How to Use Keyword Density Checker
To check keyword density, paste your article or webpage content into the text area. The tool analyses the text and calculates how frequently each word and phrase appears, expressed as a percentage of the total word count. Results are displayed in a ranked table showing the most common terms.
The density percentage tells you whether a keyword is used too rarely (potentially under-optimised for SEO) or too frequently (potentially over-optimised, which can be penalised by search engines). Use the results to achieve a natural, balanced distribution of your target keywords.
Frequently Asked Questions
What is keyword density? expand_more
Keyword density is the percentage of times a keyword appears in a piece of text relative to the total word count. It is used in SEO to gauge whether a page is sufficiently focused on its target terms.
What is a good keyword density for SEO? expand_more
There is no single ideal density. Most SEO practitioners recommend keeping primary keywords between 0.5% and 2.5% of total words to maintain a natural reading experience. Going above 3–4% risks appearing as keyword stuffing.
Does keyword density directly affect search rankings? expand_more
Keyword density is a minor ranking signal. Modern search engines focus more on topical relevance, user intent, and content quality than on exact keyword frequency. Natural writing tends to produce appropriate density automatically.
Are stop words included in the analysis? expand_more
Common stop words (like 'the', 'and', 'is') are typically filtered out of keyword density results so that only meaningful content words are shown in the analysis.
Can this tool analyse 2 or 3-word phrases? expand_more
Yes. In addition to single-word analysis, the tool calculates density for 2-word and 3-word phrases (bigrams and trigrams), which are important for long-tail keyword optimisation.
