What could cause Google to not honor canonical URLs?
-
I have a strange situation on a website, when I do a Google query of site:example.com all the top indexed results appear to be queries that users can perform on the website. So any random term the user searches for on the website for some reason is causing the search result page to get indexed - like example.com/search/query/random-keywords
However, the search results page has a canonical tag on it that points to example.com/search, but that doesn't seem to be doing anything. Any thoughts or ideas why this could be happening?

Hi there,
First of all, its a mistake to think that when searching with _site: _operator, the first results are the most important nor the more relevant. Google has said a few times that we shouldn't rely that much on what that search in terms of what's being shown.
Blocking search results with robots.txt wont be of help, as it will not remove already indexed pages and cant prevent for new pages to be indexed (if there's an external link to a robots.txt blocked page, google can still index it) it'll only prevent Googlebot from discovering new ones FROM YOUR SITE.
Again, i'd try to dig deeper to understand where are the links to internal searches that google is finding. Googlebot will not do any search in your site.
The thing with GSC, might be related to quite a few reasons. I cant say much because I don't know any more specifics, but from what you are telling me it looks like you are getting impressions in searches that you don't relate to your site and that land on pages that google is noindexing. Yeah im repeating the obvious, hehe.
In my experience, Google can have these strange behaviours. You know, there are cases when a page is canonicalized, but it can still be shown in SERPS. Dont ask me why, but it happens. It takes a little time to google fully replace it with the correct one.
I'd wait a little longer to see how Google is handling them.I don't know if im helping you.
it kinda took me a few minutes to understand/process what you wrote and come up with an answer.Please, feel free ask again or comment on my reply if I misunderstood something.
Best luck,

Hi here's some more background info on this situation that makes it even stranger. I can perform some pretty specific searches on Google where these indexed search result pages show up. And I can look in Google Search Console under the performance section and see that those pages receive impressions and clicks. However, if I inspect the URL, Search Console says it is not included in Google's index, and the reason it gives under indexing is because it says it is honoring the canonical URL. So search console is saying it isn't indexed because of the canonical, but I can do searches and find that exact URL in the index. Any ideas what this could be from?

Hi Gaston,
Thanks for the response. I can confirm that the example, /search and /search?q=foo are pretty much identical. However that may not always be the case, only when a user searches for something that would return no results. So, a website that sells widgets, /search and /search?q=widgets would not be identical, and in that case it would make sense that Google would not honor the canonical link. What's really strange is if I search google for the site: operator of the domain, the top pages are not user queries for things that make sense. The top indexed pages are random, non-relevant user searches.
I do not have a way with this system to control noindex tags on these search result pages. The only thing I could do is take the nuclear option and just block it all with robots.txt using wildcards. But that means no search result pages would get indexed, relevant or not.

Hi there,
in my experience, when google doesn't honor Canonicals, is because pages arent similar.
In its definition, canonical are there for two or more pages that have the same content.If you are finding it problematic, i'd suggest to use noindex tags for that search pages.
I'd investigate If there are links pointing to those internal search pages, as its not common for google to discover search pages.Hope it helps,
Best luck.
Gaston

Does Google read dynamic canonical tags?
Does Google recognize rel=canonical tag if loaded dynamically via javascript? Here's what we're using to load: <script> //Inject canonical link into page head if (window.location.href.indexOf("/subdirname1") != -1) { canonicalLink = window.location.href.replace("/kapiolani", ""); } if (window.location.href.indexOf("/subdirname2") != -1) { canonicalLink = window.location.href.replace("/straub", ""); } if (window.location.href.indexOf("/subdirname3") != -1) { canonicalLink = window.location.href.replace("/pali-momi", ""); } if (window.location.href.indexOf("/subdirname4") != -1) { canonicalLink = window.location.href.replace("/wilcox", ""); } if (canonicalLink != window.location.href) { var link = document.createElement('link'); link.rel = 'canonical'; link.href = canonicalLink; document.head.appendChild(link); } script>

Category URL Pagination where URLs don't change between pages
Hello, I am working on an e-commerce site where there are categories with multiple pages. In order to avoid pagination issues I was thinking of using rel=next and rel=prev and cannonical tags. I noticed a site where the URL doesn't change between pages, so whether you're on page 1,2, or 3 of the same category, the URL doesn't change. Would this be a cleaner way of dealing with pagination?

