Conversion tracking records actions like purchases, sign ups, or downloads after someone clicks an ad. Sometimes the system counts the same action more than once, which creates duplicate numbers. This can happen if tracking codes are installed more than one time on the same page. It may also occur when two tracking tools measure the same action separately. For example, both a website script and an ad platform may record the same purchase. Checking where tracking codes are placed usually solves the problem. Could website updates sometimes create these duplicate signals?
