I'm just starting to setup my adword account for my new product but I'm a little bit lost as to how many keywords I should target to begin with.
I'm in the personal finance niche. Does anyone have a general rule of thumb to start out with? Maybe choosing 5 target keywords and then having like 15-30 keyword branches off each main? Then for the actual ads themselves, how many do you suggest?
Sorry to sound like a complete noob, but any advise would be appreciated
