Do URLs with canonical tags get indexed by Google?
-
Hi, we re-branded and launched a new website in February 2016. In June we saw a steep drop in the number of URLs indexed, and there have continued to be smaller dips since. We started an account with Moz and found several thousand high priority crawl errors for duplicate pages and have since fixed those with canonical tags. However, we are still seeing the number of URLs indexed drop.
Do URLs with canonical tags get indexed by Google? I can't seem to find a definitive answer on this. A good portion of our URLs have canonical tags because they are just events with different dates, but otherwise the content of the page is the same.

Thanks so much! Really helpful!

Not exactly. Its not so much that the canonical "supersedes" an index, follow tag.... a canonical tag establishes equivalency while a NoIndex is more like a "does not equal." The Index, Follow is still there and being seen by bots as they crawl... in fact, if you had NoIndex on a page with a Canonical Tag, it may not even see the canonical at all since you told it to NoIndex the page. The Meta Robots Index tag comes first allowing the bots to crawl and index the page but then the canonical sets up equivalency to a separate page. So if your canonical tag is being respected, it doesn't wind up doing the same thing as a NoIndex (though it may seem that way) nor does it do the same thing as a 301 (though there are similarities in how equity is passed). Since a canonical establishes an equivalency, you'll find that the Canon Page will eventually take the place of the Canonicalized Page in search results because you're telling them the Canonicalized Page _is _the Canon Page & that the Canon page is the right version of both.

Thanks, Mike! So, just to clarify, for a particular URL, if we have Meta Robots set to "Index/Follow" and that same URL has a canonical tag, the canonical tag would supersede the robot command and the URL would not be indexed?

If a URL was indexed and has since had a canonical added to it pointing to another page, it will eventually disappear from results. Basically the pages gets consolidated with its canon page. If the bots choose to respect the canonical tag in that instance, all signals get passed to the canon page while still allowing the page and information to be accessible by human visitors. As such, there's no reason to keep the page in the index because you're telling the bots that another page is the correct page instead. This is not the same as NoIndexing a page but will eventually remove a page from the index much in the same way that a 301 will pass equity along to another page while eventually removing the redirected page from the index in favor of the page being redirected to.

Duplicate, submitted URL not selected as canonical
Hi all, A number of our pages have dropped out of search rankings. It seems they are being marked as "Duplicate, submitted URL not selected as canonical" However, the page Google is choosing as the canonical is totally different - different headings, titles, metadata, content on the page. We are completely mystified as to why this is happening. If anyone can shed any light, it would be hugely appreciated! Example URL is this one:

Google not Indexing images on CDN.
My URL is: https://bit.ly/2hWAApQ We have set up a CDN on our own domain: https://bit.ly/2KspW3C We have a main xml sitemap: https://bit.ly/2rd2jEb and https://bit.ly/2JMu7GB is one the sub sitemaps with images listed within. The image sitemap uses the CDN URLs. We verified the CDN subdomain in GWT. The robots.txt does not restrict any of the photos: https://bit.ly/2FAWJjk. Yet, GWT still reports none of our images on the CDN are indexed. I ve followed all the steps and still none of the images are being indexed. My problem seems similar to this ticket https://bit.ly/2FzUnBl but however different because we don't have a separate image sitemap but instead have listed image urls within the sitemaps itself. Can anyone help please? I will promptly respond to any queries. Thanks

How google crawls images and which url shows as source?
Hi, I noticed that some websites host their images to a different url than the one their actually website is hosted but in the end google link to the one that the site is hosted. Here is an example: This is a page of a hotel in booking.com: http://www.booking.com/hotel/us/harrah-s-caesars-palace.en-gb.html When I try a search for this hotel in google images it shows up one of the images of the slideshow. When I click on the image on Google search, if I choose the Visit Page button it links to the url above but the actual image is located in a totally different url: http://r-ec.bstatic.com/images/hotel/840x460/135/13526198.jpg My question is can you host your images to one site but show it to another site and in the end google will lead to the second one?

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 :)...

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?
