You need to have as many links back to your shop as possible on the internet. Then you’ll come further up in a google search.
How you do this is promoting in lots of different social media sites don’t just use one social media site.
It also takes time to build up those ‘back links’ for instance it’s taken me two years to slowly climb up in a google search but it’s now working for me I’ve had more sales in the last 6months than in the entire time I’ve been on folksy.
Your photo’s, descriptions and tags look great from the one listing I checked.
It really is hard work and takes a lot of time to get noticed.
What social media are you using? and how often do you any promoting?
I tend to spread mine out so one day I’ll do something on googl+ another day I’ll do facebook and yet another day I’ll do twitter.
Also if you belong to any crafting forums and post often I would suggest asking permission to have a link back to your shop in your posts. Many crafting forums will allow this if you follow their rules.
I’m on 5 different craft forums and everytime I post on one of them my shop link is there and it gets picked up by google.
Here are some social media sites you can use.
Hope this helps
