I know a question coming from you is not going to be a stupid one. First time splitting it this way, so I will be taking one step at a time. If it doesn't work, reverting to my usual method is quite simple. Having said that, I would run it more or less the same. Create 2 or 3 campaigns, different priorities, use negative keywords to sculpt traffic etc. Just the fact that I will get to see the exact product triggered by search term, seems like really valuable insight to have.
