When you are approved for Skimlinks you are automatically approved for 99% of the Merchant programs we work with. There is no need to apply to individual programs.
You can confirm if your domain is approved for a particular Merchant by finding the merchant in your Publisher Hub Merchant search. If the merchant appears, then you can use Skimlinks to earn commission from their program!
Please note that this is set at your domain/site level so if you have multiple domains/sites in your account, then you need to search with the relevant domain selected in the top left corner and you may see that some merchants are available on one domain but not others.
You can also download our Skimlinks Editor Toolbar and when you visit a Merchant site, the toolbar will drop down and let you know what commission rate that Merchant will pay you, or if it's a Merchant that will not pay.
