A keyword usage analyzer is an essential SEO tool that helps content creators and marketers optimize their content for search engines by analyzing keyword density, distribution, and over-optimization patterns. This tool examines how frequently keywords appear in your content, where they're positioned, and whether they're used naturally or excessively.
Keyword density—the percentage of times a keyword appears relative to total word count—is an important factor in SEO. While search engines don't use exact density thresholds as ranking factors, over-optimization (keyword stuffing) can hurt your rankings and make content feel unnatural to readers. Our free keyword usage analyzer helps you find the right balance, with recommended density ranges between 0.5% and 2% for optimal performance.
Unlike desktop software or online services that require uploads, our keyword analyzer runs entirely in your browser. Your content never leaves your device, ensuring complete privacy and security. This makes it perfect for analyzing sensitive content, confidential documents, or any material where privacy is important.
Before publishing blog posts, articles, or web pages, use the keyword analyzer to ensure your target keywords are naturally integrated throughout your content. The tool helps you identify over-optimization and suggests where to reduce keyword frequency or add synonyms for more natural writing.
Conduct SEO audits of existing content to identify keyword stuffing, missing keywords, or poor keyword distribution. The analyzer helps you understand how your content performs from an SEO perspective and provides actionable insights for improvement.
While writing content, use the keyword analyzer to check keyword density in real-time. This helps you maintain natural keyword usage throughout the writing process, ensuring your content is optimized for search engines without sacrificing readability or user experience.
Analyze competitor content to understand their keyword usage patterns. Compare keyword density, distribution, and optimization strategies to identify opportunities for improving your own content strategy and SEO performance.
Copy and paste the content you want to analyze into the content textarea. The tool supports content of any length, from short paragraphs to long-form articles (50,000+ words). Your content is processed entirely in your browser, so it never leaves your device.
Enter the keywords you want to analyze, separated by commas or newlines. You can analyze single words or multi-word phrases. For example, enter "seo tools, content optimization, keyword research" to analyze all three keywords simultaneously.
Optionally enable case-sensitive matching if you need to distinguish between uppercase and lowercase keyword occurrences. By default, the tool performs case-insensitive matching, which is suitable for most SEO analysis scenarios.
Click "Analyze" to process your content instantly. The tool will display keyword counts, density percentages, status badges (Good/Warning/Over-optimized/Missing), and distribution bars showing where keywords appear in your content. Review warnings and adjust your content accordingly. Results are automatically sorted by priority: over-optimized and missing keywords appear first.

Keyword density is the percentage of times a keyword appears in your content relative to the total word count. While exact density targets aren't a ranking factor, over-optimization (density > 2.5%) can make content feel unnatural and may trigger spam filters. Natural keyword usage typically falls between 0.5% and 2%.
The tool flags keywords as over-optimized when their density exceeds 2.5% of total words. It also detects consecutive repetition, where keywords appear too close together (within the same sentence or less than 5 words apart), which can signal unnatural writing patterns. Both factors help identify content that may need optimization.
Term distribution shows where keywords appear in your content: Start (first 25%), Middle (25-75%), and End (last 25%). Balanced distribution helps ensure keywords are naturally integrated throughout your content rather than clustered in one section, which improves readability and SEO.

Yes! Enter keywords separated by commas or newlines. The tool will analyze each keyword independently, showing count, density, distribution, and status for each. This makes it easy to optimize content for multiple target keywords simultaneously.
If a keyword is over-optimized, review your content and reduce its frequency naturally. Replace some instances with synonyms or related terms, and ensure the keyword appears naturally throughout the content rather than being forced. Aim for a density between 0.5% and 2% for best results.
