// Why it matters
Density is a signal, not a target.
Keyword density used to be something people gamed. Today it is best used as a diagnostic: it tells you what a page is actually about, whether you have drifted off-topic, and whether you are stuffing a phrase so hard it reads as spam. Modern engines reward natural, comprehensive coverage of a topic, not a magic percentage.
Use this to sanity-check a draft. For content genuinely built around entities and topics rather than keyword counts, that is the modern approach we take.
Beyond keyword counting.
We build content around topics and entities, the way engines actually think now.
