Is it best to section out your PPC campagins into exact, phrase, and broad match?

Hey everyone, I’m about to start my first PPC run and I’m a little confused as to what would be best for someone just launching their product, especially when it comes to exact, phrase, and broad.

I’ve seen people separate their campaigns into these three categories like they would have 30 main keywords in a list, and then create three separate campaigns for exact, phrase, and broad, and I’m assuming they would just copy and paste each 30 keywords into these three separate campaigns so effectively the only difference would be the matching type.

Is this a valid strategy? Also when you separate these I assume that you would have to separate the budget, so instead of having a 12$ budget for your main keywords, you would have a 4$ budget for each matching type of your main keywords.

Is this something that you guys would recommend for someone just launching their product? Or maybe I missed something, either way, please let me know, any help is greatly appreciated.
