The so-called absolute address is with the domain name directly written to the connection address such as: http://www.php1.cn/jueduidizhi/ and vice versa is relative address, connection and hyperlink plus the knowledge of the path/jueduidizhi/without the domain name.
We recommend that you use absolute addresses on the homepage:
First, after the new site is set up, using the absolute address can avoid a lot of troubles in the future, such as people mirror your site.
Second: the domain name has an extra scattered weight. it is best to directly use the absolute address, or use the 301 targeting.
Third: when different domain names are resolved to an address, it is easy for the search engine to misunderstand, do not know which is the main battle.
Fourth: search engines only include Level 2 or level 3 domain names provided by virtual hosts, but not the primary domain names
