FAQ

What density should I aim for?

1-3% for the primary keyword is the conventional target. More important than density is natural-sounding placement in titles, intros, and headers.

Does Google still care about keyword density?

Less than 10 years ago, but it's still a useful diagnostic for over- or under-optimisation.
