I have pages for both our farm and for my photography biz. Word of mouth has been a better investment than promotions via FB. I used to do promoted listing on etsy for another hobby (building steampunk lamps), and it wasn't worth the money in any way whatsoever. You need to have a real advertising budget in order to take advantage of the impression generation engines on most promoted site tools, because the site managers preference promotions based on money spent. I dno't begrudge them that at all, it's how the world works. However, I'm not made of money and I'll do my own slow organic growth instead. Working so far.
