I have an adwords account that is now approximately 9 months old and is performing reasonably well. I am able to buy a decent amount of traffic at an acceptable price that is financially viable for my site and on the whole my Quality Scores are not too bad. However today I loaded two new campaigns for new products and the account gave the keywords Quality Scores of 1 & 2 when the structure of the campaigns remains on the whole in the same format as my older campaigns. I am baffled by this, is there any advice anyone can offer to help me at all please?
