domain name with WWW, or WWW, is actually not so important. At least not because that was not because of the domain name with WWW visitors left out. The key question is whether a website adhere to the rules of url. Early in the website construction, is very important to make this decision, decided to take the WWW, it will not take up to 301 directional band WWW, and vice versa. Decisions after, the entire site must according to the rules of URL to deploy within the chain and the chain extension. Even after doing 301 redirect, if the station with chaos and link without WWW, outside the station also indiscriminately released outside the chain with and without WWW, it will cause the weight of the dispersion, search engines were included with WWW and without WWW page, website ranking will cause delay do not go on.
