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.

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.

Fast/Easy Way to Implement Canonical tags in Bulk in Magento CMS?
Hello Amazing SEO Community! Quick Q for a client with a TON of duplicate content. (yikes!) My client is currently undertaking a large SEO project around canonical tagging for their thousands of duplicate pages. Currently, one product sits on multiple URLs and they are being indexed as different pages (with the same content). The issue is found across all products and other pages, and across their international sites as well. One core challenge they face now is lack of time/resources from their developer side. The solution we see to the duplicate content is to manually add a canonical tag to each of our tens of thousands of pages. Their content management system is Magento. Has anyone ever tackled canonicalization for a large site that uses Magento? Any more efficient solutions to manual tagging is ideal. Thanks in advance for your input. -Bonnie

Moving to a new site while keeping old site live
For reasons I won't get into here, I need to move most of my site to a new domain (DOMAIN B) while keeping every single current detail on the old domain (DOMAIN A) as it is. Meaning, there will be 2 live websites that have mostly the same content, but I want the content to appear to search engines as though it now belongs to DOMAIN B. Weird situation. I know. I've run around in circles trying to figure out the best course of action. What do you think is the best way of going about this? Do I simply point DOMAIN A's canonical tags to the copied content on DOMAIN B and call it good? Should I ask sites that link to DOMAIN A to change their links to DOMAIN B, or start fresh and cut my losses? Should I still file a change of address with GWT, even though I'm not going to 301 redirect anything?

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.

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 -
Malicious site pointed A-Record to my IP, Google Indexed
Hello All, I launched my site on May 1 and as it turns out, another domain was pointing it's A-Record to my IP. This site is coming up as malicious, but worst of all, it's ranking on keywords for my business objectives with my content and metadata, therefore I'm losing traffic. I've had the domain host remove the incorrect A-Record and I've submitted numerous malware reports to Google, and attempted to request removal of this site from the index. I've resubmitted my sitemap, but it seems as though this offending domain is still being indexed more thoroughly than my legitimate domain. Can anyone offer any advice? Anything would be greatly appreciated! Best regards, Doug

Should I prevent Google from indexing blog tag and category pages?
I am working on a website that has a regularly updated Wordpress blog and am unsure whether or not the category and tag pages should be indexable. The blog posts are often outranked by the tag and category pages and they are ultimately leaving me with a duplicate content issue. With this in mind, I assumed that the best thing to do would be to remove the tag and category pages from the index, but after speaking to someone else about the issue, I am no longer sure. I have tried researching online, but there isn't anything that provided any further information. Please can anyone with any experience of dealing with issues like this or with any knowledge of the topic help me to resolve this annoying issue. Any input will be greatly appreciated. Thanks Paul
