You can use CTR to evaluate the effectiveness of many different types of ads, including Google Ads and social media ads. You will need to be able to track the views and clicks that each ad receives during a certain period of time.  For example, let’s say that you’re running a Google Ad that received 40,000 impressions and 600 clicks in a one-week period. Your CTR for that ad would be 1.5%. Revising your ad copy, reworking your target search terms, and even changing up the ad design could potentially help increase your CTR.
