Mobile-first indexing means Google predominantly uses the mobile version of the content for indexing and ranking. Since the majority of users now access Google Search with a mobile device, Googlebot primarily crawls and indexes pages with the smartphone agent going forward.
Starting July 1, 2019, mobile-first indexing is enabled by default for all new websites, and here are two things to keep in mind:
1 – Make sure your mobile site reflects your full content because Google won’t use the desktop version at all once they switch your site over.
2 – If you use separate mobile URLs (commonly called m-dot URLs), make sure to use them consistently within your structured data too. Google won’t spend a nanosecond trying to figure out why things aren’t the same, just on to the next.
