To know if your display ads are working, you need to track what people do after they see or click your ad. One way is by setting up conversion tracking, which shows if someone made a purchase or took the action you wanted after seeing your ad. You can also check your sales numbers before and after running ads to see if there’s a clear difference. Some people use tools like Google Analytics or a tracking pixel to follow how users behave from the ad click to the final sale. It’s also helpful to compare different ad creatives and placements to see which ones bring better results. What’s been your experience with tracking results?
