Hi friends,
What is mobile first indexing?

Mobile-first indexing means Google will predominantly use the mobile version of the content for indexing and ranking. ... We will continue to show the URL that is the most appropriate to users (whether it's a desktop or mobile URL) in Search results.

Really impressive information you shared, thanks for giving such information

Hello,
Mobile-first indexing means Google predominantly uses the mobile version of the content for indexing and ranking. Historically, the index primarily used the desktop version of a page's content when evaluating the relevance of a page to a user's query.
