How can I verify a channel's earnings before buying?

To verify a YouTube channel's earnings before buying, ask the seller to provide screenshots of their YouTube Studio Analytics dashboard showing revenue, views, and watch hours. You should also request screenshots from their Google AdSense account showing monthly payment history. Compare the channel's public view count with the reported income to ensure the numbers are consistent. If anything seems suspicious or the seller refuses to share analytics, it is a red flag and you should avoid the purchase.
