About Keyword Density Checker
Keyword density is the percentage of times a keyword or phrase appears in a piece of content compared to the total word count. It was once a major ranking factor, but modern search engines (especially Google with its Hummingbird, RankBrain, and BERT updates) evaluate content semantically rather than by raw frequency. That said, density is still a useful diagnostic: too low and the topic may not be clear, too high (usually >3–4%) and it looks like keyword stuffing. A good target is usually 1–2% for primary keywords, with related terms (LSI keywords) naturally mixed in. This tool analyzes your content at the 1-gram, 2-gram, and 3-gram level so you can spot over-optimization, discover your actual topic focus, and refine your writing.
How It Works
- Paste or type your content into the text area.
- Choose the N-gram size (1 = single words, 2 = two-word phrases, 3 = three-word phrases).
- Toggle stop-word filtering to remove common filler words (the, and, of, etc.).
- See the top keywords with count, density %, and position in the text.
- Optionally export the full keyword list as CSV.

💡 Advanced Tips & Pro Insights
- ▸Google has not used keyword density as a direct ranking factor since around 2013 (Hummingbird). Modern SEO is about topical relevance, not exact-match frequency.
- ▸Aim for 1–2% for your primary keyword. Above 3% is usually a red flag. Above 5% almost always hurts.
- ▸Density matters less than coverage: use synonyms, related terms, and entity variations of your topic. Google understands "car" and "automobile" as related.
- ▸Use 2-gram and 3-gram analysis to spot phrases — many valuable SEO keywords are phrases (e.g., "content marketing", "keyword research tool").
- ▸Compare your primary keyword count to total words: 10 occurrences in 1000 words = 1% density, which is good.
- ▸For local SEO, use density to check if your city/region name appears naturally (2–4 times is usually enough).
- ▸High density of a single word often signals thin content — Google may rank a comprehensive article better than one that repeats a keyword.
Frequently Asked Questions
Is this keyword density checker free?▾

What is keyword density?▾
Keyword density is the percentage of times a keyword appears in a content compared to the total word count. Formula: (keyword occurrences / total words) × 100.
What is a good keyword density for SEO?▾
Typically 1–2% for the primary keyword. Below 0.5% may be too low. Above 3% risks looking like keyword stuffing. Google does not use density as a direct ranking factor anymore, but natural flow matters.
What are N-grams (1-gram, 2-gram, 3-gram)?▾
1-gram = single words. 2-gram = two-word phrases. 3-gram = three-word phrases. Many SEO keywords are phrases, so 2-gram and 3-gram analysis often reveals your content's actual topic.
What are stop words?▾
Stop words are common filler words like "the", "and", "of", "to", "a". They are usually ignored in keyword analysis because they do not carry topical meaning.
Does Google penalize high keyword density?▾
Google does not penalize based on density alone, but its algorithms detect unnatural repetition and low-quality content. If your content reads awkwardly because of keyword repetition, you will likely rank worse than a naturally written alternative.
Should I aim for exactly 1%?▾
No — aim for natural writing first. If you are on-topic and your main keyword appears naturally in headings, body, and conclusion, density will typically land in the 0.5–2% range on its own.
