Using price comparison sites and shopping sites can expose you to new customers who could buy your products. This can also boost traffic to your site too and get your site and brand more well known.

To use a shopping bot you will need to build a feed. Then your products will be listed and they will be displayed when a user searches on particular keywords or they navigate through the menus to the areas selling your products. All products available will be listed with prices. On some sites, the lower the price, the higher your listing will be. On other sites, your product’s listing position will depend on your merchant rating, which changes depending on how many products you have sold.
Some sites will charge a one off set up fee and then will charge per click through. Other sites are free but then will charge per click through. When a customer clicks on the product, they will be taken through to either your website or your merchant store. Be sure to optimise your products with keywords and ask your customers for reviews on your product and service. You don’t even have to have your own website for some sites, as the site will set-up an online store for you.
