How to use keyword density for SEO
Keyword density tells you which words and phrases your content actually emphasizes — which isn't always the ones you intended. Checking it helps you confirm your target keyword appears often enough to signal relevance, and catch accidental over-use that reads as keyword stuffing.
This checker ignores common stop words and lets you view single keywords or 2- and 3-word phrases so you can see your long-tail coverage. Aim for natural writing first: if the density of your main keyword is very low, work it in a few more times; if it's very high, vary your language.
Frequently asked questions
What is keyword density?
Keyword density is how often a keyword appears in your content relative to the total word count, expressed as a percentage. For example, a keyword used 5 times in a 500-word article has a density of 1%.
What is a good keyword density?
There is no exact target, but most SEOs aim for roughly 0.5%–2% for a primary keyword. Higher than that risks looking like keyword stuffing, which can hurt rankings. Focus on natural, readable writing.
What are 1, 2, and 3-word keywords?
These are n-grams. 1-word shows single keywords, while 2 and 3-word views reveal the phrases (long-tail keywords) you're actually emphasizing across the page.
