I’m wondering if there’s a way to edit the affiliate link so that it goes to specific product pages. There are people that want affiliate links for specific products we sell, and when someone clicks on the image of our product, I want it to bring them to the product page, not the homepage of our site.
Thanks!
Yes you can do that, have a look at Affiliate Links – you can use the url attribute to link to any page on your site. The same holds for banners, see Affiliate Banners.
