There has been a lot of talking about mobile-first indexing, as Google’s latest development in it’s efforts to make the web more friendly to every user across different devices of different screen sizes. All businesses should prepare for mobile-first indexing. But the question still remains ,what is mobile first indexing?
According to google,
Mobile-first indexing means Google predominantly uses the mobile version of the content for indexing and ranking. This means that Google is now crawling and indexing your website based on how responsive it is or how it can fits to any screen size of any mobile device.
Google also goes on to explain that:
Starting July 1, 2019, mobile-first indexing is enabled by default for all new websites (new to the web or previously unknown to Google Search). For older or existing websites, we continue to monitor and evaluate pages based on the best practices. We notify site owners through Search Console once they’re seen as being ready. Since the default state for new sites is mobile-first indexing, there’s no need to send a notification to new sites.
