Because Google and Froogle are featuring eBay stores in their indexes, SEO techniques should be considered:

– If you sell on eBay, submit your store but choose the store’s name carefully as it goes in your title tag.

– Having a few hundred items in your eBay store gives you a huge number of inbound links.

– Your store department names should be keywords.

– Build an “about me” page that has links to each major department of your website. Links from your “about me” page are allowed but you are not allowed to link out from your listings.
