About this tool
UTM tags are short labels added to the end of a link, like ?utm_source=instagram. They don’t change where the link goes. They tell Google Analytics, and most other analytics tools, where each visit came from, so you can see whether your bio, your newsletter or a QR code sent the people who bought.
Use the same words every time: always “instagram”, never “Instagram” one week and “IG” the next, or your reports split one place into three. Source, medium and campaign are the three that matter. On OneLink Pro, your page can add these tags to its links for you, naming the app each visitor came from.
