What is Keyword Density Checker?
You're guessing whether your keyword shows up enough or too much. Over-optimization gets penalized; under-optimization fails to rank.
Paste your article and get a clean density table back.
If you're auditing competitors, you match the natural distribution already ranking. If you're drafting content, you hit the 1-2% sweet spot. If you're optimizing existing pages, you spot under-keyworded sections fast.

Common questions
What's a safe density range?
1-2% for primary keywords. Above 3-4% risks over-optimization filters.
Tip: Match competitor density on page one rather than chasing a fixed target.
Does it count synonyms together?
No, exact matches only. Semantic SEO tools handle variations.
Tip: Manually sum related terms for combined density.
Are stop words filtered?
Yes, 'the' and 'and' are excluded so real keywords surface.
Tip: Density numbers exclude stop-word noise.
Should I include title and meta?
Body usually checked alone. Some tools include headings.
Tip: Run body, then body+title separately.
