Been testing that and honestly its a pain. Smartlinks promise easy scale but half the time they send you to low converting offers or spammy redirects. Individual offers take more time to test but at least you know what youre sending traffic to and can optimize better. For beginners trying to find their footing I say start with individual offers, learn how the offers perform and then maybe layer in smartlinks if your data says its worth it. But jumping straight into smartlinks without understanding the flow is just setting yourself up for a flop.
