Keyword Density Checker
Check keyword density and frequency in your content. Optimize for SEO.
About the Keyword Density Checker
The Keyword Density Checker is a free SEO tool that analyses any block of text (article, blog post, product description or landing page copy) and shows how frequently each word or phrase appears, expressed both as raw count and as percentage of total words. Search engines look at keyword density as one signal of topical relevance, so understanding yours is a first step to writing pages that rank. The tool detects 1-word, 2-word and 3-word phrases, sorts them from most to least frequent, and highlights terms that may be over-optimised.
Keyword density is the number of times a target keyword appears in a text divided by the total number of words, multiplied by 100. A density of about 1-2% is considered natural; densities above 3-4% start looking like keyword stuffing, which modern algorithms penalise. Analysing density before publishing helps you strike the balance between clear topic signals and readable, human-first prose.
Key Features of Our Keyword Density Checker
Every feature below is built for accuracy, speed and privacy — the tool runs entirely in your browser, so nothing you type is uploaded to a server or shared with third parties.
Single-word density
Ranks every individual word by frequency, ignoring common stop-words that would otherwise dominate the list.
Two- and three-word phrases
Detects bigrams and trigrams so you can see how often you use meaningful noun phrases like "digital marketing".
Percentage & raw count
Shows both metrics per keyword so you can benchmark against target density ranges.
Instant analysis
Paste and analyse — no waiting on a slow server.
Total-word summary
Automatically reports overall word count so you know your sample size is meaningful.
Fully private
Analysis runs entirely client-side. Your unpublished copy never leaves your device.

- 3

- 5
Edit and re-run
Add or remove instances of a keyword until you hit the density and readability you want.
Why Choose Our Keyword Density Checker?
Diagnose keyword stuffing
If a keyword is above 3% density, you are risking a spam signal — the checker flags it before you publish.
Discover missed opportunities
Sometimes your target keyword is at 0.4%; a quick edit to bring it near 1% can lift ranking without hurting readability.
Verify search intent alignment
The top-frequency phrases should match your target search intent. If they do not, the article may drift off-topic.
Track semantic coverage
A rich cluster of related bigrams / trigrams signals topical depth to modern semantic algorithms.
Common Use Cases
The Keyword Density Checker is trusted by students, writers, marketers, developers and everyday users worldwide. Here are some of the most common scenarios where it saves time and delivers reliable results.
SEO copywriters
Optimise every article to target density ranges before handing off to editors and clients.
Bloggers
Verify a post is not accidentally repeating the primary keyword in every paragraph.
Agencies
Audit dozens of client pages quickly and produce clear, quantitative optimisation recommendations.
E-commerce teams
Ensure product descriptions include target search terms without descending into spam.
Content editors
Detect over-used clichés and repeated phrases that hurt style.
Best Practices & Tips
Target 1-2% primary density
Aim for the primary keyword to appear at roughly 1-2% of total words for a natural, safe density.
Prioritise topical breadth
A page ranks better with many related terms at low density than with one keyword crammed everywhere.
Write for humans first
If a passage feels stiff or repetitive, it probably is — reduce density until it reads smoothly.
Diversify with synonyms
Google understands semantic variants. Rotate synonyms and closely related phrases to enrich the topic model.
Frequently Asked Questions
What is a good keyword density?
Somewhere between 1% and 2% for a primary keyword. Secondary keywords typically sit at 0.5-1%.
Does higher density mean better ranking?
No. Beyond about 2-3%, keyword stuffing risks a manual penalty or algorithmic downgrade.
Are stop-words counted?
Common stop-words (the, a, and, of, to, in, is …) are filtered from the density list so meaningful terms dominate the report.
Does this work for non-English content?
Yes. The tokeniser splits on Unicode whitespace, so Urdu, Arabic, Hindi, Spanish and other languages are handled.
Do you count phrases or only single words?
Both — the tool reports single words, bigrams and trigrams so you can see phrase-level density.
Is my text sent anywhere?
No. Analysis is 100% client-side JavaScript. Nothing is uploaded.
Can density alone rank a page?
No. Ranking depends on relevance, links, EEAT, page experience and more. Density is one small signal among many.
Should I match a competitor’s density?
Directional comparison is useful, but do not copy densities blindly — competitors sometimes rank despite poor density, not because of it.

Privacy, Security & Trust
The Keyword Density Checker is built with a privacy-first philosophy. Every calculation, encoding and transformation runs entirely inside your web browser using standard JavaScript APIs — nothing you type, paste or upload is transmitted to our servers, logged, cached or shared with any third party. You can verify this yourself by opening your browser's developer tools and watching the Network tab while you use the tool: you will see zero outbound requests for the actual computation.
This client-side architecture matters most when you are working with sensitive text — an unpublished blog draft, a legal notice under embargo, an internal meta description, or a password you are about to set. On many competing sites, similar tools quietly send every keystroke to their servers for "processing", which becomes a real leak vector. Ours does not, and it never will.
The tool is completely free with no daily quotas, no watermarks and no forced sign-up. It works on desktop and mobile browsers, on slow and fast connections, and continues to function offline once the page has loaded. All source code, formulas and character tables used by the tool are standard, well-documented and independently verifiable — which is essential for anything you plan to use for legal, medical, financial or educational purposes.
