You have probably been hearing about a new feature that Google has been buzzing around the 
Here are a few recommendations to help webmasters prepare as Google moves towards a more mobile-focused index.
- 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.
- Make sure to serve structured markup for both the desktop and mobile version.
- Sites can verify the equivalence of their structured markup across desktop and mobile by typing the URLs of both versions into the Structured Data Testing Tool and comparing the output.
- When adding structured data to a mobile site, avoid adding large amounts of markup that isn’t relevant to the specific information content of each document.
- Use the txt testing tool to verify that your mobile version is accessible to Googlebot.
- Sites do not have to make changes to their canonical links; we’ll continue to use these links as guides to serve the appropriate results to a user searching on desktop or mobile.
- If you are a site owner who has only verified their desktop site in Search Console, please add and verify your mobile version.
- If you only have a desktop site, we’ll continue to index your desktop site just fine, even if we’re using a mobile user agent to view your site.
