Welcome to the Q&A Forum

Hi WebDesignBarrie, I'm not totally sure I know what you mean by "local rich snippets". I'm going to take a guess that you are talking about using Schema??? If so, yes, it is completely fine for a single business with multiple physical locations to publish a unique page for each location and put Schema markup for the location, as well as for other elements like testimonials, if desired. And, it's also fine to have more than one location in the footer. My rule of thumb is that it's fine to do this provided there are less than 10 locations. If there are more than that, I think it makes the footer too unwieldy. It sounds like you have just 4 locations and should be fine. If I've misunderstood your questions, please just let me know.

Thanks for coming back to this thread with more info. I am always eager to hear about local business decision making because there are numerous approaches. I sincerely hope this works out well for you. It's a big effort to branch out. I like this reason you've listed: " Additionally, we use the city name in anchor text in backlinking. " Sounds good to me. And that's good that you've got the local area code phone numbers. So important! Good luck, Web Design Barrie! Miriam
