Here’s how I read these two lines. They don’t show how many people search, only when interest rose and fell. Worldwide, it peaked in February 2025 and sits at 49 now, lower than a year ago. In the US it’s lower than a year ago, and the Google Ads numbers below tell the same story. When you see a sharp spike, think news story, not new customers. The baseline between the spikes is the demand I actually care about.

This is the number I’d plan with: September 2026 had 12,100 US searches, 46% fewer than in October 2025. Google Ads rounds these figures into steps, so a small move from one month to the next usually means nothing.
