In the mobile-first era, it is certainly crucial to have effective search engine optimization (SEO). Most people use a mobile device to access the internet. In fact, about 50 percent to 60 percent of search queries come from smartphones and tablets. As the majority of search requests increase by mobile device, Google will be switching to mobile-first indexing in the near future. This was announced in 2016 during an interview with Garry Illyes, a well-known Google webmaster trends analyst. Illyes informed that, even though Google had not set any specific dates, the mobile-first shift is expected to happen in early 2018.
 
However, a large number of phone users complain that a bad phone surfing experience has made them less likely to engage with certain websites. It’s important to make sure your business would not be left behind by not optimizing your websites for smartphones and tablets. Google has introduced a very crucial transition to the mobile-first index to improve the experience of phone users. Right now, Google indexes a website based on its desktop version to rank both the phone and desktop version, but with the implementation of the mobile-first index, this will be going to change and for good reasons.
 
Soon, Google will crawl similar to a mobile user's point of view and will catalog sites according to the mobile phone version. But, these updates will be implemented slowly and the changes would not be noticed externally at the start. If you are using a responsive design for the site, you should be aware about this update. While mobile-friendly sites work the same way across all devices, responsive ones are altered according to the size of the screen. Moreover, desktop and phone version of a site generally have similar content being easily accessed on both devices. However, if you are using different content on mobile sites or using different mobile URLs by means of dynamic serving, then you should be very attentive.
 
A responsive design will offer you many benefits such as improved usability, lower bounce rates, less duplicate content and more. With the rise of mobile-first indexing, webpage loading speed will become the main deciding cause in driving quality customers to your website and getting them converted. In fact, Google has been experimenting with this latest update for quite some time and you will surely get quality output from this update.
