Keyword Density Checker
Analyze keyword frequency, bigrams, and trigrams from any public webpage.
What is a Keyword Density Checker?
A Keyword Density Checker is an SEO tool that scans a webpage and calculates how often each word or phrase appears in the text. The result is expressed as a percentage, showing the proportion of times a keyword is used compared to the total word count on the page.
For example, if the word “nutrition” appears 20 times on a 1,000-word page, its keyword density is 2%.
Why is Keyword Density Important?
- SEO Balance – Using your target keywords enough helps search engines understand your content.
- Avoid Over-Optimization – If a keyword appears too often (usually above 3–5%), it may look like “keyword stuffing” and hurt rankings.
- Content Insights – Density checks reveal which words and phrases your content naturally emphasizes, helping you align with search intent.
- Competitor Analysis – By running the tool on competitor pages, you can see what keywords they’re focusing on and adjust your strategy.

💡 Tips for Best Results
