Your content analysis happens entirely in your browser - no data is stored or transmitted.
Keyword density refers to the percentage of times a specific keyword or phrase appears in your content compared to the total number of words. It's calculated using the formula: (Keyword Frequency / Total Words) × 100. While keyword density was once a primary factor in search engine algorithms, modern SEO focuses more on semantic relevance, content quality, and user experience.
However, understanding keyword density remains important for several reasons:
If your 1000-word article contains the keyword "digital marketing" 15 times, your keyword density would be:
(15 / 1000) × 100 = 1.5% keyword density
This falls within the generally recommended range of 1-3% for optimal SEO performance.

Paste your content into the large text area on the left side of the tool. The tool will automatically process your content and provide basic statistics like word count, character count, and reading time.

Examine the results to identify optimization opportunities. Look for keywords that are underused (density too low) or overused (density too high) and adjust your content accordingly.
While there's no magic number for perfect keyword density, SEO experts generally recommend the following guidelines:
It's crucial to understand the difference between proper keyword optimization and keyword stuffing:
| Proper Keyword Optimization | Keyword Stuffing (Avoid) |
|---|---|
| Natural keyword placement that enhances readability | Forced, repetitive keyword usage that disrupts flow |
| Keywords used in context with related terms | Exact keyword repetition without semantic variation |
| Density within recommended 1-3% range | Density above 5% that appears unnatural |
| Focus on user value and content quality | Focus solely on search engine manipulation |
Google explicitly warns against keyword stuffing in their Webmaster Guidelines. Over-optimization can result in manual actions or algorithmic penalties that significantly impact your search rankings. Focus on creating valuable, user-focused content rather than artificially inflating keyword density.

Even experienced content creators can make keyword optimization errors. Here are the most common mistakes and how to avoid them:
| Mistake | Impact | How to Avoid |
|---|---|---|
| Over-Optimization | Search penalties, poor user experience | Keep density within 1-3% range, focus on natural usage |
| Ignoring LSI Keywords | Missed semantic search opportunities | Include related terms and synonyms naturally |
| Keyword Placement Errors | Reduced relevance signals to search engines | Place keywords in titles, headings, and first paragraphs |
| Neglecting User Experience | High bounce rates, low engagement | Prioritize readability and value over keyword frequency |
| Single Keyword Focus | Missed long-tail and related keyword opportunities | Diversify keyword strategy with related terms |
Keyword density analysis is most valuable in these scenarios:
Use keyword analysis while writing to ensure optimal density and natural keyword placement. This prevents the need for major revisions later.
Analyze existing content to identify over-optimized pages that may need adjustment to avoid potential penalties.
