You do not need an AdSense account to sign up for Ezoic- however, if a site is not approved by AdSense they will not get approved by Ezoic. This is just because we strictly follow and implement Google policy. If a site doesn’t have an Adsense account before signing up for Ezoic, our reps will ask them why they don’t have one, this is because we recommend linking AdSense to Ezoic because there are a lot of optimization benefits and makes the onboarding process quicker.
