I created a small $2 a day campaign for a client that offers a very obscure service that is hard to generate impressions for. I ran the campaign for a week with a .05% CTR.
Then I create a ad words account for the client using the same ad and the same keywords and they of course want a $25 a day budget because they want to get a lot of traffic.
Then Goggle keeps slowing the entire account (screwing up a bunch of other campaigns that are doing just fine) because this campaign has no clicks on only 400 impressions.
Seems to me the problem is the $25 a day budget. It seems if I went back to the $2.00 a day budget Goggle wouldn't get so nervous so fast.
What do you think?
Is the 'obscure campaign' using what could almost be sectorally main stream keywords?
Perhaps your kw's need to be 'obscurer'; more targeted...
I went through a similar situation some months ago - where I though the kw's were industry specific - but performance showed otherwise.
Changing my approach I went from an average ctr of 0.30 - 1.0%, to 0.4 - 25%+ with several kw's showing in the Premier slot! It wasn't the budget, or cpc that I changed...
I would recommend that you actually search G (and other engines) using each key word/phrase and see what comes up in the first few pages - this will determine whether you are using the kw/phrase relevantly or not...
I also think that you will find two/three "word kw" [strings more useful]...
Good luck
