How to use keyword density in 2026
Modern search engines care about topic coverage and helpfulness more than exact percentages. Use your main keyword naturally in the title, H1, first paragraph and a few headings, and include related terms and questions people search. Check length with the word counter and preview your snippet with the SERP preview tool.
