Sub-IDs let you track which traffic source generated each click and conversion — without creating extra links. This is a standard feature in professional tracking platforms.
How It Works
Just append any identifier after your slug in the URL. No setup needed — it works instantly with every link you create:
your-slug/facebook your-slug/google-ad1 your-slug/email-march your-slug/youtube-review your-slug/solo-ad-john
Everything after the slug becomes the sub-ID. The visitor is redirected to the same destination — but the sub-ID is stored with the click.
Alternative: Query Parameter
You can also pass the sub-ID as a query parameter if you prefer:
your-slug?sid=facebook your-slug?sub_id=google-ad1 your-slug?subid=email-march
All three query param names (sid, sub_id, subid) are supported.

Where Sub-IDs Appear
Dashboard — Sub ID column in Recent Clicks and Recent Conversions tables
Link Stats — Full Sub-ID Breakdown table with clicks, conversions, revenue, conversion rate, and EPC per sub-ID

✅ Example: You're promoting an offer on Facebook and via email. Create one link (/my-offer), then share my-offer/facebook in ads and my-offer/email in emails. Check the Link Stats page to see which source drives more sales.
💡 Tips:
Sub-IDs are case-sensitive: /Facebook and /facebook are tracked separately
Keep sub-IDs short and descriptive — they appear in tables and exports
No limit on how many sub-IDs you can use per link
Clicks without a sub-ID show as empty in the breakdown — that's normal
