What keyword density should you aim for?

A density of 1–3% for your primary keyword is generally considered optimal. Below 0.5% may mean you're not covering the topic thoroughly enough. Above 4% risks keyword stuffing, which search engines penalise. Natural, reader-focused writing typically lands in the right range automatically.
