There are ways by which you can make smartphone users land up on the mobile version of your website and direct the desktop users to the desktop version. Google's Head of Search Spam, Matt Cutts discussed in the recent Webmaster Help video, how webmasters can optimize for the mobile web.
The question posted was:
Is there a way to tell Google there is a mobile version of a page, so it can show the alternate page in mobile search results? Or similarly, that a page is responsive and the same URL works on mobile?
To this, Cutts replied, that there are a number of ways by which webmasters can go ahead with the issue:
- Separate Versions of Website for Mobile and Desktop: Matt suggests to have separate URLs for mobile and desktop versions of the website. You can do this by branding the desktop version with rel=”alternate” and the mobile version with rel=”canonical”. With the bi-directional links Google can direct the users to the right destination.
- Redirecting Smartphone Agents: Redirecting the smartphone agents from the desktop version to the smartphone version can also resolve the issue. According to Matt, webmasters should ensure that googlebot is not blocked so that it can return the correct URLs to the users. To make it simpler, you just have to treat Googlebot as a desktop user and Googlebot Mobile as a smartphone user.
By following these simple steps webmasters can let Google distinguish between the mobile and desktop versions of their website.
