Mobiles are becoming the trend of today. People no longer only rely on their desktop for any form of access or program usage, everything is made portable and available via your phone. This brings us to the question, how is Google utilizing this development?

During the last years, Google engineers had created and optimized Google bot algorithms on how it can crawl, index, and rank web pages. Google is on its way to greater mobile developments with the rise of the phone era and for those who don’t have a mobile site yet, don’t freak out, Google said they would continue to index your desktop, even if they were using a mobile user agent to view your site. This brings us to the point of the mobile first index system.

So what exactly is the mobile first index update?

The mobile first index means Google will start ranking both the desktop and mobile version of a website based on the mobile version itself. Google said they were still in the process of experimenting their index mobile first, although for now their search index will continue to be a single index of website and apps. That said, even though their index will be built from the mobile document, Google said they would still ensure a great search experience for all users – whether mobile or desktops.

So the concept of the mobile first index includes using the right algorithms that will eventually use primarily the mobile version of a site’s content to rank pages from that site in order to understand structured data and to show snippets from those pages on the Google search results.

Mobile version types

Some websites show their mobile version via responsive design, meaning both desktop and mobile sites use the same HTML file and the CSS is adjusted based on the device type browsing the site.

Other types include websites with separate versions for mobile and is usually hosted as a subdomain, such as m.example.com. If users reach the website from a smartphone, it will be automatically redirected to the mobile version. Whichever version you’re using for your site, you should optimize your website for this new update!
