Did you know once the customer clicks on your eBay link that eBay tracks the buyer longer than just the first click? They use what’s called a ‘cookie’ to follow the computer as it moves around the Internet. By tracking the customer eBay can credit you with affiliate revenue even if they don’t purchase as soon as they click.
EBay tracks that buyer for 30 days – so anytime within the next month that the computer returns to eBay you’ll get credit for the next purchase (only one). However, eBay gives credit to the last link that was clicked affiliate link. Which means if the buyer clicks on someone else’s affiliate link after yours they’ll get the revenue.
