URL Normalization in SEO is a more important link, at the same time there are different versions of the Web site, not only may cause replication, but also can not correct the concentration of weight.





currently most Web sites, binding domain names are with the WWW and without two versions, and even many sites at the same time binding multiple domain names. After processing (jump, CNAME ...) may not have any impact on the visitor, see the same content, but for the search engine, it is not possible to determine which URL is the real home page.





controllable factors, site content links should be maintained in the same version, such as the whole station, return the address of the first page is a fixed version. But there is also an uncontrollable factor, is that others link to your site, the use of the Web site. A lot of spontaneous links or exchange links, others may omit the WWW, or use the binding of another domain name.





external factors are not controllable, we can control from the inside of the website. Using Apache. htaccess, use 301 redirects to standardize URLs.





Create a new empty file, file name. htaccess, fill in the redirection rules, and upload to the site root directory.
