Ad fatigue happens when people see the same ad so many times that they stop paying attention to it. They scroll past it without reading because it no longer feels new or interesting. In paid search, this can cause your click rate to drop even though your ad is still showing. Marketers deal with this by rotating different versions of their ads regularly, changing the headline, the description, or the call to action so it feels fresh. Refreshing your ads every few weeks helps keep performance steady. Have you noticed ad fatigue affecting your campaigns?
