I think you need to add the UTM parameters after your website URL. UTM parameters help you identify which sources are coming from.
For example, your website is mystore.com. You want to track users from abc. You need to follow these steps:
- Step 1: Add UTM params to your link: MyStore
You can use this website for free to add UTM params. The params value is defined by your preference. - Step 2: Send that link to your partner. Ask them to post that link on their website.
