What is Keyword Density Checker?

A keyword density checker analyzes the frequency of words and phrases in your content. It calculates what percentage of your total word count is made up of specific keywords, helping you optimize content for SEO without over-stuffing or under-using important terms.

How to Use Keyword Density Checker

Paste or type your content into the large text area. Optionally enter a target keyword to check its specific density. The tool instantly shows total word count, unique words, and character count. View the frequency tables for 1-word, 2-word, and 3-word phrases sorted by count. If you entered a target keyword, its occurrences and density percentage are highlighted with a recommendation.

How Keyword Density Checker Works

The tool tokenizes your content into individual words and multi-word phrases (n-grams). It counts occurrences of each word and phrase, calculates density as a percentage of total words, and ranks them by frequency. Common stop words can be filtered out to focus on meaningful terms.

Common Use Cases

  • Check if target keywords appear enough times in your content
  • Identify keyword stuffing that could trigger search engine penalties
  • Find the most frequently used 2-word and 3-word phrases
  • Optimize existing content by adjusting keyword frequency
  • Compare keyword density across different pages or articles

Frequently Asked Questions

What is the ideal keyword density?

Most SEO experts recommend a keyword density of 1-3% for your primary keyword. Going above 3% may appear unnatural and could be flagged as keyword stuffing. Focus on writing naturally while ensuring your keyword appears in key positions like the title, first paragraph, and headings.

What is keyword stuffing?

Keyword stuffing is the practice of overloading a page with keywords in an attempt to manipulate search rankings. This includes repeating keywords unnaturally, adding hidden text, or using irrelevant keywords. Google considers this a spam technique and may penalize pages that do it.

Should I focus on keyword density or content quality?

Content quality should always come first. Write naturally for your audience and ensure your content thoroughly covers the topic. Keyword density is a guideline, not a rule. If your content naturally mentions the keyword 1-3% of the time, you are likely in good shape.

What are n-grams in content analysis?

N-grams are contiguous sequences of n words from a text. A 1-gram (unigram) is a single word, a 2-gram (bigram) is a two-word phrase, and a 3-gram (trigram) is a three-word phrase. Analyzing n-grams helps identify common phrases and topics in your content.
