Dani's last thread (in the advertising sales / affiliate section) triggered something in my brain. Using PPC to promote ebay auction listings!!!
What do you get when you combine Google, Yahoo, and eBay together? A MASSIVE reach when it comes to promoting your goods or services on eBay. I have experienced excellent results by making Adwords and Overture advertisements link to my eBay auctions. But when doing so, be clear with your ad copy. Almost every search engine PPC ad I see that links to eBay are eBay affiliates. Therefore you must be creative with your copy to distinguish yourself. A good example is as below:
Red Puma Running Shoes
New in box. Male Sz 10.
Auction ends March 3.
ebay.com/mylisting
This will avoid confusion, and instantly tells the searcher that you are advertising a unique item on eBay.
Add PPC ads to your listings and you'll create a larger pool of potential bidders. It's as simple as that.
