Keyword Density Checker — Analyze Content Keyword Frequency
This free keyword density checker analyses how often your target terms appear in a piece of content, as a percentage of total words. Keyword density — calculated as keyword occurrences divided by total words — was an early ranking signal and remains a useful editing check for whether a page is clearly about its topic. There is no magic percentage; an unnaturally high figure signals keyword stuffing, which search engines penalise.

What is keyword density?
Keyword density is the percentage of times a target keyword appears in a piece of content relative to the total word count. Formula: (keyword count ÷ total words) × 100. A 1,000-word article mentioning "EMI calculator" 10 times has a 1% keyword density for that term.
There is no universally "correct" keyword density. Google has explicitly stated it doesn't use keyword density as a ranking factor and that keyword stuffing — excessive repetition intended to manipulate rankings — actively harms rankings. A density of 1–3% is generally considered natural for a primary keyword. More important than density is semantic coverage: using related terms, synonyms, and topic-relevant vocabulary that signals comprehensive coverage of a subject. Use this tool to identify terms that appear far more than expected (potential over-optimisation) or check competitor content to understand how they naturally cover a topic.
