About Keyword Density Checker
The Keyword Density Checker takes any block of text you paste in and shows which single words appear most often. It counts the total words the moment you type or paste, then ranks the top keywords by frequency, listing each word with its raw count and its density percentage — how much of the whole word count that word takes up. Common stop words such as "the", "and", and "of" are stripped out, so the ranking reflects the terms that actually carry meaning rather than filler.
This is the copy-and-paste way to spot keyword stuffing, confirm your target term shows up often enough, and tighten a draft before you publish. Because it reports a simple count-and-percentage breakdown, you can eyeball whether a keyword sits in the natural 1–2% range or has been overused. It works on single words only — it does not group two- or three-word phrases — so read the numbers as a per-word signal.
There's nothing to install: it's a free, in-browser alternative to the density checkers bundled into Small SEO Tools, Semrush, and similar suites, with no account, no sign-up, and no usage limits, and no separate Chrome extension to add. Everything runs locally as you type, so your text is never uploaded to a server — paste a whole article, a client's draft, or unpublished copy and it stays entirely on your device.
Frequently asked questions
- Is the Keyword Density Checker free to use?
- Yes, it is completely free with no account, no sign-up, and no usage limits. You can check as many pieces of text as you want, as often as you like.
- Is my text uploaded or stored anywhere?
- No. All analysis happens locally in your browser using JavaScript. Your text is never sent to a server, saved, or shared, so unpublished drafts and client copy stay completely private.
- Can I just copy and paste my text in?
- Yes. Paste or type your content into the box and the counts update instantly as it lands. There is no file upload step and no button to wait on — the ranking appears the moment the text is in.
- What is a good keyword density for SEO?
- Most SEO practitioners aim for a natural range of roughly 1% to 2% for a primary keyword. There is no exact rule, but very high densities can look like keyword stuffing to search engines, so writing naturally is best.
- How do I use it to check for keyword stuffing?
- Paste your draft and look at the top-ranked words and their density percentages. If your target term is well above the natural 1–2% range, or a word repeats far more than the rest, that is a sign to reword and spread the phrasing out before publishing.
- How is keyword density calculated?
- Density is a keyword's count divided by the total number of words in your text, multiplied by 100 to get a percentage. For example, a word used 5 times in a 500-word article has a density of 1%.
- Why are words like "the" and "and" not shown?
- Common stop words are filtered out because they appear frequently in all writing and carry little meaning. Ignoring them lets the ranking surface the keywords that actually describe your content.
- Does it check keyword phrase density or only single words?
- This tool measures single-word keyword density and shows the top individual words by frequency. It does not group two- or three-word phrases, so each word is counted on its own.
- How is this different from the Small SEO Tools keyword density checker?
- It does the same core job — ranking your top words by count and density — but with no sign-up and no ads to click past. Everything runs in your browser and nothing is uploaded, which the bundled checkers in larger SEO suites usually can't promise.
- Do I need a Semrush account to check keyword density?
- No. This is a free standalone alternative to the density feature inside paid suites like Semrush. You paste your text and get the counts and percentages immediately, without logging in or paying for a plan.
- Is there a Chrome extension to install?
- No install is needed. This runs as a normal web page in any browser, so there is no separate Chrome extension to add, update, or grant permissions to — just open the page and paste your text.
- Can it check the keyword density of a whole web page or URL?
- It analyzes the text you paste in rather than crawling a live URL. To check a published page, copy its body text and paste it here, and the tool will rank the words and densities for that content.
