Samallcompany thank you for your reply. I think you mean to chose mobile diveces in each campaign settings I already did that and I tried to chose only mobile diveces and then mobile with computers nothing changed. We used to show up in the first 2 positions in cell phones with the same settings. But we have a huge competition and we had fraud clicks attacks after that QS dropped to 1 for the most important keywords. Our ads showing only in computers . We tried to bid high and ridiculously high and we are not even in the bottom of the pages in cell phones.
