Last year Google introduced a new mobile user agent for Googlebot-Mobile Smartphones, which was responsible for detecting mobile content. Google is now finally offering specific recommendations on which way to build your mobile sites. While there are various methods of having a mobile ready/friendly site, their preferred method of choice is Mobile Responsive. Why a responsive design? From Google’s Developer’s site…
We recommend using responsive web design because it has many good aspects:
- Using a single URL for a piece of content makes it easier for your users to interact with, share, and link to your content, and a single URL for the content helps Google’s algorithms assign the indexing properties for the content.
- No redirection is needed for users to get to the device-optimized view, which reduces loading time. Also, user agent-based redirection is error-prone and can degrade your site’s user experience (There are pitfalls when detecting user agents.)
- It saves resources for both your site and Google’s crawlers. For responsive web design pages, any Googlebot user agents needs to crawl your pages once, as opposed to crawling multiple times with different user agents, to retrieve your content. This improvement in crawling efficiency can indirectly help Google index more of the site’s contents and keep it appropriately fresh.
