Variant Density

Definition

Variant density measures how search volume is distributed among closely related keyword variants within the same group. Since Google Keyword Planner combines close variants under a single volume figure, variant density analysis reveals which specific variant actually carries the most search demand.

Why It Matters for SEO

Choosing the strongest variant for your page title, H1 tag, and URL slug is a high-leverage on-page SEO decision. A variant with 70% of the group's volume will outperform one with only 10%, all else being equal. Without variant density data, you're guessing.
