Keyword Density Checker

What is Keyword Density Checker?

Keyword Density Checker is a free online tool that analyzes how often specific words and phrases appear in your text. It calculates the percentage of keyword usage compared to total word count, helping you optimize your content for search engines without overdoing it.

Why Would You Need to Check Keyword Density?

Understanding keyword density helps you write better content for both readers and search engines:

• SEO optimization: Find out if your target keywords appear enough times to rank well in search results
• Avoid keyword stuffing: Make sure you are not overusing keywords, which can hurt your rankings
• Content analysis: Discover which words dominate your text and identify opportunities for improvement
• Competitor research: Analyze competing content to understand their keyword strategy

1. Paste your text: Copy your article, blog post, or web page content into the text box on the left
2. Adjust settings: Set minimum word length and choose whether to exclude common stop words (like "the", "and", "is")
3. Click Analyze: Press the "Analyze Keywords" button to process your content
4. Review results: Check the keyword tables showing 1-word, 2-word, and 3-word phrases with their density percentages
5. Search specific keywords: Use the search box to check the density of any particular keyword you are targeting

Frequently Asked Questions

What is the ideal keyword density?

Most SEO experts recommend keeping keyword density between 1-3%. However, there is no perfect number. Focus on writing naturally and making sure your content provides value to readers.

What are stop words?

Stop words are common words like "the", "and", "is", "in", "to" that appear frequently in any text but do not carry much meaning for SEO. Excluding them gives you a clearer picture of your important keywords.

What is lexical density?

Lexical density is the ratio of unique words to total words in your text. Higher lexical density (40-60%) indicates richer vocabulary and generally more engaging content.

Can keyword density alone improve my rankings?

No, keyword density is just one of many ranking factors. Search engines also consider content quality, user experience, backlinks, page speed, and many other signals. Use this tool as part of your overall SEO strategy, not as the only metric.
