Keyword Density Checker
Short answer
Analyze keyword frequency and density across your page content.
What it does not do: It counts all body text, navigation and footer included, and cannot judge relevance; there is no ideal density, so treat the warning as a hint.
What It Does
Analyzes the text on your page and computes 1-, 2-, and 3-word phrase frequencies as a percentage of total content. Returns the top phrases grouped by length, plus an over-optimization warning when your single most-repeated word makes up an unusually large share of the text.
Why It Matters
Keyword density is not a ranking factor, and repeating a word too often reads badly and can look like keyword stuffing, which Google's spam policies cover. Density is still useful for one thing: it shows what a page actually emphasizes, so you can spot a gap between your target topic and the words you use most.
How It Works
-
Enter your page URL or paste raw text
-
We extract the page text and tokenize it into 1-, 2-, 3-word phrases
-
Count occurrences and compute density % per phrase
-
Return a sorted table and flag it if your single most-repeated word looks over-optimized
Sample input + output
url: https://rankproof.eu/tools keyword: "rankproof"
primary: "rankproof" occurrences: 31 / 1,847 words = 1.7% OK in <title>: 1 in <h1>: 1 in <h2>: 4 in body text: 21 in alt text: 4 stuffing risk: low (target ≤ 3%) OK

Quick visual of any URL's topical focus — useful for competitive content analysis.
Frequently Asked Questions
- What's the ideal keyword density?
- There is no ideal number. This tool warns when your most-repeated word passes 4% of the text and marks it as over-optimized above 6%. Write naturally and use the list to check focus.
- Is keyword density still a ranking factor?
- Not directly. Google weighs how important a term is in context and recognises the entities behind it. But density is still a useful sanity check for content focus.
- What about LSI keywords?
- LSI is a marketing term, not a real Google factor. Use related-keywords analysis to find topically associated terms.
- Should I aim for exact keyword match?
- No. Natural variation (singular and plural, synonyms, related terms) reads better, and Google understands related wording.
- Does it count navigation and footer text?
- Yes. It reads all text in the page body except script and style tags, so navigation, footer links and text hidden with CSS can skew the results on pages with little content.
