I never would have come across this useful tidbit, but I started selling stuff on Ebay and I stumbled into Google Store Connector while looking for ways to get more traffic to my Ebay store. Basically what Google Store Connector does is link up with your Ebay store and download all your products into Google Base. Now maybe you have never heard of Google Base, but it actually a great way to get your products noticed and of course like most things Google (including Google Store Connector) it is 100% free!
Think of it this way, if someone is searching for a product they are not necessarily going to go to Ebay, they will go right to Google. So lets say you are trying to sell Hummel Figurines, if someone types in "Hummel Figurines" and then hits "Shopping" on the top of Google's search page they are indexing things that are in Google Base. You need to be here!!
So basically what you do is download the program Google Store Connector, which is free and then enter in your login info for ebay so it knows where to pull your items from. After that you are just 2 clicks aways from having your entire store posted on Google Base and in turn Google Product Search/Shopping! Just hit Copy Items From My Store and then Publish To Google Base and you are done!
One important factor to note though is that you need to have a "Buy It Now" price and a set (not calculated) shipping price or Google Store Connector will not publish your item. Just make sure to post your items to Google Store Connector soon after you put them on Ebay and you will avoid any problems. Run Google Store Connector again after your items have sold and it will automatically delete the items that are out of your store and add in the new ones!
Now Google Store Connector doesn't just work with Ebay, it also works with Yahoo and osCommerce as well. This is truly one of the best ways to get more traffic and in turn more bids to your Ebay store so go ahead and try it out, just don't forget who told you about it when your sales start piling up : )
