No, if you already have an affiliate account you do not need to reapply. You just need to add a secondary website to your account.
Secondary websites must comply with AvantLink's selection criteria and will have to be approved by our compliance team.
Note:
AvantLink requires ownership authentication for all web properties used for promotions. Affiliates are not permitted to use any sources or web properties not approved by the network. All sources of promotions must first be submitted as secondary web properties through the affiliate account interface, reviewed by our compliance team, authenticated, approved and listed as active (not hidden) prior to any affiliate links being used.
