How Google’s Mobile Only Index change with SEO

Google gathers information about every web page in a massive catalog, which is known as an index, that display search results for various queries. Now, Google is treating the mobile versions of each page as the primary page to index, with desktop versions being secondary, though priority was given to desktop searches earlier.

You will get affected by the mobile-first indexing if your mobile and desktop sites are significantly different. As an example, if the mobile version of a page of your website has significantly small content than the desktop version, the mobile will now be treated as the original version. Mobile-first is also important because it repeats Google’s commitment to appealing to mobile users.
It’s clear that Google is building a new future for mobile content and mobile users with these rollouts. Fortunately, the mobile-first index doesn’t give a huge impact on your SEO strategy in a major way. You can consider the following for better SEO Strategy;

Ensure full mobile compliance. Make sure you have a fully functioning mobile version of your website, preferably by using a responsive design on the site that automatically flexes based on the device used to access it. Ensure equivalence between desktop and mobile versions. But in case if you do end up using a separate mobile version of your website, you’ll want to provide complete identity between your two versions. Make your mobile version your main version, and make sure it’s always updated first in future revisions.

Consider app development. By mobile-first is focused on mobile sites, not apps, it’s worth it to consider developing an app for your business.
The mobile-first index may not impact your site directly, but it’s important to recognize its effects, and what it means for the direction and priorities of the search engine giant. Maintain prioritizing your mobile users, and you’ll remain on Google’s safe side.
