This is something I am always on the look for, free ways to advertise my Etsy shop. If you are like me you probably have the same "advertising budget" as many of us Etsians do, $0. However, we are all business owners, and all business advertise in one way or another. Instead of throwing hundreds of dollars away my focus is doing it for little to nothing.
This first site is an easy way to get your shop seen and you can add yourself to it as often as you like, its called 100 craft links, and it's only for crafters with hand made items. It shows 100 shops at one time and as people add you slowly go down the list until you drop off. You are able to add a little blurb about your shop and people who are looking for handmade goodies visit this site daily!
Another great site is http://craftori.com/ used to be known as Etsylush.com but has now opened a new site. Here you register for FREE (they do have paid section but I don't use it), than post your etsy items. People do come here to shop and I have gotten several hits from it. Again this is a site you can ad to weekly when you need to promote your shop.
My favorite place to submit my items is http://www.etsycontest.com/
Here you submit your entire shop, and pick a day that you like from their calendar, and they will pick and item to put in the contest. Since submitting I have been in the contest at least once a month and actually came in 1st place last month!! Basically once they put your item in the contest people will go through and vote for the item they like best 2 at a time.
One more site I have been able to get some views from is http://www.linkreferral.com it is an easy sign up process and FREE. You add your shop and than you can visit other sites and rate other sites in order to post your ranking and get more views. Lot's of other Etsians are on their and it's an easy way to network with other shops.
Now my last site is FREE the first time you use it, but from there on you can pay for more credits or refer people. Its called EtsyonSale.com and its a great tool and promotional site. You can use it for many things but they way I use it to drum up business is to run a sale (4 credits, you will get 5 when you sign up) you can pick the amount % off you wish to give. You can pick entire shop or 1 section.
The site will change your images to reflect the sale and adjust prices (once sale is over they will to all the work to fix it back to the way it was. They also have a page on their site for people to shop to see who is having a sale on Etsy. Whenever I run one of these my views and sales shoot up. Much easier than a coupon code and worth the extra publicity.
Hopefully this will give you something to work on to get more views/sales for your shop at little no cost. I will collect more free sites and share them with you again soon.
