All of our URLs in Google My Business are tagged with ?utm_source=gmb. This way when people click on it within a Google Map listing, knowledge graph, etc we know it came from there. I'm assuming using a canonical on all ?_utm_source _pages (we have others, including some in the index) won't cause any problems with this, correct? Since they're not technically traditional organic SERPs?

Dumb question I know, but better safe than sorry. Thanks.

Yeah, I'm trying to figure out the best way to present to them all the pertinent information regarding how terrible Shopify is. The way they use Collections then block any sort of parameters in their unalterable Robots.txt file is insane.
