Keyword Density Checker

What is Keyword Density?

Keyword density refers to the percentage of times a specific keyword or phrase appears in a text block compared to the total number of words. For example, if a 100-word article uses the word "SEO" 3 times, the keyword density is 3%.

Why is this checker important for SEO?

In the early days of SEO, webmasters would stuff keywords into their content to rank higher. Today, Google's algorithms penalize keyword stuffing. Maintaining a natural keyword density (usually considered between 1% to 2.5%) helps search engines understand what your page is about without triggering spam filters. Our tool helps you identify overused words so you can replace them with synonyms (LSI keywords).

How to Use the Free Keyword Density Analyzer?

1. Paste your text: Copy your draft from Word, Google Docs, or WordPress and paste it into the text box.
2. Instant Analysis: The tool instantly counts the words and calculates frequencies using JavaScript directly in your browser.
3. Check N-Grams: Use the tabs to switch between single words, 2-word phrases (bigrams), and 3-word phrases (trigrams). This helps identify if you are overusing specific long-tail keywords.
4. Optimize: If a keyword shows a red warning or a very high percentage, consider editing your text to read more naturally.
