Awin vs ShareASale: Links, Tracking, and Reliability Compared
Awin is major affiliate network known for the broadest EU/US retail merchant coverage, especially post-ShareASale-merger; ShareASale is affiliate network (merging into awin) known for legacy mid-market retail programs — but it is merging into Awin, so treat it as transitional. They solve different problems, and many publishers use both at once for different merchants. Mechanically they differ in link anatomy and failure behavior — compared in detail below.

How Awin links fail
Merchant leaves Awin
The most damaging failure. The link redirects to Awin’s closedMerchant page or shows "this link is inactive". Clicks keep flowing, commissions stop. Awin does not rewrite or fix your old links when a program closes.
Destination page dies
The Awin hop works, the click is tracked, but the ued destination now 404s or redirects to the merchant’s homepage. You keep your cookie but conversions collapse because visitors land on the wrong page.
How ShareASale links fail
Merchant migrated to Awin
The defining failure of the ShareASale era’s end. Your old link may still reach the store, but attribution happens on Awin now — your ShareASale link no longer credits you. These links need to be regenerated on Awin.
Merchant closed their program
The link shows "merchant not found" or "program suspended". ShareASale historically hosted many small merchants, which churn more often than enterprise brands.
How to choose
- ▸Choose Awin for the broadest EU/US retail merchant coverage, especially post-ShareASale-merger.
- ▸Choose ShareASale for legacy mid-market retail programs — but it is merging into Awin, so treat it as transitional.
- ▸They are different kinds of platforms, so this is rarely an either/or: many publishers run both simultaneously for different merchants.
- ▸Whichever you use, the operational risk is identical: merchants leave, campaigns end, and product pages die — on both platforms — without notifying you. Monitoring matters more than network choice.
Frequently asked questions
Can I use Awin and ShareASale at the same time?
Yes — publishers routinely run multiple networks side by side, since each merchant picks its own network. The cost isn't platform conflict, it's audit surface: two networks means two sets of link mechanics to monitor.
Which pays higher commissions, Awin or ShareASale?
Commission rates are set per merchant program, not by the network — the same brand often pays identical rates wherever it runs. Compare specific programs, not platforms.
Do Awin and ShareASale links break differently?
Yes. Awin: merchant leaves awin is the most common failure. ShareASale: merchant migrated to awin. Afterlink validates both with network-specific error detection.
