Analyze keyword frequency and density in any text or article for SEO optimization.
A keyword density checker is a free SEO tool that analyses the frequency of words and phrases in any text. It shows you which keywords appear most often and what percentage of the total word count they represent — helping writers avoid keyword stuffing and ensure their content is appropriately optimised for search engines.
Check that your target keyword appears often enough to signal topic relevance without triggering over-optimisation penalties.
Identify overused words in your writing and find where to replace repetitive terms with synonyms.
Paste a competitor's content to understand which keywords they are targeting and how they structure their optimisation.
Check that you are not over-repeating specific terms in essays or research papers.
Keyword density is the percentage of times a target keyword appears in a text relative to the total word count. Formula: (Keyword Count ÷ Total Words) × 100.
Most SEO experts recommend a keyword density of 1–2% for your primary keyword. Higher densities risk being flagged as keyword stuffing by Google.
Yes, but less than it did in the early 2010s. Google now uses semantic analysis to understand topic relevance. Natural usage of keywords and related terms is more effective than hitting an exact density target.
Common stop words (the, a, and, is, etc.) are typically excluded from keyword density analysis as they appear in all content and provide no SEO signal.
