Keyword Density Checker
Analyse your page copy and discover the top keywords by frequency and density. Free, instant, runs entirely in your browser.
What is keyword density and why does it matter?
Keyword density measures how often a word appears in your copy as a proportion of the total word count. Search engines use term frequency as one of many signals to understand what a page is about, making density analysis a useful sanity-check during on-page SEO audits.
How to use the Keyword Density Checker
- Paste your article, landing page or meta description into the text area.
- The tool instantly tokenises the text, strips punctuation and groups words by frequency.
- Review the table — word, count and density % — to see which terms dominate.
- Click Copy report to capture a plain-text summary for your notes or team.
What the analyser does
Every word is lower-cased and stripped of punctuation, then short stop-fragments under three
characters are ignored so common noise like "a", "of" and "to" do not pollute the results.
The top twenty keywords by raw count are displayed, each with a density percentage calculated
as count ÷ total words × 100.
Common use cases
- Content audits — identify over-optimised pages before a Google core update.
- Draft review — confirm your primary keyword appears enough times to be meaningful.
- Competitor analysis — paste a rival's page copy and surface their focus terms.
Frequently Asked Questions
What is keyword density?↓
Keyword density is the percentage of times a specific word appears in a piece of text relative to the total word count. For example, if "SEO" appears 5 times in a 100-word article, its keyword density is 5%. It is a classic on-page signal that helps search engines understand the main topic of a page.
What keyword density should I aim for?↓
There is no magic number. Most SEO practitioners consider 1–3% a healthy range for a primary keyword — enough to signal relevance without tipping into keyword stuffing. Focus on natural, reader-friendly writing first; use this tool to spot unintentional over-repetition rather than to hit a precise target.
Does my text get sent to a server?↓
No. The entire analysis runs locally in your browser using JavaScript. Your copy is never transmitted to any server, stored in a database, or logged anywhere. This makes the tool safe to use with unpublished drafts or confidential content.
