Keyword Density Checker

How to Use the Keyword Density Checker

Paste or type your content into the input box above and click "Analyze Now". The tool instantly calculates word frequency for all unigrams (single words), bigrams (two-word phrases), and trigrams (three-word phrases). Results are sorted by frequency, showing the top 20 keywords per category with their count and density percentage.

Understanding Your Results

The Keyword Density Checker provides three views of your content:

• Unigrams (1-Word): Individual words, useful for identifying primary topics and key terms.
• Bigrams (2-Word): Two-word combinations, revealing common phrases and longer keyword targets.
• Trigrams (3-Word): Three-word sequences, showing more specific topic clusters and long-tail keywords.

What About Stop Words?

The tool automatically excludes common stop words like "the", "a", "an", "is", "are", "and", "but", "or", and others. These words appear in almost all text and don't provide meaningful SEO insights. By filtering them out, you can focus on the actual keywords and content topics that matter for search rankings.

How to Use Keyword Density for SEO

• Target Keyword Optimization: Use the unigrams tab to identify your primary keyword and check its density. Aim for 1-3% density for natural-sounding content.
• Discover Related Keywords: Bigrams and trigrams reveal related keywords and phrases users might search for, helping you expand your topic coverage.
• Avoid Keyword Stuffing: If any keyword exceeds 3-4% density, you may be over-optimizing, which can hurt your SEO rankings.
• Content Gap Analysis: Compare results across multiple pages to ensure consistent topical focus and keyword distribution.

Why Keyword Density Matters for SEO

While keyword density alone doesn't guarantee high rankings, it provides valuable insights into your content's topical focus. Search engines use density as one of many signals to understand what your page is about. Balanced keyword distribution helps search engines categorize your content and match it to relevant search queries without triggering keyword stuffing penalties.

Frequently Asked Questions

What is keyword density?

Keyword density is the percentage of times a specific word or phrase appears in your text compared to the total word count. It helps identify the primary topics your content covers and is used for SEO analysis.

What are n-grams?

N-grams are sequences of words: unigrams (1 word), bigrams (2 words), and trigrams (3 words). They help identify common phrases and keyword combinations in your content.

What is a good keyword density percentage?

For SEO, aim for 1-3% keyword density for your primary keyword. Too low (under 1%) suggests your content may not be focused on that topic. Too high (over 3%) may indicate keyword stuffing, which hurts SEO.

Why does the tool exclude stop words?

Stop words (like 'the', 'a', 'is') appear in almost all text and don't provide meaningful SEO insights. Excluding them helps you focus on the actual keywords and content topics that matter for search rankings.

Can I highlight specific keywords?

Yes, enter a keyword or phrase in the optional highlight field and click Analyze. The tool will show you all instances of that keyword highlighted in your original content, plus the frequency and density stats.

Does this tool work with any language?

The tool works best with English content. For other languages, results may vary depending on how words are spaced and structured.
