E-Commerce websites have an advantage over other website types in that they are highly SEO friendly due to the high volume of category and product pages. All of these pages have the potential to rank in the search engines. Products tend to be grouped into category pages eg a printer website will have a category for office printers which can be set up to rank for keywords like "office printers" "office printing solutions" and so on. In addition, every product on a website has its own product page. These pages can also rank organically in the search engines. Online retail websites that are well optimized (for SEO) can therefore achieve high amounts of targeted traffic to their main pages. Due to the fact that there is no incremental cost per click associated with organic traffic, it is one of the most attractive channels for an online retailer. As a result, it is an important task to focus on.
