Is this keyword density checker free?

Yes, with no sign-up. Pasted text is analysed in your browser and never sent to us.

What's a good keyword density?

There isn't a target. Most natural pages land between 0.5% and 2.5% for their main phrase. Use density to spot pages that never say what they're about, or that repeat it until it reads badly.

Does keyword density affect rankings?

Not directly. Google ranks on relevance and quality, and understands synonyms. Stuffing a keyword can hurt, both with readers and with Google's spam systems.

Which words are left out?

Common stop words like the, and, of and to are left out of the phrase tables, and phrases that start or end with one are skipped. They still count towards the total word count.

Does it read navigation and footers?

No. For a URL it reads the page's main content, skipping menus, headers, footers, forms and hidden elements.

Does it work in other languages?

Yes. Word counting works in any language that separates words with spaces. The stop word list is English, so other languages will show common words in the tables.

Free keyword density checker

Is your page clearly about what you want it to rank for, or stuffed with it? Analyse any page or draft to see the words and phrases it repeats most, how often your target keyword appears, and whether it's in the places that matter: title, H1, description and opening paragraph.

Target keyword (optional)

No sign-up
Reads your live site
Tells you what to fix

How to use it

Optionally enter the keyword you want the page to rank for.
Enter a page address, or paste a draft into the second tab.
Check the target keyword card first, then scan the phrase tables for what the page actually emphasises.

What keyword density is

Keyword density is how often a word or phrase appears, as a share of all the words on a page. A phrase used 10 times in 1,000 words has a density of 1%. This checker counts exact phrase matches and divides by the total word count.

Is there an ideal keyword density?

No. Google hasn't used keyword density as a ranking target for many years; it understands synonyms, related terms and topics. Density is a diagnostic: very low can mean the page never clearly says what it's about, and very high usually reads as forced to people and to search engines.

Density	Label	What it suggests
Not used	Not used	The exact phrase never appears; the page may target something else
Under 0.5%	Light	Fine on a long page if the title, H1 and intro carry the phrase
0.5% to 2.5%	Typical	Where most naturally written pages land
Over 2.5%	Heavy	Likely repetitive; vary the wording

How the checker describes your target keyword's density. Treat these as signals to reread the page, not targets.

What matters more than density

Placement: the phrase, or a close variant, in the title, H1 and first paragraph.
Coverage: answering the related questions searchers have, which brings in the related terms naturally.
Clarity: an opening that answers the search directly, which is also what makes a page citable by AI.
The rest of the page: run the technical SEO audit to check titles, headings and indexability.
