Some Blogger themes offer an option to specify how mobile clients should be served:
As far as I can tell, this doesn't override Blogger's redirecting behaviour, so mobile clients still get sent along to the URL with ?m=1 appended.
(NB: If you scan the QR code you might land at a preview for one of my other blogs).
Google indexes "mobile first" in a way that makes default / desktop view unreachable.
Update - even with applying a responsive design layout on a completely new site, Blogger insists on treating mobile clients to a redirect, which results in Google penalising the blog author by not indexing.
This is an interesting situation, as it is apparent that other search engines such as Bing will now be superior to Google as they pick up on a broader range of information.
