I notice with Yahoo Search marketing you get a quality index for each of your ads. But does that quality index correspond to all of the keywords in your ad group? if so, would the best optimization be to have one ad group with one keyword so you can see the quality index for that one keyword rather than the quality index of the average of all the keywords in that ad group?
Hi Sandyjo, Yes and no If your keywords in your group are all relevant to a certain subject/theme then you really don't need to break up the keywords like you stated. However if you want to test a particular keyword on its own it does not hurt to do so. I would take the converting Keyword on its own and place in a ad group to see how it converts on its own and how your ctr/quality index is effected. Cheers, zigzagzigalar
