There’s an fascinating response from John Mueller of Google on what to do with URLs that will seem duplicated due to URL parameters, like UTMs, on the finish of the URLs. John mentioned undoubtedly do not 404 these URLs, which I believe nobody would argue with. However he additionally mentioned you should use the rel=canonical as a result of that was what it was made for. The kicker is he mentioned it in all probability does not matter both means for Website positioning.
Now, I needed to learn John’s response a few instances on Reddit and possibly I’m deciphering the final half incorrectly, so assist me out right here.
Right here is the query:
Howdy! New to the group however have been in Website positioning for ~5 years. Began a brand new job as the only real Website positioning supervisor and am fascinated with crawl funds. There are ~20k crawled not listed URLs in comparison with the 2k which might be crawled and listed – this isn’t because of error, however as a result of excessive variety of UTM/marketing campaign particular URLs and (deliberately) 404’d pages.
I hoped to stability out this crawl funds a bit and eradicating the UTM/marketing campaign URLs from being crawled through robots.txt and by turning a number of the 404s into 410s (would additionally assist with general website well being).
Can somebody assist me work out if this may very well be a good suggestion/might probably trigger hurt?
John’s 404 response:
Pages that do not exist ought to return 404. You do not achieve something Website positioning-wise for making them 410. The one cause I’ve heard that I can observe is that it makes it simpler to acknowledge unintended 404s vs recognized eliminated pages as 410s. (IMO in case your necessary pages unintentionally grow to be 404s, you’d in all probability discover that shortly whatever the consequence code)
John’s canonical response:
For UTM parameters I would just set the rel-canonical and depart them alone. The rel canonical will not make all of them disappear (nor would robots.txt), but it surely’s the cleaner strategy than blocking (it is what the rel canonical was made for, primarily).
Okay, to this point, don’t use 404s on this scenario however do use rel=canonical – bought it.
John then defined Website positioning clever, it in all probability does not matter?
For each of those, I think you would not see any seen change in your website in search (sorry, tech-Website positioning aficionados). The rel-canonical on UTM URLs is definitely a cleaner resolution than letting them accumulate & bubble out on their very own. Fixing that early means you will not get 10 generations of SEOs who inform you of the “duplicate content material downside” (which is not a problem there anyway if they don’t seem to be getting listed; and once they do get listed, they get dropped as duplicates anyway), so I suppose it is a good funding in your future use of time 🙂
So Google will doubtless deal with the duplicate URLs, the UTM parameters anyway, even when they do index them. However to make Website positioning consultants completely satisfied, use the rel=canonical? Is that what he’s saying right here? I do like that response, if that’s his message – however possibly I bought it mistaken?
