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.

Move to new domain using Canonical Tag
At the moment, I am moving from olddomain.com (niche site) to the newdomain.com (multi-niche site). Due to some reasons, I do not want to use 301 right now and planning to use the canonical pointing to the new domain instead. Would Google rank the new site instead of the old site? From what I have learnt, the canonical tag lets Google know that which is the main source of the contents. Thank you very much!

Wrong country sites being shown in google
Hi, I am having some issues with country targeting of our sites. Just to give a brief background of our setup and web domains We use magento and have 7 connected ecommerce sites on that magento installation 1.www.tidy-books.co.uk (UK) - main site 2. www.tidy-books.com (US) - variations in copy but basically a duplicate of UK 3.www.tidy-books.it (Italy) - fully translated by a native speaker - its' own country based social medias and content regularly updated/created 4.www.tidy-books.fr (France) - fully translated by a native speaker - its' own country based social medias and content regularly updated/created 5.www.tidy-books.de (Germany) - fully translated by a native speaker - uits' own country based social medias and content regularly updated/created 6.www.tidy-books.com.au (Australia) - duplicate of UK 7.www.tidy-books.eu (rest of Europe) - duplicate of UK I’ve added the country and language href tags to all sites. We use cross domain canonical URLS I’ve targeted in the international targeting in Google webmaster the correct country where appropriate So we are getting number issues which are driving me crazy trying to work out why The major one is for example If you search with an Italian IP in google.it for our brand name Tidy Books the .com site is shown first then .co.uk and then all other sites followed on page 3 the correct site www.tidy-books.it The Italian site is most extreme example but the French and German site still appear below the .com site. This surely shouldn’t be the case? Again this problem happens with the co.uk and .com sites with when searching google.co.uk for our keywords the .com often comes up before the .co.uk so it seems we have are sites competing against each other which again can’t be right or good. The next problem lies in the errors we are getting on google webmaster on all sites is having no return tags in the international targeting section. Any advice or help would be very much appreciated. I’ve added some screen shots to help illustrate and happy to provide extra details. Thanks UK%20hreflang%20errors.png de%20search.png fr%20search.png it%20search.png

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.

Best way to implement canonical tags on an ecommerce site with many filter options?
What would be the best way to add canonical tags to an ecommerce site with many filter options, for example, http://teacherexpress.scholastic.com? Should I include a canonical tag for all filter options under a category even though the pages don't have the same content? Thanks for reading!

Splitting a Site into Two Sites for SEO Purposes
I have a client that owns a business that really could be easily divided into two separate business in terms of SEO. Right now his web site covers both divisions of his business. He gets about 5500 visitors a month. The majority go to one part of his business and around 600 each month go to the other. So about 11% I'm considering breaking off this 11% and putting it on an entirely different domain name. I think I could rank better for this 11%. The site would only be SEO'd for this particular division of the company. The keywords would not be in competition with each other. I would of course link the two web sites and watch that I don't run into any duplicate content issues. I worry about placing the redirects from the pages that I remove to the new pages. I know Google is not a fan of redirects. Then I also worry about the eventual drop in traffic to the main site now. How big of a factor is traffic in rankings? Other challenges include that the business services 4 major metropolitan areas. Would you do this? Have you done this? How did it work? Any suggestions?

Canonical Tag and Affiliate Links
Hi! I am not very familiar with the canonical tag. The thing is that we are getting traffic and links from affiliates. The affiliates links add something like this to the code of our URL: www.mydomain.com/category/product-page?afl=XXXXXX At this moment we have almost 2,000 pages indexed with that code at the end of the URL. So they are all duplicated. My other concern is that I don't know if those affilate links are giving us some link juice or not. I mean, if an original product page has 30 links and the affiliates copies have 15 more... are all those links being counted together by Google? Or are we losing all the juice from the affiliates? Can I fix all this with the canonical tag? Thanks!

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
