Why analyze keyword density?
Too many repetitions (keyword stuffing) triggers algorithmic penalties. Too few, and Google doesn't understand your page's main topic. Density analysis helps find the right balance.
Since Helpful Content updates, Google prioritizes content written for humans — but with clear semantic structure. Density remains a useful signal for framing your writing.
What density to aim for?
Current SEO consensus:
- Primary keyword: 1-2.5% of total text.
- Semantic variants (LSI): up to 5% cumulative density.
- Beyond 4% for a single keyword, over-optimization risk increases.
Frequently asked questions
