If you work with sub-affiliate partners, it’s important to set up your tracking links to better understand where your traffic is coming from. This helps you ensure your sub-affiliates are properly credited for the conversions they drive.
If you rely on a sub-affiliate network to promote your Seller tracking links, you’ll need to use impact.com’s SharedId parameter. Adding this parameter to the end of each link ensures that every conversion driven by your sub-affiliates appears in your impact.com reporting with the corresponding SharedId — giving you full visibility into the partners and platforms that influenced each Amazon purchase.
In Seller partnerships, avoid using SubId parameters in your tracking links. Doing so may prevent you from getting credit for conversions. Only the SharedId parameter is supported.
For detailed steps on generating Seller tracking links in-app or via API, refer to Create Tracking Links for Seller Programs.
The following tracking link methods automatically add a SharedId when you populate the relevant field:
To add a SharedId manually via one of the other methods, attach this string to the end of your link before sharing it with sub-affiliates: ?SharedId=<SharedIdValue>
Once your sub-affiliates start driving conversions for your Seller partnerships, you can view the data to see which sub-affiliate is responsible for each conversion. Amazon requires each link with a SharedId to receive at least 10 clicks before the data appears in your impact.com reporting.
From the top navigation bar, select Reports → All Reports.
From the Category filter next to the search bar, select Performance.
Select Seller - Performance by Program.
Below the report heading, set the Aggregate Level filter to
aa_creative_idinstead of the defaultaa_adgroup_id.This will display the
SharedIdvalues in the Creative ID column.For a full breakdown of the report, see the help article Seller - Performance by Program for Partners.
