How to use the Keyword Density Analyzer
Paste your article or any text in the left panel. The right panel instantly shows keyword frequency and density for every significant word. Use the "Filter stop words" option to hide common words like "the", "and", "is" and focus on meaningful keywords. Adjust "Min length" to show only words above a certain character count.
The phrase analysis section shows the most frequent 2-word and 3-word combinations in your text, which is useful for identifying natural keyword phrases for SEO.
What is keyword density?
Keyword density is the percentage of times a specific word or phrase appears in a text relative to the total word count. For example, if "marketing" appears 10 times in a 500-word article, its density is 2%. Search engines use word frequency as one signal for determining topic relevance, though over-optimizing (keyword stuffing) can hurt rankings. A natural density of 1–3% is generally considered healthy for a target keyword.
Frequently asked questions
Stop words are common function words like "the", "and", "is", "in", "a", "of" that appear very frequently in English but carry little meaning on their own. Filtering them out lets you focus on the meaningful content words in your text. The filter is on by default.
There is no exact "ideal" density, but most SEO practitioners aim for 1–3% for a primary keyword. Going above 5% for any single keyword can look unnatural and may be flagged as keyword stuffing. Focus on writing naturally for your audience — search engines have become very good at understanding context.
Phrases are detected using an n-gram approach — consecutive sequences of 2 or 3 words. Stop words are removed from the beginning and end of each phrase. The most frequent combinations are shown in order of count.
