Key Takeaways


📊 What is Keyword Density

Keyword density refers to how often a keyword appears in your content compared to the total number of words.

It is usually expressed as a percentage:

  • 1–2% = Natural and SEO-friendly
  • Above 3% = Risk of keyword stuffing
  • Below 0.5% = Weak keyword relevance

Understanding this balance is critical for ranking well on search engines.
