The mistakes I made have been posted except the ones about the ad's description. The ad description has only 70 characters long and too short to write an ad to cover all the KWs. These cause the ad disable due to a short cut, the KW disable or low position due to low CTR, or high CTR but no conversion. Solution: small ad groups with better target.
