There are four common types of redirects that affect how your users and Google see your mobile pages. Each of them is bad for performance (speed). They include:
* Initial redirect – canonical (www.example.com vs example.com)
- SSL – secure pages redirect
- Redirect to mobile version
- Content driven redirects
Redirect to mobile version
When you have a different web address (url) for your mobile pages than you do for your desktop pages, the mobile device must somehow get to the mobile version. The way it does so is through a redirect.
In other words, the mobile redirect is the method in which your mobile page gets displayed.This redirect only occurs when a different url is utilized for mobile devices versus the desktop version. This redirect does not happen when a responsive web design is employed.
As previously mentioned, a mobile redirect only occurs when a different url is utilized for mobile devices versus the desktop version.
Using responsive web design or dynamic serving will remedy this issue by eliminating the need for separate urls for the same website (i.e., mobile v. desktop version).
