Did you see ? Google is saying goodbye to the desktop version.
Mobile-First Indexing at Google is becoming the default later this year. Googlebot is leaving its desktop behind, and using a phone, like most of our users.
Why ?
Most websites are mobile ready
70 % of websites in search results have a mobile version
Google will switch to mobile first from September 2020
Google will occasionally scan your website with desktop Google bot. But don't get your hopes high
If a domain moves to mobile indexing ( if not already ), the crawling process will take some time for mobile first crawling
Search console and URL inspection tool will help you move to mobile first indexing
Google recommends responsive design for new websites
Mobile URLs are not welcome. Because they create confusion for users and search engines ( according to Google )
