What is the Script to Pause Google Ads With Low CTR?

CTR stands for click-through rate. It’s a crucial performance metric that shows ad clicks as a percentage of ad impressions. For example, if an ad is shown 1000 times and 500 people click on it, the CTR would be 50%.

A low CTR indicates that your ad is not fully optimised. It could be that your copy or creative is not compelling enough or that the ad is not targeting the right keywords.

Ad platforms also charge more to show lower-performing ads. This increases the cost-per-click and ultimately results in wasted ad spend.

The script to pause Google ads with low CTR is an easy way to ensure underperforming ads don’t eat into your budget.

This script can help improve various aspects of your campaign.
