Thanks for the feedback!
Keyword Density Checker counts how often each word appears in a piece of text and shows it as a percentage of the total word count. Paste a blog post, product description or landing-page copy to see which words dominate, whether your main topic actually comes through, and whether one term has been repeated so often that the writing sounds forced.
How the percentages are calculated
When you press Analyze, the text is lowercased and punctuation is removed, except apostrophes and hyphens, so "don't" and "e-commerce" stay as single words. Every remaining word counts towards Total words. Only words of three or more letters are listed, and the top 25 are shown, most frequent first:
density = (times the word appears ÷ total words) × 100
The Unique words counter shows how many different words of three or more letters the text contains.
Worked example
Take this 47-word paragraph:
A home loan EMI depends on three things: the loan amount, the interest rate and the tenure. If the rate rises, the EMI rises too. Before you apply for a home loan, compare the EMI at two or three rates so the loan fits your monthly budget.
The tool prints one line per word in the form loan — 4x (8.51%). The top five lines are:
| Word | Count | Density |
|---|---|---|
| the | 7 | 14.89% |
| loan | 4 | 8.51% |
| emi | 3 | 6.38% |
| home | 2 | 4.26% |
| three | 2 | 4.26% |
"Loan" appears 4 times in 47 words, and 4 ÷ 47 × 100 = 8.51%. The paragraph contains 25 unique words of three or more letters. Note that "rate" (2x) and "rates" (1x) are listed separately, because the tool doesn't group plurals or other word forms.
Reading the list sensibly
- Ignore the filler words. Common words such as the, and, for and you aren't filtered out, so they usually top the list. Look past them to the first topic words.
- There's no target percentage. Google has said repeatedly that it doesn't use a keyword density figure, and repeating keywords unnaturally is listed as spam in its policies. Use the numbers to catch overuse rather than to reach a quota.
- Check the topic comes through. If a page about GST registration shows "gst" only once in 800 words while "business" and "online" dominate, the page may not clearly say what it's about.
- Look for variety. Natural writing uses related terms, like EMI, instalment, tenure and interest rate, rather than one phrase over and over.
What this checker doesn't measure
- Phrases. Only single words are counted, so "home loan" appears as separate entries for "home" and "loan".
- Two-letter terms. Words like AI, UX, 5G or "EV" are left out of the list, although they still count towards the total.
- Non-Latin scripts and accents. Only basic English letters, digits and underscores survive the clean-up, so Hindi or Tamil text is removed completely and "café" becomes "caf". This tool is not suitable for content in Indian languages.
- Where words appear. Titles, headings and the first paragraph carry more weight for readers than a mention in the footer, and the count can't tell them apart.
For a count of every word rather than the top 25 with percentages, the Word Frequency Counter lists up to 40 words, including short ones. The Word Counter gives length and reading time for the same draft.
