For all those considering to moving their mobile sites, a.k.a ‘m-dot’ towards responsive web design, Google has some recommendations for webmasters to make a move in a way that gives the sites chance to perform well on search results.
As Google in next few months will implement mobile fist index, it recommends once your responsive site is ready, all you need to do is “configure 301 redirects from the mobile URLs to the responsive web URLs,” so your URLs stay the same for destop and mobile version.
See this diagram showing a 301 redirect from m-dot to responsive:
Those of you currently using dynamic serving, don’t need to add or change any redirects to move to responsive design.
Here are the detailed steps published by Google to move m-dot URLs to responsive:
- Get your responsive site ready
- Configure 301 redirects on the old mobile URLs to point to the responsive versions (the new pages). These redirects need to be done on a per-URL basis, individually from each mobile URLs to the responsive URLs.
- Remove any mobile-URL specific configuration your site might have, such as conditional redirects or a vary HTTP header.
- As a good practice, setup rel=canonical on the responsive URLs pointing to themselves (self-referential canonicals).
