Linda B - all your Etsy activity is optional to put on your fb page. Successfully linking your etsy shop to your fb business page for your etsy shop will get you the like button at the top of your etsy shop. This simply enables people to easily click the like button straight from your shop. Seems like a good idea to me, I used this link, you will find it very informative:
I have had our up and going for a few weeks now - gotton 27 likes that have shown up (though our fb activity shows more people have clicked the like button then that). Trying to reach 30 likes so I can customize our URL address.
I'm good on computers and usually can figure this stuff out, BUT I am fairly new to fb and still am not sure why only some of the likes are showing up...
Linda, I hope I helped you here, if you have any other questions feel free to ask! :)
