One sign is if your ads get clicks but very few people actually buy or take action. Another is when engagement is low, like few likes, comments, or shares. You might also see high costs without results. This often happens when the audience is not interested in what you offer or the message does not match their needs. Looking at the data about age, location, or interests can show if you are reaching the wrong people. Testing different audiences in small steps can save money and give better results.
