Keyword Density Checker

What is keyword density?

Keyword density is the percentage of times a word or phrase appears in a text compared with the total number of words. If a 500-word article uses “airport taxi” 10 times, the phrase makes up 10 × 2 ÷ 500 = 4% of the words. This keyword density checker does the counting for single words, two-word phrases and three-word phrases.

How to check keyword density

1. Paste your blog post, product description or page copy into the box.
2. Keep Ignore stop words switched on to hide common words like “the”, “and” and “of”.
3. Switch between the 1 word, 2 words and 3 words tabs to see single keywords and longer phrases.
4. Check that your target keyword appears near the top, without being used far more than anything else.

What is a good keyword density for SEO?

There is no magic number. Modern search engines understand topics and synonyms, so repeating one phrase over and over does not help, and it can make your text read badly. As a rough guide, most well-ranking pages use their main keyword at around 0.5–2%, together with related words and variations. If one phrase is above 3–4%, rewrite a few sentences using synonyms.

Use the results to improve your content

• Missing keyword? If your main topic is not in the top results, mention it in your title, first paragraph and at least one heading.
• Too repetitive? Replace some repeats with synonyms or pronouns.
• Find new ideas. Two and three-word phrases often reveal long-tail keywords worth their own section.

Check the length of your text with the word counter, then write a matching title with the meta tag generator.

How keyword density is calculated

For single words, density is (times the word appears ÷ total words) × 100. For phrases, each occurrence counts for every word in the phrase, so a two-word keyword used 5 times in 500 words has a density of (5 × 2 ÷ 500) × 100 = 2%. This matches how most SEO tools report phrase density, so you can compare results.

What to look for in your results

• Your main keyword should appear in the top results, ideally in the 2-word or 3-word tab if it is a phrase.
• Related terms should appear too. A page about “airport taxi” that also mentions “fixed fare”, “meet and greet” and “flight tracking” signals topic depth.
• No single phrase should dominate. If one phrase is far above 3%, the text probably reads unnaturally.
• Unexpected words at the top can show that your content drifts off-topic.

Keyword density vs. topic coverage

Modern search engines use language models to understand meaning, so they recognise synonyms and related ideas. That is why a page can rank for a keyword it mentions only a few times. Use density as a sanity check, not a target: make sure your main topic is clearly present, then focus on answering the searcher’s question better than competing pages.

Practical workflow

1. Paste a competitor’s top-ranking article and note the phrases that stand out.
2. Paste your own draft and compare. Are you missing important sub-topics?
3. Add sections that cover the gaps, rather than repeating the main keyword.
4. Re-check that nothing is overused, then publish.

Who uses a keyword density checker?

Bloggers checking a draft before publishing, copywriters working to an SEO brief, students keeping essays on topic, and e-commerce teams reviewing product descriptions. It works with any language that uses spaces between words, including English, Spanish, French, German and Urdu written in Roman script.
