In the world of eCommerce, search engine optimization is particularly important because eCommerce sites depend on user-generated traffic. Also, most eCommerce sites have a higher number of pages when compared to their brick-and-mortar counterparts.  These pages, varying in length and content, must be optimized for search. The eCommerce SEO route is different from that of the ordinary commercial or informational site. Typically, eCommerce sites have many pages that are highly optimized for search and are monetized with AdSense ads.
