It's not necessarily bad for SEO, and in fact could be useful to the user. What you need to do is make sure you're marking them all up in schema.org markup to make sure the bots can understand the information a little easier. The best scenario is to create a landing page for each location - that way you can have a better shot at ranking for each market. Write unique copy, add a map (embed a Google Map), make sure you have complete contact information (name, address, phone, hours of operation, etc), and list unique products/services for each location.

Hi John! I'm afraid there isn't a way to "merge" campaigns together. Your campaigns are each tracking specific sub-folders and different competitors. You could use the New Orleans campaign as the primary since this is tracking all pages for the domain, then choose the top 3 competitors you want to track and add keywords (if there is room) from the other campaigns to track. Hope this helps
