Mobile algorithm update

Google made an unprecedented announcement that it was splitting its desktop and mobile ranking algorithm from 21st of April. The announcement is unusual as it puts an exact date on an algorithm update.

This is the highlighted excerpt from Google webmaster central.


As an update Google Webmaster Trends Analyst John Mueller answered questions in the weekly webmaster central hangout.

Before now SEO experts were using the same practice for both desktop and mobile optimisation – SERP was SERP regardless of desktop or mobile platform. Google has always urged webmasters to make their website mobile friendly in view of the growing large shift of traffic from mobile devices. The announcement says that from 21st April non mobile friendly sites can expect a drop in rankings.

Any Effective on Desktop?

Whether or not this mobile algorithm update will have any effect on desktop remains unclear but many people think there is a link now or in the near future. What was also not clear is whether the mobile-friendly update will apply site-wide or on a page by page basis. The difference will be important to websites that have taken to Google’s preferred solution of dynamic website serving or separate mobile site. The distinction could be important to people knowing whether their site will be hit site-wide or just a few pages.

Responsive web design the way to go

What this means is that we cannot emphasise any more times about the importance of responsive design solutions. The problem is solved because responsive sites have an exact one-one relationship between desktop and mobile. This has been the stated preferred solution of Google so we can assume responsive design themed websites will see an immediate boost compared to other solutions. Google has also gone a long way in supporting webmasters to make their sites more mobile-friendly through schemes like Mobile Usability Report to Google Webmaster Tools. Google has released a mobile friendliness testing tool to further assist webmasters.

Chrome Developer Tools Emulation Mode

Testing our websites has become a complex exercise for webmasters. Back in the day it was complete after verifying functions of a couple of browsers. However new websites must now be tested on a variety of platforms including mobile, tablets, desktop devices as well as various operating systems and screen resolutions and capabilities – touch-screens and HD displays..

In some cases it can take the same amount of time as website development. Building code on just a PC will not allow you to appreciate the various other devices that consumers might consume media. The challenge is knowing how to test various systems without the need to switch amongst various devices.


Chrome Emulation mode

Happily the latest version of Chrome V32 ( has come to our aid with its new Emulation mode in developer mode.

Chrome Developer Tools Emulation Mode is not perfect so give it a go and perhaps test on real life devices as a double check.
