Simply put, Google will begin to index and rank your site based on the content on your mobile experience, and not your desktop experience as it has done historically. If you have a responsive site or a dynamic serving site where the primary content and markup is equivalent across mobile and desktop, you shouldn’t have to change anything.
If you have a site configuration where the primary content and markup is different across mobile and desktop, you should consider making some changes to your site.

Key Takeaways:

  • Google is implementing its website indexing system because more than half of web searches now come from mobile devices.
  • If a business wants their website to be ranked higher in the Google Indexing system, they need to make sure that their website is formatted to be optimal for mobile devices.
  • Making a website optimized for mobile devices includes ensuring that any links on your page got to mobile-friendly sites, there is no adobe flash, icons are larger, etc.


“Google has also added a “Mobile Usability” report on the Webmasters Tools Search Console. The report will pick up any elements of your website that do not function correctly or appear unnatural to users.”
