I had a few keywords up on google adwords with a quality score of 7. I had a ctr of 10% and everything was going fine. The next day I start seeing thousands and thousands of impressions yet low amounts of clicks and my keywords lose their quality score and the bid rises. I deleted those keywords and found some other ones using the Google Adword tool to find keywords with very low competition. As soon as I add the keywords, the bid rises to 40c. What am I doing wrong?
