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.

Home Page Title - Google Overriding my Title Tag
Hi, We have noticed our home page title tag has now been replaced by our brand name (by Google I'm assuming). We have also noted that the page is dropping off SERPS for our main keywords, I suspect they are related but ofc I cant be sure. I know the recent Google update has impacted titles but I wasn't sure if it would apply here. Has anyone any advice on this and/or having the same issue? We normally rank well for grass seed (UK search) https://thegrasspeople.com/ I also noticed some strange mark up in our source code which seems to have been left behind by Sketch - we are getting this removed. <title>Combined Shape</title> <desc>Created with Sketch.</desc> Chris

Breaking up a site into multiple sites
Hi, I am working on plan to divide up mid-number DA website into multiple sites. So the current site's content will be divided up among these new sites. We can't share anything going forward because each site will be independent. The current homepage will change to just link out to the new sites and have minimal content. I am thinking the websites will take a hit in rankings but I don't know how much and how long the drop will last. I know if you redirect an entire domain to a new domain the impact is negligible but in this case I'm only redirecting parts of a site to a new domain. Say we rank #1 for "blue widget" on the current site. That page is going to be redirected to new site and new domain. How much of a drop can we expect? How hard will it be to rank for other new keywords say "purple widget" that we don't have now? How much link juice can i expect to pass from current website to new websites? Thank you in advance.

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!

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

Proper 301 in Place but Old Site Still Indexed In Google
So i have stumbled across an interesting issue with a new SEO client. They just recently launched a new website and implemented a proper 301 redirect strategy at the page level for the new website domain. What is interesting is that the new website is now indexed in Google BUT the old website domain is also still indexed in Google? I even checked the Google Cached date and it shows the new website with a cache date of today. The redirect strategy has been in place for about 30 days. Any thoughts or suggestions on how to get the old domain un-indexed in Google and get all authority passed to the new website?

Should you use a canonical tag on translated content in a multi-language country?
A customer of ours has a website in Belgium. There two main languages in Belgium: Dutch and French.
Intermediate & Advanced SEO | | Zanox
At first there was only a Dutch version with a .be extension. Right now they are implementing the French Belgium version on the URL website.be/fr. All of the content and comments will be translated. Also the URL’s will change from Dutch to French, so you've got two URL’s with the same content but in another language. Question: Should you use a canonical tag on translated content in a multi-language country? I think Google will understand this is just for the usability for a Multilanguage country. What do you guys think???0 -
Any penalty for having rel=canonical tags on every page?
For some reason every webpage of our website (www.nathosp.com) has a rel=canonical tag. I'm not sure why the previous SEO manager did this, but we don't have any duplicate content that would require a canonical tag. Should I remove these tags? And if so, what's the advantage - or disadvantage of leaving them in place? Thank you in advance for your help. -Josh Fulfer
