Will editorial links with UTM parameters marked as utm_source=affiliate still pass link juice?

[Terakeet]

Occasionally some of our clients receive editorial mentions and links in which the author adds utm parameters to the outbound links on their blog. The links are always natural, never compensated, and followed.  However, they are sometimes listed as utm_source=affiliate even thought we have no existing affiliate relationship with the author.  My practice has been to ask the author to add a rel="norewrite" attribute to the link to remove any trace of the word affiliate.

I have read that utm parameters do not affect link juice transfer, however, given the inaccurate "affiliate" source, I wouldn't want Google to misunderstand and think that we are compensating people for followed editorial links.

Should I continue following this practice, or is it fine to leave these links as they are?

Thanks!

Thank you Eric.  It's definitely a gray area, I had considered your suggestion about requesting the author change the source parameter to something other than affiliate- and that's a great idea too.

I welcome more dialogue on this from others who may have some input.

I would think the parameters wouldn't count, but the root URL would (eg; search engines ignore anything after the "&" or "#" in the URL). I think Google devalues affiliate links, because those aren't "editorial" links - they're essentially paid links. It's really hard to say whether the links will be determined as "affiliate" by Google since the author is adding that in the tagging (that word may serve as a flag). My recommendation is to reach out and ask if they can change that URL tagging, since you're not an affiliate and don't want to be seen as one. UTM parameters are common for campaign tracking, and they don't influence the URL in terms of passing juice or whatever, so really you can put whatever you want. Those exist so you can define attribution models more effectively to learn what campaign provides the best ROI for your company/website.

I'd try to change that parameter, and maybe making the case that the author adding parameters like that to your URL is hurting your tracking (getting mixed in with real affiliates). It seems kind of weird to me that an author would add a tracking parameter like that without someone asking, but maybe that happens more than I realize.

Let me know how it works out - I haven't seen this case before so if others have experience I'd be interested to see how people have handled it in the past.