301 redirect: canonical or non canonical?
Hi, Newbie alert! I need to set up 301 redirects for changed URLs on a database driven site that is to be redeveloped shortly. The current site uses canonical header tags. The new site will also use canonical tags. Should the 301 redirects map the canonical URL on the old site to the corresponding canonical for the new design . . . or should they map the non canonical database URLs old and new? Given that the purpose of canonicals is to indicate our preferred URL, then my guess is that's what I should use. However, how can I be sure that Google (for example) has indexed the canonical in every case? Thx in anticipation.

Google Cache showing a different URL
Hi all, very weird things happening to us. For the 3 URLs below, Google cache is rendering content from a different URL (sister site) even though there are no redirects between the 2 & live page shows the 'right content' - see: http://webcache.googleusercontent.com/search?q=cache:http://giltedgeafrica.com/tours/ http://webcache.googleusercontent.com/search?q=cache:http://giltedgeafrica.com/about/ http://webcache.googleusercontent.com/search?q=cache:http://giltedgeafrica.com/about/team/ We also have the exact same issue with another domain we owned (but not anymore), only difference is that we 301 redirected those URLs before it changed ownership: http://webcache.googleusercontent.com/search?q=cache:http://www.preferredsafaris.com/Kenya/2 http://webcache.googleusercontent.com/search?q=cache:http://www.preferredsafaris.com/accommodation/Namibia/5 I have gone ahead into the URL removal Tool and got denied for the first case above ("") and it is still pending for the second lists. We are worried that this might be a sign of duplicate content & could be penalising us. Thanks! ps: I went through most questions & the closest one I found was this one (http://moz.com/community/q/page-disappeared-from-google-index-google-cache-shows-page-is-being-redirected) but it didn't provide a clear answer on my question above

Using the Google Remove URL Tool to remove https pages
I have found a way to get a list of 'some' of my 180,000+ garbage URLs now, and I'm going through the tedious task of using the URL removal tool to put them in one at a time. Between that and my robots.txt file and the URL Parameters, I'm hoping to see some change each week. I have noticed when I put URL's starting with https:// in to the removal tool, it adds the http:// main URL at the front. For example, I add to the removal tool:- https://www.mydomain.com/blah.html?search_garbage_url_addition On the confirmation page, the URL actually shows as:- http://www.mydomain.com/https://www.mydomain.com/blah.html?search_garbage_url_addition I don't want to accidentally remove my main URL or cause problems. Is this the right way this should look? AND PART 2 OF MY QUESTION If you see the search description in Google for a page you want removed that says the following in the SERP results, should I still go to the trouble of putting in the removal request? www.domain.com/url.html?xsearch_... A description for this result is not available because of this site's robots.txt – learn more.

Blocked URL parameters can still be crawled and indexed by google?
Hy guys, I have two questions and one might be a dumb question but there it goes. I just want to be sure that I understand: IF I tell webmaster tools to ignore an URL Parameter, will google still index and rank my url? IS it ok if I don't append in the url structure the brand filter?, will I still rank for that brand? Thanks, PS: ok 3 questions :)...

Do canonical tags pass all of the link juice onto the URL they point to?
I have an ecommerce website where the category pages have various sorting and paging options which add a suffix to the URLs. My site is setup so the root category URL, domain.com/category-name, has a canonical tag pointing to domain.com/category-name/page1/price however all links, both interner & external, point to the former (i.e. domain.com/category-name). I would like to know whether all of the link juice is being passed onto the canonical tag URL? Otherwise should I change the canonical tag to point the other way? Thanks!

Trailing Slashes In Url use Canonical Url or 301 Redirect?
I was thinking of using 301 redirects for trailing slahes to no trailing slashes for my urls. EG: www.url.com/page1/ 301 redirect to www.url.com/page1 Already got a redirect for non-www to www already. Just wondering in my case would it be best to continue using htacces for the trailing slash redirect or just go with Canonical URLs?
