What is keyword density?

Keyword density measures how often a target keyword or phrase appears in a piece of text, expressed as a percentage of the total word count. It is used in SEO writing to assess whether a keyword is used naturally or excessively.

Formula

Keyword density = (keyword count ÷ total words) × 100

Example: keyword appears 5 times in 500 words → 5 ÷ 500 × 100 = 1%

This tool calculates density automatically. Paste your text and enter your target keyword to get an instant result with a clear signal — from "low" through to "stuffing risk."

Keyword stuffing vs. natural optimization

✓

Natural optimization

The keyword appears where it makes sense — in the title, intro, key headings, and body — without feeling forced. Readers notice the topic, not the repetition.

!

Watch carefully (2.5–3%)

The keyword appears frequently. Not necessarily a problem, but review each use to confirm it reads naturally and adds value for the reader.

✕

Keyword stuffing (5%+)

Forcing a keyword into too many sentences hurts readability and can be a negative signal for search engines. Replace some occurrences with synonyms or related terms.

SEO best practices for keyword usage

Use the keyword naturally

Include your keyword where it fits the sentence — not forced into every paragraph. Readers and search engines both notice awkward repetition.

Include related terms

Use synonyms, related phrases, and entity terms alongside your main keyword. This signals topic depth without repeating the same word.

Cover the title and intro

Include your keyword in the page title, H1, meta description, and the first paragraph. These positions carry the most weight for relevance.

Write for the reader first

The goal is content that answers the reader's question clearly. A useful, well-written page will naturally include the right keywords.

Avoid awkward repetition

If a sentence feels odd with the keyword in it, it probably is. Replace some occurrences with "this," "it," a pronoun, or a related phrase.

Check title, headings and meta

After checking density in the body, verify your target keyword also appears in the SEO title and meta description. Use the character counter to keep your meta within the safe range.

Keyword Density FAQ

What is keyword density?
Keyword density is the percentage of times a target keyword appears in a piece of text relative to the total word count. The formula is: keyword count ÷ total words × 100. For example, if "SEO" appears 5 times in a 500-word article, the keyword density is 1%.
What is a good keyword density?
There is no single correct number, but most SEO writers aim for 1–2.5% as a natural range. Below 1% the keyword may appear too rarely; above 3–5% it may start to feel repetitive or forced. The goal is natural, readable copy — not hitting a specific percentage.
Is keyword density still important for SEO?
Keyword density alone is not a ranking factor, and Google has not relied on raw keyword counts for many years. What matters is natural, relevant usage. A page that mentions a topic naturally, uses related terms, and answers the reader's question will generally outperform one that simply repeats a keyword to hit a target.
How do I calculate keyword density?
Divide the number of times the keyword appears by the total word count, then multiply by 100. This keyword density checker does this automatically — just paste your text and enter your target keyword.
Can keyword density be too high?
Yes. Repeating a keyword too often is called keyword stuffing. It makes content harder to read and can be a negative signal for search engines. Above 3% is worth reviewing; above 5% is generally considered excessive. Always write for the reader first.
Can I check multi-word phrases?
Yes. Enter any keyword or exact phrase in the target keyword field — single words and multi-word phrases both work. The checker matches the exact phrase, case-insensitively, even when there are extra spaces or line breaks in the text.
Does this tool store my text?
No. All analysis runs locally in your browser. Your text is never sent to any server, stored, or logged. This makes the checker safe for client drafts, unpublished articles, and confidential business content.
Does Google use keyword density as a ranking factor?
Google has publicly stated it does not use raw keyword density as a ranking signal. It uses much more sophisticated natural language understanding to evaluate relevance. Focus on covering your topic naturally and thoroughly, not on hitting a density target.
