About this tool
Analyze keyword density in your content with our free keyword density checker. Enter your text and target keyword to see keyword frequency, density percentage, and distribution throughout your content. Essential for SEO professionals, content writers, and marketers who want to optimize content without keyword stuffing.
Keyword density is the percentage of times a keyword appears in your content compared to total words. While there's no "perfect" density (Google's algorithms are sophisticated), most SEO experts recommend 1-2% for the main keyword and 0.5-1% for related keywords. Our tool helps you stay in the optimal range for natural, SEO-friendly content.
The tool analyzes both single keywords and phrases (1-3 words), shows total occurrences, calculates density percentage, and identifies the top 10 most frequently used words in your content. This comprehensive analysis helps you ensure your target keywords appear enough for SEO without over-optimization that could trigger Google penalties.
All keyword analysis happens in your browser with complete privacy - your content never leaves your device. Perfect for analyzing blog posts, product descriptions, landing pages, or any web content before publishing. Works on all devices and can be used offline.

1,500-word blog post targeting "digital marketing"
Total words: 1,500. "digital marketing" appears 18 times (1.2% density). Optimal! Related terms: "marketing" (45 times), "digital" (30 times), "strategy" (22 times). Recommended: Add 1-2 more mentions for emphasis.
Product Description Optimization

Total words: 250. "wireless earbuds" appears 7 times (2.8% density). Warning: Slightly high! Reduce to 4-5 mentions (1.6-2.0%) for more natural flow. Current: borderline keyword stuffing.
Landing Page Analysis
800-word landing page targeting "SEO services"
Total words: 800. "SEO services" appears 10 times (1.25% density). Perfect! "SEO" alone: 28 times (3.5%). "services" alone: 18 times (2.25%). Well-distributed throughout content.

FAQs
What is keyword density and why does it matter?
Keyword density is the percentage of times your target keyword appears in content compared to total word count. For example, if "SEO tools" appears 20 times in a 1,000-word article, the density is 2%. It matters because Google uses keywords to understand content topics, but excessive density (keyword stuffing) can trigger penalties. Aim for 1-2% for main keywords.
What is the ideal keyword density for SEO?
Most SEO experts recommend 1-2% density for your primary keyword and 0.5-1% for related keywords. However, there's no magic number - Google's algorithms consider context, semantics, and user intent, not just keyword frequency. Focus on writing naturally for humans first, then check density to ensure adequate (but not excessive) keyword usage.
What is keyword stuffing and how do I avoid it?
Keyword stuffing is the practice of overusing keywords to manipulate search rankings, often resulting in unnatural, repetitive text. Google penalizes keyword stuffing with lower rankings or removal from results. Avoid it by: 1) Keeping keyword density under 3%, 2) Using synonyms and related terms, 3) Writing naturally for readers first, 4) Using our tool to verify density before publishing.
Should I check density for single words or phrases?
Check both! Single-word keywords (like "marketing") are often too broad. Phrase keywords (like "digital marketing strategy") are more specific and valuable for SEO. Check your main keyword phrase (2-3 words) plus important single keywords. Our tool analyzes both automatically.
How many times should I use my keyword in a 1000-word article?
For a 1,000-word article, using your primary keyword 10-20 times results in 1-2% density, which is the recommended range. However, prioritize natural flow over hitting exact numbers. It's better to have 8 natural mentions than 20 forced ones. Use variations and related terms to avoid repetition.
Does keyword density include variations and synonyms?
Our tool counts exact matches only. However, Google's algorithm understands synonyms and variations (like "automobile" and "car"). When optimizing content, use a mix of your exact keyword, variations, and semantically related terms. This creates more natural content while maintaining topical relevance.
Can keyword density be too low?
Yes! If your target keyword appears too rarely (under 0.5% density), search engines may not recognize it as a main topic. For a 2,000-word article, under 10 mentions (0.5%) might be too low. However, this depends on context - if you use many related terms and synonyms, lower exact-match density is fine.
Should meta descriptions have high keyword density?
Meta descriptions are short (150-160 chars), so keyword density will be higher. This is acceptable and even beneficial - including your keyword 1-2 times in a meta description ensures it's bolded in search results when users search that term. Just ensure the description reads naturally.
