Everything about sub IDs

What is a sub ID?

A sub ID is an extra tag you add to your affiliate link to measure your own channels. Your base link stays the same: the SaaS company's address plus ?red= and your personal slug, for example example.com/?red=yourname. The sub ID is added to it and tells you which of your channels the click came from.

What you can separate with a sub ID

• Channels: your blog versus your newsletter versus LinkedIn
• Placements: the same program in several blog posts, or on several sites
• Campaigns: a one-off launch email versus your regular newsletter
• Ads: one sub ID per ad campaign, if the program allows paid ads

Example: the same link on several blogs

Say you placed your affiliate link for the same SaaS company on several blogs. Give each blog its own sub ID. When a reader clicks the link on one of them, the sub ID travels with the click, so you can see which blog performs and put your effort where it pays off.

How to use sub IDs

1. Open Links in the left menu of your dashboard. Your links for every program you joined are there, and the page shows the structure for adding a sub ID.
2. Add a sub ID to your link in that structure, one per channel or placement, and use each version only in its own place. You can add as many as you want.
3. Open your Reports page and go to the by sub ID section. It shows clicks, referrals and commissions per sub ID, as soon as a link with a sub ID gets traffic. Then move your time to what earns money.

Because the structure is always the same, you can also add sub IDs programmatically, without going through the app.

Tips

• Use short names you'll recognize later, one per channel or placement.
• Keep the same naming pattern across programs, so you can compare channels.
• Don't change your slug to separate channels. After a slug change only the new link works, and clicks on old links are no longer credited. Sub IDs are the way to split your channels.
