It depends on the type of listing, for example you are permitted to list contact details on a classified, you can see my listing here as an example Link hidden: Login to view
If you can do classified advertising, you can even have hot links built into the listing so customers can click through to your website from the listing. So if classified listing is an option for you, I would highly recommend considering it as a great marketing tool, we get the vast majority of our website traffic from eBay through our classifieds.
Now that is only for classifieds and that option is only available on limited categories. So if you are selling in a category that doesn't permit classified listings, a little trick is what is called crumbing, well at least that's what I call it lol. It's all about leaving hints without stepping over the line, a trail of bread crumbs for others to follow. A good way is to link an email account to your website, so if you had a site called Link hidden: Login to view
, you would link an email to that, for example Link hidden: Login to view
What you then do is use that email address for your eBay account, you will usually always get away with then also listing it in your item's description. For example, thanks for visiting our store or listing, contact us on Link hidden: Login to view
for further information. Some times you might get pulled up for that, some say they have, I certainly never have and have used the technique for years on non-classified listings.
What you can then do is bait the listing, so you say something like, plenty of other great bargains in store, what that does is flash a light to anyone who knows anything about the Internet, because when they go looking for the other great bargains and can't find any, then they will usually put 2 and 2 together and follow the bread crumbs to gregssstuff.com through your email address.
It's not a 100% effective way to drive traffic from your listing, but it's all about those little 1% things that all add up over time.
