I have several accounts with adwords that I manage for clients. This week I started another new account and have had nothing but problems and a very low standard in customer service!
I am not new at this so I know what I am doing. In fact the new account is a direct copy of another account I manage, with only a few minor changes. However, I have had nothing but problems and the new account keeps getting slowed for no reason, also charges are made against it.
Also, since the latest changes, the CTR on all accounts have increased with NIL return. I guess this may do with the new search feature that publishers are able to put on their sites, along with the 'new improved' keyword match. I have talked with some of my clients about their ROI and some have reported a 50% decrease, with some reporting a 100% decrease.
I have used adwords for some time now and it has had its ups and downs, but I feel this may be the end of the road for me as my clients are wanting better results. The icing on the cake came in the last few days as I watched adsense on all 36 channels drop by 50% on a large number of my own content sites.
