thank you for this great article about match types. It was really a pleasure to read it.
But I wonder about one thing: You mention to put every match-type to a single adgroup, so you can analyze adgroups and figure out different performances etc.

But how do you structure your whole account then? Do you put all keywords with the same match-type and the same subject to one adgroup or do you put every keyword with its match-type to one adgroup – so you would get a bunch of adgroups in the end?

To be more exact: I'm managing accounts with around 70.000 keywords (yes, already same keyword with different match-types) and I'm thinking about re-structuring it. So my question is, what would be the perfect account structure in the end?

Thanks in advance for your feedback and keep up the good work!

Best,
Thomas
