word from the middle of a phrase would break its meaning entirely, best of the class losing its of would become a nonsensical best class, so phrases are always counted exactly as they naturally occur in the text.

Checking a specific target keyword directly

Entering a specific target keyword or phrase shows its exact occurrence count and density, the percentage of total words it represents, calculated directly rather than estimated. This answers a narrower, more specific question than the general frequency lists: not just what repeats most in this content, but specifically, does my actual target term appear enough, or possibly too often, confirming a piece of content genuinely covers its intended topic rather than assuming it does from memory while writing.

An honest note on how much keyword density actually matters

Keyword density as a specific numeric target, aim for exactly 2 percent, was a meaningfully bigger ranking factor in an earlier era of search, and modern search engines rely far more heavily on genuine topical relevance, natural language understanding, and overall content quality than on a specific repetition percentage. That said, this remains a genuinely useful quick sanity check for two real things: confirming a target term actually appears in the content at all, easy to accidentally forget while writing, and catching unnaturally repetitive phrasing that would read poorly to an actual human reader, regardless of any specific SEO impact. Treat the density percentage here as a useful diagnostic signal, not a target number to hit precisely.

Runs entirely in your browser

All counting and analysis happen instantly in your browser, nothing you paste is sent to a server. If you're checking a page's overall balance of visible text versus underlying markup rather than word frequency specifically, our Text-to-HTML Ratio Checker covers that related but distinct question, part of the same Technical SEO Tools collection this tool belongs to.
