What the Keyword Density Checker does
Keyword density is the percentage of a page's words made up by a given term or phrase — a quick signal of whether content is naturally focused or awkwardly stuffed. This checker analyzes any block of text and ranks the most frequent words and phrases by how often they appear and what share of the content they represent.
Content writers and SEOs use it to audit a draft before publishing: confirming the target topic actually shows up, spotting a phrase that has been repeated too aggressively, or finding the unexpected filler words eating up the count. Because it can analyze two- and three-word phrases, not just single words, it surfaces the multi-word terms that often matter most for search.
Using the Keyword Density Checker, step by step
- Paste your content into the input box.
- Choose a phrase length — 1, 2, or 3 words — to analyze single keywords or longer phrases.
- Adjust the options: toggle "Exclude stop words", set a minimum word length, and turn case sensitivity on or off.
- Click Analyze to see the ranked table of words or phrases with their counts and density percentages.
- Sort by count, density, or alphabetically, then Copy the results or Export CSV for your records.
Counting occurrences against total words
Density is the number of times a term appears divided by the total word count, expressed as a percentage. The tool tokenises your text, counts single words and multi-word phrases, and ranks them so you can see what the page actually emphasises rather than what you intended it to.
That gap between intention and result is the honest use for this. Writing a page about one subject and finding a different term dominating the count usually means the copy drifted, or that a navigation label or boilerplate phrase is being counted alongside the body text.
Phrase counting matters more than single words for most purposes, since search intent is expressed in phrases. A page can contain both halves of a two-word term many times without ever putting them together.
- A term appearing 12 times in a 1,200-word page has a density of 1%.
- Common function words dominate any raw count, which is why the ranking is more useful after they are set aside.
- Two-word phrases usually reveal more about a page's actual subject than its most frequent single word.
What makes this one worth using
- It analyzes one-, two-, and three-word phrases, so you can audit the longer key phrases that single-word counters miss entirely.
- A built-in stop-word filter removes 40-plus common words like "the" and "and" by default, so the ranking reflects meaningful terms — and you can switch it off when you need the raw count.
- Results export to CSV and copy as text, fitting straight into a content audit spreadsheet or a report.
- All analysis happens in your browser, so unpublished drafts are never uploaded.
Density is not a ranking factor
There is no target percentage, and the widely repeated advice to aim for somewhere between one and three percent has no basis in anything Google has published. Search engines moved past term-frequency scoring a very long time ago; modern ranking uses semantic understanding of a page's topic, so repeating a phrase to hit a ratio achieves nothing.
What it can achieve is harm. Keyword stuffing — repeating terms unnaturally, or listing variations for the sake of it — is explicitly named in Google's spam policies, and it makes copy unpleasant to read, which affects the behavioural signals that do matter.
The sensible use is diagnostic. Check whether the page mentions its subject at all in the places that carry weight — the title, the opening paragraph, a heading or two — and check whether it covers the related concepts a reader would expect. Writing comprehensively about a topic produces natural term coverage without any counting, and covering the questions readers actually ask is worth more than any density figure.
Frequently Asked Questions
What is a good keyword density?
There is no official target, but most SEO guidance suggests keeping a primary keyword in the low single digits as a percentage — roughly 1–2% — to stay natural. Far higher densities can read as keyword stuffing. Use this tool to spot terms that are over-represented rather than chasing an exact number.
What are stop words and why exclude them?
Stop words are extremely common words such as "the", "and", "is", and "to" that carry little topical meaning. Excluding them — the default here — keeps the ranking focused on words that actually describe your content. You can include them by unchecking the option.
What does phrase length do?
It sets how many consecutive words count as a single term. At length 1 you see individual words; at length 2 or 3 the tool counts two- and three-word phrases, which is how you find meaningful multi-word key phrases instead of isolated words.
Is my content sent anywhere?
No. The text is analyzed entirely in your browser with JavaScript and is never uploaded, so you can safely check drafts and unpublished pages.
