Keyword density matters for SEO

"You need to maintain a specific keyword density percentage (like 2-3%) to rank well."

Keyword density has been irrelevant for over a decade. Google uses semantic understanding and natural language processing to understand content meaning, not keyword counting. Focusing on keyword density leads to awkward, over-optimized content that reads poorly. Instead, write naturally and cover your topic comprehensively. Google understands synonyms, related concepts, and context.
