Time limit for AdSense referrals earnings is now 180 days
You may have noticed today that the time limit for AdSense referrals is now 180 days. Based on the feedback we heard, we agreed that 90 days may not provide enough time for your referred publishers to complete earning $100. Therefore, we decided to double the window. This change is retroactive, so it will also apply to AdSense signups that occurred more than 90 days but less than 180 days ago.
