Conversion tracking is how you know if your ads are truly working. A conversion means someone takes the action you want, like buying a product, signing up, or filling a form. When you set up tracking, you place a small code on your website that records these actions. This helps you see which ad brought real results instead of just clicks. Without it, you are guessing. With it, you can focus your money on ads that bring sales and pause the ones that waste budget. Does this seem like something many beginners ignore?
