What Is Keyword Density?
Keyword density is the percentage of times a specific keyword or phrase appears in a piece of text relative to the total word count. It is calculated as: Keyword Density = (Number of times keyword appears ÷ Total words) × 100. For example, if your article is 1,000 words long and the keyword "SEO" appears 15 times, its density is 1.5%.
What Is the Ideal Keyword Density for SEO?
Most SEO professionals recommend a keyword density of 1–2% for primary keywords. Google does not publish an exact ideal density, but over-optimization (keyword stuffing above 4–5%) is actively penalized. A natural, well-written article typically lands in the ideal range without deliberate effort. Use this tool to check your content before publishing and make sure your primary keyword is present but not overdone.
💡 SEO Tip: Keyword density is just one signal. Semantic relevance (using related terms and synonyms), content quality, and user engagement metrics matter far more to modern search engines than hitting a precise density number. Use this tool as a sanity check, not a hard target.
What is a good keyword density for SEO?
1–2% is widely recommended for primary keywords. Secondary keywords and LSI terms can appear less frequently. Above 3–4% risks being seen as keyword stuffing by search engines.
What are stop words?
Stop words are common words like "the", "is", "at", "which", and "on" that are filtered out because they carry no keyword significance. Excluding them gives a more meaningful density analysis of content-bearing words.
Does keyword density still matter in 2025?
It matters as a baseline check — primarily to avoid keyword stuffing. Modern SEO focuses more on topical depth, semantic coverage, and E-E-A-T (Experience, Expertise, Authority, Trustworthiness) than precise density percentages.
Can I check multi-word phrases?
Yes — use the "Check Specific Keyword" tab and type in any phrase (e.g., "keyword density" or "content marketing strategy"). The tool will find every exact occurrence of that phrase in your text.
Is my content sent to a server?
No — all analysis runs entirely in your browser using JavaScript. Your text is never sent to our servers, making it completely safe for confidential drafts, client work, and unpublished content.
