When ads stop getting clicks or sales, it often means something changed in the audience, budget, or ad content. First, check if your target audience settings were altered or if your ad has been running too long. People might have seen it too many times. Refreshing your visuals or text can make a big difference. Next, look at your budget and bid settings to make sure they're not too low. Sometimes platforms like Facebook or Google shift competition, making it harder for your ads to show. It's also helpful to review your landing page to see if it's still matching the ad message. Testing new versions helps find what works again. Have your ads ever lost clicks after doing well for a while?
