However, if you choose to do this you have to be mindful of site etiquette. Page owners won't like it if you just use their pages to promote your own -- particularly if you don't introduce yourself or interact in any other way.
That's why you shouldn't just like their page so you can add your own links to their wall. It's always best to like a few updates, and say hello. It's even better if you can be complimentary (and sincere, of course). You could say something about the page -- or maybe the business itself.
If you do this for a while you can usually find a way to be subtly self-promotional down the track. And even if you don't the interaction is still worthwhile. Every time you contribute something to their page your handle is being seen by locals, remember. If the page is a particularly popular one, the numbers can add up to be substantial.
So, when beginning your interaction with a Facebook page, if you can say something that confirms you have been a patron, they will really appreciate it. If you do this at the start and keep returning from time to time to offer genuine comments, occasionally sharing their updates to your own page, they are much more likely to reciprocate -- thereby lifting your page's profile substantially.
With this in mind, here's a good way to get some local momentum happening for your Facebook page: Instead of beginning online searching Facebook, think of all the local businesses you already know and like, then look to see if they have pages there. Odds are they already do. And if they are in the hospitality industry -- one that has taken to social media with a vengeance -- it would be very odd if they didn't! Do this and getting the conversation started will be a breeze. You're sure to see some reciprocal activity happening much quicker than if you approached the pages as a complete stranger.
