グーグルアドセンスを使うと、アフィリエイト広告は？

Thanks for reaching out @thegoronyan25.

Unfortunately we’re limited to Site Kit queries here in the plugin support forums. The product experts over at the AdSense Help Center should be able to assist more than we can here. From what I suspect, affiliate ads should be fine as long as the ads used are in line with AdSense policy, see below

Hopefully the product experts will be able to confirm this for you. Best of luck!
