Look at the reviews. For example, I am the owner of an RV Campground and looking to fill RV Spots for the summer. I would look up RV Dealers on Facebook and checked out the reviews. "My family and I just bought a new camper we love it!... Tom Smith" I would go to Toms' profile and lets him know about the park. This approach can work for any niche. WICKED SMART!!!Another way is to look up recommendations on Facebook! "Can anyone recommend the right camping spot for the summer?"
Take advantage of Facebook Messenger, Talk to people get to know people!

I believe that small business owner make any community great and they should get the same services that the big corporations companies get for a reasonable price and get to learn how to marketing themselves.
