Split Testing Keyword Lists – Zip Codes vs. Cities

One of the questions I received a lot in my former career as CTO of Angular Marketing was whether to use cities or zip-codes in site architecture. For example, imagine a client comes to me who runs tennis clinics across the North Carolina triangle (Raleigh, Durham, Chapel Hill). Should they build their website like this…

or like this…

Well, it turns out there is a really easy way to answer this question by split-testing with Moz Keyword Explorer lists.
