6) Practical combinations for using eBay and a Prostore.

* Use the eBay auction listings to attract traffic to your ProStores website through the checkout redirect.

* Make sure you mention your ProStores site in your About Me page (the only place on eBay you can directly link to an external website) and make sure your customers know you sell just as wonderful merchandise there.

* eBay launched Reviews and Guides, enabling the Community to write reviews and guides of products they buy and sell on eBay. We encourage you to start writing reviews and guides right away and receive the following benefits

    -Link to Your Listings and About Me pages: Reviews link to your user ID, which link to your listings and About Me pages. Guides can link to your eBay store, About Me page and listings. Directions on how to do this can be found on the Reviews and Guides page.

     -Natural Search Benefits: Reviews and Guides show up in Natural Search. This means that buyers shopping in search engines like Google are more likely to find what you’re selling on eBay if you write reviews and guides.

7)  PayPal Shops:

PayPal Shops is a directory of online businesses and organizations that accept PayPal payments.

When you enroll in PayPal Shops, your online store will be included in our directory of websites that accept PayPal. At this time, there are no fees to register or maintain your enrollment. PayPal Shops allows millions of PayPal members instant access to your website. PayPal members can easily search for your product or service through our PayPal Shops directory and can be confident that they are purchasing from a reputable seller. Once buyers send you a PayPal payment, they will be invited to visit your website. This provides customers with a direct link to your online store, encouraging them to view additional products and services.
 

Register for Shops free! Online sellers who accept PayPal can register for PayPal Shops, at no cost, or learn more about PayPal Shops in the Shops Resource Center.  

I can't put outside links to other sites in this review. However you can go to Paypal and do a search help on their site and find the above information.
