What could I do if my AdSense ad serving has been limited?
I have faced this issue!
It happened because I clicked on my ad by mistake on my pc. But it was recovered within a month. So just have some wait & don’t put any invalid traffic. If possible change the theme to simple & keep adding new articles. It will be working soon. The last option if it doesn’t work, then simply remove your site from AdSense & Re-Apply. It will be accepted faster than the first time.
