If a display campaign isn’t doing well, the first thing to check is where your ads are showing. You might be spending money on websites or placements that don’t match your offer. Then look at your click-through rate. If not many people are clicking, your banner might need better images or a stronger message. Also check the landing page. Even if people click, they might leave if the page is slow or confusing. You can test different banners and pages to see what works better. Sometimes changing just one small thing makes a big difference. If anyone has made changes that helped turn a bad campaign around, it would be great to hear about it.
