Google’s John Mueller clarified the longstanding confusion about whether or not it’s acceptable to make use of a noindex rule and a canonical tag on the identical web page. A 2021 assertion instructed that utilizing each may ‘possibly’ work, however his newest assertion offers a extra detailed and definitive reply.
Noindex Rule And Rel=Canonical
An HTML factor is sort of a constructing block of an online web page. An attribute (like rel=canonical) is one thing that modifies the factor with extra data.
Google’s documentation states:
“rel=”canonical” hyperlink annotations: A powerful sign that the desired URL ought to change into canonical.”
Right here is how the noindex and canonical are alleged to work:
- The noindex rule is a directive that Google should obey.
- The rel=canonical is a “robust sign” that may be ignored.
The conundrum is that the noindex seemingly cancels out the canonical as a result of in idea Google received’t see it. So if Google can’t see the canonical then why did John Mueller beforehand say in a 2021 video that it’s okay to make use of each?
What Mueller Stated In 2021
The particular person asking the query cited an search engine optimization Workplace Hours Hangout YouTube video from 2021 the place Mueller had really helpful utilizing both the canonical or the noindex rule, explaining the variations. However then later he hedged and stated that both noindex and canonical can be used at the same time however qualifying that assertion by saying that “possibly” Google may ahead the canonical sign, thereby maintaining a web page out of the index whereas additionally canonicalizing the popular net web page.
That is the a part of the 2021 video of Mueller that the particular person asking the query referred to:
“…you can even do each of them.
And it’s one thing… if exterior hyperlinks, for instance, are pointing at this web page then having each of them there type of helps us to determine effectively, you don’t need this web page listed however you additionally specified one other one.
So possibly a few of the alerts we are able to simply ahead alongside.”

As you’ll be able to see above, John Mueller certified his assertion with a “possibly” which means that it’s not an absolute black and white assertion however relatively an announcement that’s coloured with shades of grey. Mueller didn’t clarify why he used the phrase “possibly” when he answered but it surely’s a nuance that’s price noting.
Is It Okay To Use Noindex & Canonical Tag?
That is the query that was requested on Reddit:
“Hello u/johnmu I used to be watching this …the place you advise utilizing noindex and canonical tags on the identical time.
Are you able to please verify if that is nonetheless legitimate and in case noindexed web page has canonical tag you’ll ahead backlink alerts to the canonical model?
For instance CNN hyperlinks to /t-shirt/grey/?worth=50 web page which is noindexed. One can add canonical tag /t-shirt/grey/ alongside with noindex and google could ahead CNN hyperlink sign to the canonical model.
thanks”
John Mueller Solutions Noindex & Canonical Query:
Mueller supplied a extra absolute reply by affirming that it’s finest to select one or the opposite, explaining {that a} noindexed canonical may nor won’t be picked up by Google, thereby explaining why he stated “possibly” within the 2021 YouTube Video.
He wrote:
“…I’d simply decide one (noindex or adopted hyperlinks). Hyperlinks on a noindexed web page will be picked up, but it surely’s not assured. search engine optimization is commonly about making your choice very clear and never about possibly’s. Additionally, it’s useful to be sensible: typically (typically) having web site construction that typically works effectively for search engines like google is healthier than hyper-focusing on hyperlinks (or every other particular person side of search engine optimization).”
Mueller’s Reply Explains Use Of Noindex & Canonical
His reply explains rather a lot and clears up why he hedged in 2021 with a “possibly” whereas not precisely moving into the main points of why Google could or could not decide up a canonical when a noindex rule is invoked.
For individuals who need slightly extra element about why Mueller stated the canonical is perhaps picked up, there’s a tweet from 2020 by Google’s Gary Illyes through which he explains the technical purpose why Google may see hyperlinks when there’s a noindex in place.
A nerdy element is that the one that tweeted the query in 2020 was asking a few robots meta noindex with a “comply with” directive however the factor is that there is no such thing as a such factor as a “comply with” directive, in line with Google’s robots meta tag documentation. The explanation there’s no such factor as a “comply with” directive is as a result of following hyperlinks is the default Googlebot habits.
Gary tweeted:
“one thing with noindex won’t ever attain the serving index, however we can have the fetched copy for issues like hyperlink graph calculation.”
A “link graph” calculation is a reference to the (reduced) link graph of internet sites that could be a map of the link relationships between pages and websites.
