Normally Google Issues Payments For Adsense Publishers after 24th Date of a month but it seems like this month December 2012 Google is going to issue payments much earlier to its publishers and that is because of Christmas season.
Its 19th December today and Adsense publishers from different parts of the world have already started reporting that they are seeing Payment in Progress PIP in their adsense accounts.
Several publishers from India, Morocco, Serbia and other countries reported that PIP has appeared in their accounts today on adsense forums.
PIP (Payment In Progress) appears 1 or 2 days before the PI (Payment Issued) in Adsense Accounts every month normally. Adsense Publishers seems very happy on this great surprise by Google 🙂
