How the keyword density checker works
Keyword density measures how frequently a phrase appears relative to the total word count:
Density = (Keyword occurrences × words in keyword) ÷ Total words × 100
Step-by-step guide
- Enter the exact keyword or phrase you're checking for.
- Paste your article or page content.
- Read the occurrence count and density percentage.
Using this responsibly
Treat this as a sanity check, not a target to optimize toward. Modern search engines prioritize content that thoroughly and naturally covers a topic — including related terms and synonyms — over content mechanically repeating one exact phrase.
Frequently asked questions
There's no verified optimal percentage — search engines have moved well beyond simple keyword-density scoring toward understanding context and intent. A commonly cited rough guideline is roughly 1–2%, but writing naturally for readers matters far more than hitting a specific number.
Yes — unnaturally repeating a keyword ('keyword stuffing') reads poorly to users and can be flagged negatively by search engines. If a percentage feels high enough to sound repetitive when read aloud, it probably is.
No — matching ignores case, so 'SEO' and 'seo' are counted as the same keyword occurrence.
