Hello, I recently joined Yahoo search marketing, as I am an advertiser on Google more than a year now. I must say Yahoo's control panel is less advanced than Google's. For example when I exclude a keyword in the administration level to be effective for all adgroups, it does not really work. Let me give an example: I have a keyword of 'floor tiles'. I want to exclude 'ceramic' in any combination of this phrase. I entered 'ceramic' and 'ceramic floor tiles' as exclusions, however when I type 'ceramic floor tiles' on Yahoo search, I still see my ad! Other questions: Is there a way to test the ads without effecting CTR as adpreview on Google? Why the data for the campaigns is not updated regularly throughout the day? I will ask when have more questions. Thank you.
