How to change adsense on a purchased youtube channel
Answer:
In Studio, open the Earn tab and find 'YouTube Partner Program options.' Click Change, verify your identity, then sign into the new AdSense account and click Accept Association to complete the link. YouTube allows this switch once every 32 days. If the channel is already monetized, there's no need to reapply for the Partner Program itself — just make sure the new AdSense account is fully verified and your tax information is in order before initiating the change.
