Keyword density is the percentage of times a word or phrase appears relative to the total word count. There's no magic number, but a natural range of roughly 0.5–2% for your primary keyword is a safe guide. Modern search engines reward content that reads naturally and covers a topic thoroughly.
What is a good keyword density?
Aim for natural writing first. As a rough guide, 0.5–2% for a primary keyword is comfortable. Anything consistently above 3–4% risks looking manipulative.
