Optimal Keyword Density Thresholds (1% to 2.5%): Keyword density measures the percentage frequency of a specific word or phrase relative to the total word count of an article. SEO best practices recommend maintaining a 1% to 2.5% keyword density. Exceeding 3% risks triggering Google search penalties for keyword stuffing, while falling below 0.5% may hinder topical relevance indexing.

The analyzer automatically filters out common English stop words (the, and, for, with, is) to highlight meaningful topical keywords.
