Hello,
Within 28 days will be made 9 steps work:
1 - Initial Settings.
2 - AdSense validation attempt on day 5 (as Google generally takes two days to respond, or respond to the 7th day).
3 - Adjustments suggested by Google.
4 - Adsense validation attempt on the 12th day (usually because Google takes two days to respond, or respond by the 14th day).
5 - Adjustments suggested by Google.
6 - Adsense validation attempt on the 19th day (usually because Google takes two days to respond, or respond to day 21).
7 - Settings suggested by Google.
8 - Adsense validation attempt on the 26th day (usually because Google takes two days to respond, or respond to the 28th day).
9 - approved Adsense account improvements or report in the coming months.
Regards,
Marcelo Furtado
