Google Ignoring Canonical Tag for Hundreds of Sites
-
Bazaar Voice provides a pretty easy-to-use product review solution for websites (especially sites on Magento): https://www.magentocommerce.com/magento-connect/bazaarvoice-conversations-1.html
If your product has over a certain number of reviews/questions, the plugin cuts off the number of reviews/questions that appear on the page.
To see the reviews/questions that are cut off, you have to click the plugin's next or back function. The next/back buttons' URLs have a parameter of "bvstate....."
I have noticed Google is indexing this "bvstate..." URL for hundreds of sites, even with the proper rel canonical tag in place.
Here is an example with Microsoft:
My website is seeing hundreds of these "bvstate" urls being indexed even though we have a proper rel canonical tag in place. It seems that Google is ignoring the canonical tag. In Webmaster Console, the main source of my duplicate titles/metas in the HTML improvements section is the "bvstate" URLs.
I don't necessarily want to block "bvstate" in the robots.txt as it will prohibit Google from seeing the reviews that were cutoff. Same response for prohibiting Google from crawling "bvstate" in Paramters section of Webmaster Console.
Should I just keep my fingers crossed that Google honors the rel canonical tag?
Home Depot is another site that has this same issue:
-
I have had something similar, this is response I received:
You don’t have canonical tags on the URL and that’s expected.
On pages where BVSEO is implemented, canonical tags must be updated or removed when the product contains more than one page (more than eight) of reviews. BVSEO paginates the product page so all reviews are in the search engines’ index. Canonical tags that point away from a pagination URL will cause search engines to ignore the paginated content.
When any of the BVSEO pagination parameters are present (bvstate, bvrrp, bvqap, bvsyp, bvpage), do one of the following:
•Remove the canonical tag. This is the most common, recommended solution.
•Append the "name=value" pair to the canonical URL.
-
I think I found out what is going on.
I have found that the source code does contain the proper rel canonical tag.
However, the "bazaar voice" plugin generates a code snippet that appears in the page's body where it features a [base_url]. The [base_url] should match up with the canonical tag. For some reason, it isn't. The [base_url] that is generated contains the "bvstate" parameter.
Tools like the Mozbar, and I believe even Googlebot, are extracting out overriding the rel canonical tag with the [base_url] that appears in the code.
Complex!
-
Yeah, it's very strange... if you view-source on the BVSTATE url that is cached, the proper canonical tag is in there. Don't know why toolbar apps like Mozbar show otherwise. I think you're right, must be a deeper issue.
-
I just ran this query for bvstate URLs indexed for the H&R Block site. Mozbar shows canonical tags with bvstate in them, and Screaming Frog finds no canonical tags at all. There is a deeper issue that is not simply Google ignoring them.

Hey Logan -
The Microsoft canonical is not being obeyed. The canonical tag points to the one representative URL for the product whereas the "bvstate" URL is shown as being cached.
If you do a search in Google for inurl:"bvstate" , you will see hundreds of sites like H&R Block, Kohls, etc.
-
Do you have different examples? The Home Depot link doesn't work when trying to view the actual page on the site. With the Microsoft link, the canonical is working, as the version with the parameter is not indexed in Google, but the canonical version is indexed, which is what I would expect for a canonical that is being obeyed.

Trying to get Google to stop indexing an old site!
Howdy, I have a small dilemma. We built a new site for a client, but the old site is still ranking/indexed and we can't seem to get rid of it. We setup a 301 from the old site to the new one, as we have done many times before, but even though the old site is no longer live and the hosting package has been cancelled, the old site is still indexed. (The new site is at a completely different host.) We never had access to the old site, so we weren't able to request URL removal through GSC. Any guidance on how to get rid of the old site would be very appreciated. BTW, it's been about 60 days since we took these steps. Thanks, Kirk

Google Adding Wrong Location to Title Tag on Multi-Branch Business Homepage
We're a business with 5 separate locations across 5 cities in Upstate NY. While doing some visual ad previews in the adwords interface I noticed that Google is altering my title tag and adding the word "Rochester" to the end of it, cutting short my designated title tag. Rochester is the location of our headquarters so not a big deal for 1/5th of our customers. But to my dismay, the same thing is happening when searching from the geo locations of my other branches. So when searching for my business in Buffalo (we have a physical address in Buffalo), the title tag in the results still says our company name and "Rochester". This of course is likely leading to confusion and actively harming our organic CTR in our branch locations. This is happening in all of the remaining 4 branch locations. I'm at a loss, I tried lengthening the title tag but it still gets cut off. The term Rochester appears (as do the other branch locations) in my meta description for the homepage as well as in the text of the page itself. I haven't gone so far as to remove that yet and hopefully don't have to. Does anyone have any ideas? Thank you in advance!

Does blocking foreign country IP traffic to site, hurt my SEO / US Google rankings?
I have a website is is only of interest to US visitors. 99% (at least) of Adsense income is from the US. But I'm getting constant attempts by hackers to login to my admin account. I have countermeasures fo combat that and am initiating others. But here's my question: I am considering not allowing any non US, or at least any non-North American, traffic to the site via a Wordpress plugin that does this. I know it will not affect my business negatively, directly. However, are there any ramifications of the Google bots of these blocked countries not being able to access my site? Does it affect the rankings of my site in the US Google searches. At the very least I could block China, Russia and some eastern European countries.

Are pages with a canonical tag indexed?
Hello here, here are my questions for you related to the canonical tag: 1. If I put online a new webpage with a canonical tag pointing to a different page, will this new page be indexed by Google and will I be able to find it in the index? 2. If instead I apply the canonical tag to a page already in the index, will this page be removed from the index? Thank you in advance for any insights! Fabrizio

Getting Google to Correct a Misspelled Site Link...Help!
My company website recently got its site links in google search... WooHoo! However, when you type TECHeGO into Google Search one of the links is spelled incorrectly. Instead of 'CONversion Optimization' its 'COversion Optimization'. At first I thought there was a misspelling on that page somewhere but there is not and have come to the conclusion that Google has made a mistake. I know that I can block the page in webmaster tools (No Thanks) but how in the crap can I get them to correct the spelling when no one really knows how to get them to appear in the first place? Riddle Me That Folks! sitelink.jpg
