How to use the Keyword Density Checker
- 1
Enter the target keyword you want to rank for.
- 2
Paste your article, blog post, or page copy.
- 3
Review word count, keyword count, and density percentage.
Interpreting density scores
A density of 1-2% for your primary keyword is a common target for blog posts. Zero percent may mean you forgot the keyword; above 3% risks looking like spam.
Use variations and related terms instead of repeating the exact phrase. Modern SEO rewards topical coverage over exact-match repetition.
Pro tips
- Check density after editing, not before — final drafts differ from outlines.
- Include keywords in H1, first paragraph, and one subheading when natural.
