Most SEO guidelines recommend maintaining primary keyword density between 1.0% and 2.5% to ensure strong topical relevance without triggering search engine keyword stuffing penalties.

What is lexical diversity in text analysis?

Lexical diversity (Type-Token Ratio) measures the proportion of unique words relative to total words. Higher percentages indicate a rich, varied vocabulary.

What are stop words?
