I have been using AdWords for one year. It was going smoothly and we were receiving good result from AdWords.
Two months ago we rearranged the AdWords for better optimization by pausing the campaign which we had been using for a long time and created two more campaigns that arranged the keywords hoping for better results. We didn't change anything other than separating the campaigns. Since then we have not been receiving no inquiries for our firm from the ads. Even after waiting for two months, there has been no improvement.
Are there known problems with pausing a working campaign and splitting it into two new campaigns?
