Free Keyword Density Checker Tool

Our keyword density checker is a free SEO tool. It helps you analyze your content.

Three powerful features help you optimize for search engines:

What is Keyword Density?

Keyword density shows how often a word appears in your content.

It is calculated as a percentage of your total word count.

For example, if you write 1,000 words and use “SEO tools” 15 times, the density is 1.5%.

Why Keyword Density Matters

Search engines need to understand your topic.

Keywords help them know what your page is about.

But too many keywords can hurt your rankings.

The right balance is key:

  • Too few keywords – search engines may miss your topic
  • Too many keywords – your site may look like spam
  • Just right – your content ranks well and reads naturally

Ideal Keyword Density Levels

SEO experts recommend these density ranges:

  • Primary keyword: 1-2% of your word count
  • Secondary keywords: 0.5-1% of your word count
  • Related terms: 0.3-0.5% of your word count

Example: In a 1,000-word article:

  • Use your main keyword 10-20 times
  • Use secondary keywords 5-10 times
  • Use related terms 3-5 times

Red Flags to Watch For

Our tool color-codes your results:

  • Green (1-2%): Perfect density – this is ideal
  • Yellow (2-4%): Watch out – getting too high
  • Red (4%+): Danger – this looks like spam

If you see red, use different words and phrases instead. This keeps your content natural and reader-friendly.

Tips for Better Optimization

Use different word forms:

  • Instead of just “keyword,” use “keywords,” “keyword,” “keywording”
  • This adds variety without over-repeating

Use related terms:

  • If your keyword is “SEO tools,” also use “search optimization,” “SEO software,” “ranking tools”
  • This helps without keyword stuffing

Place keywords naturally:

  • Use keywords in your title
  • Use them in your introduction
  • Spread them throughout your content
  • Include them in your conclusion

Keep reading quality high:

  • Never sacrifice readability for keywords
  • Your visitors are humans, not robots
