Keyword Density Checker

What is keyword density?

Keyword density is how often a word appears in your text as a percentage of the total word count. Paste your page copy and this tool lists the most frequent keywords with their counts and density, so you can see what your content is actually "about" in the eyes of a search engine.

How to use it

• Check that your target keyword appears naturally — not buried, not overused.
• Spot keyword stuffing — if one word is at an unnaturally high density, it reads as spam and can hurt rankings.
• Ignore common stop words (the, and, of…) to focus on meaningful terms.

FAQ

What's a "good" keyword density?

There's no magic number, and modern search engines don't reward a specific percentage. As a loose guide, a primary keyword around 1–2% reads naturally; much higher starts to look like stuffing. Write for humans first — relevance and good content matter far more than hitting a density target.

Does it count one-word keywords or phrases?

The core report counts individual words and their frequency. To gauge a multi-word phrase, look at whether its component words appear at sensible rates and read the surrounding copy, since two-word and three-word phrases matter for ranking too.

What are stop words and why are they ignored?

Stop words are extremely common words like "the," "and," "of," and "to" that carry little topical meaning. Filtering them out keeps the report focused on the terms that actually describe what your page is about.

Can high keyword density hurt my SEO?

Yes. An unnaturally high density signals keyword stuffing, which modern search engines treat as a spam pattern and can penalize. If a single term spikes well above the rest, rewrite to read naturally and use synonyms and related terms instead.

Is this tool free, and is my text private?

Yes, it is completely free with no sign-up. The analysis runs in your browser, so your text is never uploaded to a server, and it works on phones, tablets, and desktops.
