Keyword Density Analyzer

This tool utilizes a local JavaScript parsing engine to deconstruct your text into measurable SEO metrics. When evaluating content, search engine crawlers don't just look at single words; they look at groupings of words to understand semantic context.

Understanding N-Grams:

• 1-Grams: Single words. Good for general topic targeting.
• 2-Grams (Bigrams): Two-word phrases (e.g., "digital marketing"). Essential for specific context.
• 3-Grams (Trigrams): Three-word phrases (e.g., "digital marketing agency"). Often represents high-intent, \"long-tail\" search queries.

The Stop-Word Filter: By default, this tool filters out the top 100 most common English "stop words" (like the, and, of, to, a). While these words make up 50% of human speech, they carry almost zero SEO weight. Filtering them out allows you to see the true semantic density of your content.

Zero-Trace Execution: Analyzing unreleased client drafts or proprietary articles on third-party servers poses a massive data leak risk. This tool executes 100% client-side. The Regex tokenization happens in your device's RAM, and the data is purged the moment you close the tab.
