Is the above code, we copy, the URL is changed, this code is the use of Baidu, because the SEO tutorial network is also a mobile version, but I found that when the mobile phone access is still appearing on the computer version, so I was thinking how to automatically appear mobile phone version of it? I think for a few days suddenly think of the past to do Baidu app when there is this section of code, I do not know whether it can? The results are successful! This is the status of feedback to Baidu, let Baidu judge if the phone in the access to jump into the mobile phone version, if not then into the Internet version, in fact, is a remote judgment statement.
