Frequently Asked Questions
What is keyword density and why does it matter?
Keyword density is the percentage of times a target keyword appears in text relative to total word count. For example, 5 occurrences in 100 words = 5% density. It matters for SEO because search engines use it to understand content relevance, but over-optimization (>3%) can trigger penalties.
What is the ideal keyword density for SEO?
The ideal range is 1-2% for primary keywords. Below 1% may miss ranking opportunities; above 3% risks keyword stuffing penalties. Modern SEO focuses on natural language and semantic variations rather than exact density targets.
How do I interpret the color-coded results?
Green (<1%) = safe but low, Blue (1-2%) = optimal SEO range, Yellow (2-3%) = caution zone, Red (>3%) = over-optimization risk. Use these indicators to adjust content before publishing.
What are the top 20 words used for?
The top words list reveals your content's natural focus and helps identify unintentional repetition. Use it to discover secondary keywords, check for filler words, or ensure topic coverage aligns with your SEO strategy.
Can I analyze multiple keywords at once?
Yes! Enter comma-separated keywords (e.g., 'seo, marketing, content') to track multiple terms simultaneously. Each gets individual density calculations, occurrence counts, and color-coded warnings for comprehensive analysis.
Should I remove common words from analysis?
The tool includes all words in top frequency. Common words (the, and, is) naturally rank high but don't affect SEO. Focus on content-specific words in the top 20 for meaningful optimization insights.
