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.

Does Google ignore content styled with 'display:none'?
Do you know if an H1 within a div that has a 'display: none' style applied will still be crawled and evaluated by Google? We have that situation on this page on line 136: view-source:https://www.junk-king.com/services/items-we-take/foreclosure-cleanouts Of course we also have an H1 up at the top of the page and are concerned that the second one will cause interference with our SEO efforts. I've seen conflicting and inconclusive information on line - not sure. Thanks for any help.

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!

Capitalization of first letter of each word in meta description. Catches more attention, but may this lead to google ignoring the meta description then more frequently?
Capitalization of first letter of each word in meta description. Catches more attention, but may this lead to google ignoring the meta description then more frequently? Same for an occasional capitalized FREE in meta description. Anybody had experience with this?

Should I use **tags or h1/h2 tags for article titles on my homepage**
I recently had an seo consultant recommend using tags instead of h1/h2 tags for article titles on the homepage of my news website and category landing pages. I've only seen this done a handful of times on news/editorial websites. For example: http://www.muscleandfitness.com/ Can anyone weigh in on this?

Adding hreflang tags - better on each page, or the site map?
Hello, I am wondering if there seems to be a preference for adding hreflang tags (from this article). My client just changed their site from gTLDs to ccTLDs, and a few sites have taken a pretty big traffic hit. One issue is definitely the amount of redirects to the page, but I am also going to work with the developer to add hreflang tags. My question is - is it better to add them to the header of each page, or the site map, or both, or something else? Any other thoughts are appreciated. Our Australia site, which was at least findable using Australia Google before this relaunch, is not showing up, even when you search the company name directly. Thanks!Lauryn

Will Google View Using Google Translate As Duplicate?
If I have a page in English, which exist on 100 other websites, we have a case where my website has duplicate content. What if I use Google Translate to translate the page from English to Japanese, as the only website doing this translation will my page get credit for producing original content? Or, will Google view my page as duplicate content, because Google can tell it is translated from an original English page, which runs on 100+ different websites, since Google Translate is Google's own software?

Canonical tag - but Title and Description are slightly different
I am building a new SEO site with a "Silo" / Themed architecture. I have a travel website selling hotel reservations. I list a hotel page under a city page - example, www.abc.com/Dallas/Hilton.html Then I use that same property under a segment within the city - example www.abc.com/Dallas/Downtown/Hilton.html, so there are two URLs with the same content Both pages are identical, except I want to customize the Title and Description. I want to customize the title and description to build a consistent theme - for example the /Downtown/Hilton page will have the words "Near Downtown" in the Title and Description, while the primary city Hilton page will not. So I have two questions about this. First, is it okay to use a canonical tag if the Title and Description are slightly different? Everything else is identical. If so, will Google crawl and comprehend the unique Title and Description on the "Downtown" silo? I want Google to see that I have several "supporting" pages to my main landing page(s). I want to present to Google 5 supporting pages in each silo that each has a supporting keyword theme. But I'm not sure if Google will consider content of pages that point to a different page using the canonical tag. Please see this supporting example: http://d.pr/i/aQPv Thanks for your insights. Rob

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?
