Frequently asked questions
What is a good keyword density?
There’s no exact target, but a main keyword around 0.5–3% reads naturally. Much higher than that risks looking like keyword stuffing, which search engines may penalise. Write for humans first.
What does “ignore common words” do?
It filters out stop words like “the”, “a”, “of” and “and” so the results focus on meaningful keywords. Phrases that mix a stop word with a real word (like “best of”) are still kept.
What are 2-word and 3-word phrases?
These are n-grams — consecutive word combinations. Analysing 2- and 3-word phrases surfaces the key phrases people actually search for, not just single words.
How do I check keyword density for SEO?
Paste your article or page copy into this free keyword density checker, pick single words or 2/3-word phrases, and it instantly lists each keyword’s frequency and density percentage — so you can see which terms you’re emphasising and whether they match your target SEO keyword.
How do I calculate keyword density percentage?
Keyword density % = number of times the keyword appears ÷ total word count × 100. This keyword density calculator does the maths automatically and lets you check a specific target keyword to see its exact occurrence count and density.
Does keyword density still matter for SEO in 2026?
Keyword density is no longer a direct ranking factor — modern search engines understand meaning and synonyms. But it's still a useful check to avoid keyword stuffing (which can hurt rankings) and to confirm your main topic is clearly present. Aim for natural writing over a specific percentage.
What is keyword stuffing and how do I avoid it?
Keyword stuffing is repeating a term unnaturally to try to manipulate rankings, which search engines penalise. This tool flags terms with an unusually high density so you can spot over-use — rewrite those passages with synonyms and natural phrasing to keep the content readable.
