In view of the surging tide of mobility and the H5 of the page, Baidu introduced the best solution for PC page and H5 page's Jump Fit method:
1. On the PC version of the webpage, add a special link to the corresponding mobile URL rel= "Alternate" tag, which helps Baidu to find the site of the mobile version of the page location;
2. Also on the mobile page, add a link to the corresponding PC version of the URL rel= "canonical" tag.

Mobile Website:

If your URL is:
PC version URL: http://pc_url
Mobile URL: Http://mobile_url

Then the comments in this example are as follows:
On the PC version page (http://pc_url), add:

<link rel= "Alternate" media= "only screens and (max-width:640px)" href= "Http://pc_url" >

On the mobile page (Http://mobile_url), the required comments should be:

<link rel= "canonical" Href= "Http://mobile_url" >

The previous META tag (mobile agent) will continue, but we recommend using the HTMAL5 language to make mobile pages with the latest scheme for jump adaptation, other such as the XML language mobile page jump adaptation, need to continue to use the previous meta tag way:

<meta name= "mobile-agent" content= "FORMAT=[WML|XHTML|HTML5"; Url=mobile_url ">
