I'm trying to reach 300,000 impressions per day, which normally hasn't been a problem, but I have a not-so-great landing page (developers are working on it) and it seems that perhaps the US/Canada market targeting is off.
Do I need more keywords per ad group or perhaps more targeted ad groups?
What is a good number of keywords to have per keyword group? I've heard numbers as low as 20-40, but that seems too low.
Can you suggest any good keyword building tools for content network targeting?
I have to say I didn't really believe it but I tried it and had better results.
Try creating 3 different AdGroups, one for the direct product/service, one for a complimentary prod/service and a 3rd targeting the audience demographic.
Give it a try and see how well it works.
