As explained on searchengineland.com, mobile-first indexing is simply how Google crawls and indexes the web. Instead of looking at the desktop version of the page, Google looks at the mobile version of the page. In more simple terms, Google is crawling and indexing your web page based on how it renders on a mobile phone versus a desktop computer. Now over 50% of what Google indexes is indexed over mobile-first indexing.
Google announced that from 1st July 2019, all websites previously unknown to Google would be indexed using mobile-first indexing, rather than the old method of indexing where google would first look at the desktop version of your website, determine the score of your site based on a range of factors such as content and loading speed, then index.
So what does this mean?
This means that is it even more important to make sure that your website is operating seamlessly and as efficient as possible on mobile devices to ensure that you receive the best ranking possible from Google. If your website is slow and not great on mobile devices, you should look into updating your website as soon as possible, to avoid receiving any penalisation on ranking from Google.
