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. 
That site makes me mad some days.
