My website targets users from a majority of different countries around the world. I'm having a hard time seeing how much of a budget I should put towards each country I'm targeting in Adwords. I would like to be able to just target all countries but I know that I would need a massive budget to pull this off.
How does your budget effect your targeting options in Adwords?
How detailed do your campaigns get in regards to targeting options with different budgets you set up?
