E-Commerce Design - Back to Basics

While developing e-commerce solutions remember few things. Can customers find the website? This is a critical factor in ensuring the success of a site. Can customers find through publicising the domain name and through directories and other publicly available sources of referrals? For the success the e-commerce site needs to be both search engine optimized (so products are optimised for key phrases) and search engine friendly (some search engines can't read query strings). What use is a store, when how great it may be, but the opening is hard to find, except for the select few.
