Okay to have additional attributes in canonical tag?

[PattyAMG]

Hello!

I'm helping a Client with a platform migration from an SEO standpoint.  They are working to implement canonical tags, but I've noticed that each of the ones they are implementing are including a "data-rdm" attribute:

data-rdm="">

I'm not sure the Client has a way to suppress this before the launch date.  Do we think this will be an issue for Google?

As long as you are inserting the canonical tag and pointing to the right URL, then there shouldn't be any issue with the additional attributes. As long as the attributes don't affect Google, then it should safely ignore them.

You can try some A/B testing if you wish, but in other cases of adding attributes, Google just applies the tags that it recognises/reads.
