Keyword Density FAQ: Questions People Actually Ask

**What is keyword density, in plain terms?**
Keyword density stopped being a meaningful ranking factor over a decade ago, but the underlying question it's a rough proxy for — does this page clearly cover its topic — very much still matters.

**How often should this be checked?**
Regularly, not just once. Repeating the exact-match keyword so often that the page becomes unpleasant or robotic to actually read. Set a recurring reminder rather than trusting memory.

**What's the most common mistake here?**
Chasing a specific density percentage as if it were a ranking algorithm input — modern search engines use semantic understanding, not word counting.

**Does this actually affect rankings, or is it just best practice?**
It's rarely a single ranking factor on its own, but it affects whether search engines and users can do what you actually need them to do — which shows up in rankings indirectly, often more than any one direct factor would.

**What's the fastest way to check this on an existing site?**
Keyword Density Checker — paste your URL in and it does the check directly, no setup.
