Hey!
I mis-typed my link last time but Ill start with that and break down the links I have.
ABOUT.ME
about.me/besoyt
-This is a GREAT "proffile" for you to have all of your social media links in one place for people to check out. Instead of having to always link each and every one multiple times when you're promoting your links - you can just link one. Its really self explanatory - There are common social media links that you can just link to their icons and ones that are less common you can manually add the link. You can customize your font/wording and background as well. Theres a bit of a Google+ feel to it in the fact you can make lists and add others profiles to it and check them out.
INSTAGRAM
http://instagram.com/besoyt-I love instagram. I mostly use it for my youtube personality stuff and RL things but I have included my crafting before as well, which I will probably start to do more of. People love pictures! You can use hashtags to network your posts further, but I hardly do that - I probably should.
FACEBOOK
www.facebook.com/besowow
www.facebook.com/celestiala
-The only pieces of advice I have on Facebook would be to interact with your fans on the page. The more you respond and encourage conversation the better. Also, there are widgets to link your shop - have one of those so people can view from there as well! Anywhere they can see your work is a plus!
TWITTER
www.twitter.com/besoyt
-Again I mainly use this for my youtube personality/entertainment purposes but as I've started up my store to include geekery, I will be using it to promote as well.
-Be active and be interactive with your followers. Search out a subject related to your craft and interests and follow people and places you would want to know more about or can see yourself talking to. In turn, usually people will follow you back or see your interaction with these people and check you out.
TUMBLR
http://besoyt.tumblr.com/-I have one but never really got into it. so I don't really have tips.
YOUTUBE

www.youtube.com/besobeauty
-Theres way to much advice I could give on youtube to fit into a post. I have done crafting related videos and plan on doing more starting next month which will be great to get back into. Most important - be genuine and don't fret about people hating on what you do. Post content as frequent as you can and make sure to link it out!
GOOGLE+
https://plus.google.com/110093812695954952454/I don't use this other than to + my automatic video posts
WEEBLY
http://besoyt.weebly.com/I started a website/blog which has helped traffic to my sites quite a bit. I haven't included my Etsy just yet, but will add a page for that soon as well, now that I've reopened.
-With any website, make sure you update as frequently as you can and have your other links available for easy access.
OTHER
These are just a few other social media sites I have that don't really pertain to my Etsy (except DeviantArt)
-Raptr-
http://raptr.com/BesoWoW/aboutShowcases my gaming activity. I also link my YouTube videos here.
-TwitchTV-
http://www.twitch.tv/besowowThis is where I livestream my gameplay. I've crafted during a stream once but probably wont again as its not in their terms of service.
-DeviantArt-
http://besoyt.deviantart.com/I offer digital art commissions through my website here. I started doing this on Etsy as well, but have had more success outside of Etsy for projects.
Not sure if any of that helped, but if you have further questions about anything I use or may not have listed don't hesitate to send a convo my way :)
