I have an Adwords campaign and it's cost is almost a third of my sales price. I've tried everything, ad versions, dynamic keyword insertion but costs and CPC are still skyrocketing as I am currently ranking between 1 and 4 in most of my keywords. I haven't created any landing pages for this campaign yet, and I am not sure but I might be using too many keywords. Another issue is that a big part of my business comes through phone calls. I am having customer service trying to get as many keywords as they can....
Any suggestions ?
