Welcome to the Q&A Forum

The assumption it appears some are making is that a search for Spas in Key West only returns pages with Spas in Key West as the "optimized term" which is not true. If your traffic for the query is such that Spas "in" (each specific location) is higher, use in. Typically, that is not the query. Typically the way searches search in the broader sense is to alleviate that connector. If your research shows more for utilizing "in" , I would use it. Hope that clarifies. Good luck.

Thanks. I appreciate you taking the time to answer.
