SEO Tools
Keyword Density Checker
Paste any text and instantly see how often each keyword appears. Filter stop words, set a minimum density threshold, and identify your top-ranked keywords.
How it works
Paste your content into the text area. The checker splits the text into individual words, counts each one, and calculates what percentage of the total each represents. Toggle the stop-word filter to remove common filler words and reveal the keywords that matter for SEO.
Frequently asked questions
What is keyword density?
Keyword density is the percentage of times a keyword appears in a text relative to the total word count. For example, if a word appears 5 times in a 100-word text, its density is 5%.
What is a good keyword density for SEO?
There is no universally agreed keyword density for SEO. Avoid keyword stuffing (over 3-5% for a single term). Natural writing typically produces 1-2% density for important terms.
What are stop words?
Stop words are common words like 'the', 'and', 'is' that add little SEO value. Filtering them out highlights meaningful keywords.
How is density calculated?
Density = (word count / total filtered word count) × 100. Enable the 'ignore common words' toggle to exclude stop words from the total count.
