In terms of content, be sure to include features like side-by-side product comparison guides and customer reviews and ratings. If possible, list product availability--as even if something is out of
stock, it's better for customers to know up front than when they get to the checkout screen.
Meanwhile, don't be afraid to up- and cross-sell your customers during their research and purchase process. "Provide a list of related products that typically go along with any current items in a shopping cart or product being viewed," deGeyter says. "If applicable, allow shoppers to purchase additional services such as product engraving, customization, gift wrapping, etc. These features can make a nice up-sell opportunity while giving the visitors that customization offer that they need for special purchases."
