A quick question... I have one adwords campaign that has a poor quality score all around yet is still getting me conversions so I don't want to halt it. Does anyone know that if by keeping this campaign active it will have a negative impact on my other campaigns? Thanks
Your objective is to improve its quality. If it's making a profit, you shouldn't immediately consider deleting it. Keep split-testing ads, putting poorly-performing keywords into custom ad groups, etc., and you should achieve your goal.
