How the keyword counter works
Paste or type your text into the box above. The tool instantly counts every word, then ranks your most-used keywords and calculates each one's density — the percentage of your total word count that the keyword represents. Common filler words ("the", "and", "is") are excluded, so you see the keywords that actually matter.
What is a good keyword density?
There's no magic number, but a natural keyword density of about 1–2% is the common rule of thumb for SEO. Use your target keyword enough that the topic is clear, without repeating it so much that it reads unnaturally. If a single keyword climbs much above ~3%, that's usually a sign to rewrite for variety — search engines flag over-optimization as "keyword stuffing."
| Keyword density | What it usually means |
|---|---|
| Under 0.5% | Keyword may be too sparse — topic unclear to search engines |
| 1–2% | Natural and SEO-friendly for most content |
| Over 3% | Risk of keyword stuffing — rewrite for variety |

Frequently asked questions
What is a keyword counter?
A keyword counter is a free tool that counts how many times each word (keyword) appears in your text and shows its keyword density — the percentage of the total word count that each keyword represents. Paste your text above and the counts update instantly.
What is keyword density and what is a good percentage?
Keyword density is how often a keyword appears relative to the total number of words, shown as a percentage. For SEO, a natural keyword density of roughly 1–2% is generally considered safe. Going much higher risks looking like "keyword stuffing," which search engines penalize.
How is a keyword counter different from a word counter?
A word counter tells you the total number of words and characters. A keyword counter goes further and breaks down how many times each individual keyword appears and its density — useful for SEO, essays, and checking for repetition.
Is this keyword counter free and private?
Yes. It is 100% free with no sign-up and no limits. All analysis runs entirely in your browser — your text is never uploaded to a server, stored, or used for anything.
How do I use the keyword counter for SEO?
Paste your article, check that your target keyword sits around 1–2% density, and make sure you are not over-using any single phrase. The tool also surfaces your most frequent keywords so you can spot unintentional repetition.
