How important is it to canonicalize mobile URLs to desktop URLs?

[nicole.healthline]

I know many SEO's prefer a stylesheet and single URL, but if you use m.domain.com, do you canonicalize to your desktop URLS?

To kind of summarize, Google has normal bot and mobile bot. So long as you're serving up data consistently you should be fine.

I would block m.domain.com from all crawlers except Googlebot-Mobile. At the same time, I would block domain.com from Googlebot-Mobile.

I hope that helps.
