@roguegirlvintage: I'd suggest using the same SEO techniques you've learned for your Etsy shop on YouTube. Some of my things got lots of views simply because mine was the only video of the topic, as I had no clue about SEO when I made them.
I embedded them into my eBay listings, but Etsy does not allow that, and anyway, when the listing has ended, it no longer helps. Etsy DOES allow you to post a link, link in this listing:
http://www.etsy.com/listing/76651890/yamaha-trumpet-ytr2320?ga_search_query=trumpet&ga_search_type=u...You can post videos on your Facebook pages, both personal and business.
I'd try to offer a video no one else is offering. The success some of my videos have achieved really surprises me. I'm really no expert on this at all, but hadn't seen anyone else suggest this on ES forum yet, so thought I'd throw it out there. Maybe there are others who know more about this who will chime in.
Now, I wish I knew how to make a GOOD quality video. Many of the ones I've made are so bad, they're really kind of embarrassing.
