I set up ad groups originally with exact match but for a lot of areas it says low search volume. But doing a keyword diagnosis sometimes reveals that they are being displayed even though it looked like they were not going to be.
I set up broad match modified on some ad groups to see what difference this would make in terms of increasing volume (i set up negative keywords too) but this, for some, still says low search volume or then later on changes to showing. So i presume that you have to leave keywords for a few days to get a feel for whether what adwords is telling you originally is right?
But my main question is should you use exact match and broad match modified within the same ad group? Does this help with regards to cpc?
Or is it just simply better to go for broad match modified and ensure that your negative keywords are well equipped?
