Keyword

content

Result

Explanation

The tool analyzes your text to show keyword frequency and density percentage, helping you maintain natural keyword distribution.

How This Tool Works

Paste your content into the input area. The tool scans your text, counts how often each word and phrase appears, and calculates the percentage relative to total words. Higher density means a term appears more frequently.

1

Input

Any text you paste—blog posts, articles, or web copy you want to analyze.

2

Processing

The tool counts word frequency and calculates density as (count / total words) x 100.

3

Output

A ranked list showing each term's frequency and density percentage.

  • Repeating phrases artificially
  • Ignoring readability for metrics — use the Readability Checker

When to Use This Tool

  • •When editing SEO content to ensure target keywords appear naturally without over-repetition that could trigger search engine penalties.
  • •When analyzing content to identify unintentional repetition that makes writing feel monotonous or stuffed with the same phrases.
  • •Before publishing blog posts and landing pages to verify content aligns with SEO strategy without sacrificing readability.

Common Mistakes

  • •

    Targeting a specific percentage

    There is no magic keyword density number. Search engines focus on content quality, not percentages.

  • •

    Repeating keywords unnaturally

    Forced repetition hurts readability and can trigger spam filters. Write naturally.

  • •

    Ignoring semantic variations

    Search engines understand synonyms. Use varied vocabulary instead of repeating the same phrase.

Frequently Asked Questions

Common questions about this tool answered.

Keyword density is the percentage of times a keyword or phrase appears in a text compared to the total word count. It's calculated as (keyword frequency / total words) × 100. For example, if a keyword appears 5 times in a 500-word text, its density is 1%.
There is no magic number. Modern search engines focus on content quality, context, and user intent rather than specific density percentages. Use this tool to check for unnatural repetition or to ensure important terms appear in your content—not to hit a target percentage.
Keyword density alone does not determine rankings. Search engines use hundreds of signals including content quality, relevance, user experience, and authority. However, analyzing keyword distribution can help you write naturally and avoid over-optimization.
Stop words are common words like 'the', 'is', 'at', 'which', and 'on' that are often filtered out in text analysis. Excluding stop words helps focus on meaningful content words that carry topical significance.
Yes. Keyword stuffing—unnaturally repeating keywords to manipulate rankings—can harm your content. If a keyword appears with unusually high frequency, consider rewriting for natural flow. This tool helps identify potential over-repetition.
