Short version. A link can tell you it was opened, from which app, from which city, on which device, and what the person did on your own page afterwards.
What influencer attribution can and cannot see
A link can tell you it was opened, from which app, from which city, on which device, and what the person did on your own page afterwards. It cannot see inside Instagram or YouTube, and it cannot see an order placed on a marketplace unless the marketplace reports it. Shopmycode counts everything a link can see and says plainly what it cannot, so the numbers you share with a creator are the numbers you can stand behind.
Links, codes, or both
Links attribute the person who tapped. Codes attribute the person who typed, which covers the follower who screenshots a story and shops later. Give each creator both; the platform shows them on one line and pays either way.
Reading a campaign like a growth team
Opens without results point at the landing page, not the creator. Results from one city point at a market. A creator whose link is opened mostly from WhatsApp has an audience that forwards. Results per placement, over a few campaigns, become the rate card you negotiate the next fee with.
