Ive noticed my ads on niches such as "Man boobs" or Premature ejaculation" are not getting any impressions. Yet the QS is "great" and my ad is on "active". However when i search for Man Boobs keywords on Google, i see ads about "man boobs" products. Why isn't my ad displaying on supposedly adult keyword searches?
