Google AdSense made a checklist to help new publishers setup AdSense account and start earning money. Visit the AdSense Checklist on AdSense U.S. Help Center.
The checklist has a total of 20 items, divided into 5 parts. Each item has a short description/tips and a link for more information. When you check an item, there’s a progress bar update accordingly.
This is helpful for beginners to Google AdSense. Existing AdSense publishers are also recommended to check if you have done all the items in the AdSense checklist.
If you ask… Yes, I got 100% at 1st check.
