      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:

      http://webcache.googleusercontent.com/search?q=cache:zcxT7MRHHREJ:www.microsoftstore.com/store/msusa/en_US/pdp/Surface-Book/productID.325716000%3Fbvstate%3Dpg:8/ct:r+&cd=2&hl=en&ct=clnk&gl=us

      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:

      http://webcache.googleusercontent.com/search?q=cache:k0MBLFcu2PoJ:www.homedepot.com/p/DUROCK-Next-Gen-1-2-in-x-3-ft-x-5-ft-Cement-Board-172965/202263276%23!bvstate%3Dct:r/pg:2/st:p/id:202263276+&cd=1&hl=en&ct=clnk&gl=us

        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.

                http://prntscr.com/aqwnhu

                http://prntscr.com/aqwo4c

                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

                    title tags

                    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

                    Hreflang and canonical tag for new country specific website - different base domain

                    I have a little different situation compared to most other questions which asks for hreflang and canonical tags for country specific version of websites. This is an SEO related question and I was hoping to get some insight on your recommendations. We have an existing Australian website - say - ausnight.com.au now we want to launch a UK version of this website - the domain is - uknight.co.uk please note, we are not only changing from .com.au to .co.uk.... but the base domain name as well changed - from ausnight to uknight as you can understand, the audience for both websites is different. Both websites has most pages same with same contents.... the questions I have is - Should we put canonical tag on the new website pages? If we don't put canon tag on new website pages, what is the impact on the SEO ranking of current website? I believe we need to put hreflang tag on both websites to tell google that we have another language version (en-au vs en-gb) of the same page. Is this correct?

                    Google Is Indexing my 301 Redirects to Other sites

                    Long story but now i have a few links from my site 301 redirecting to youtube videos or eCommerce stores. They carry a considerable amount of traffic that i benefit from so i can't take them down, and that traffic is people from other websites, so basically i have backlinks from places that i don't own, to my redirect urls (Ex. http://example.com/redirect) My problem is that google is indexing them and doesn't let them go, i have tried blocking that url from robots.txt but google is still indexing it uncrawled, i have also tried allowing google to crawl it and adding noindex from robots.txt, i have tried removing it from GWT but it pops back again after a few days. Any ideas? Thanks!

                    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

                    How can I get a list of every url of a site in Google's index?

                    I work on a site that has almost 20,000 urls in its site map. Google WMT claims 28,000 indexed and a search on Google shows 33,000. I'd like to find what the difference is. Is there a way to get an excel sheet with every url Google has indexed for a site? Thanks... Mike

                    Lowercase VS. Uppercase Canonical tags?

                    Hi MOZ, I was hoping that someone could help shed some light on an issue I'm having with URL structure and the canonical tag. The company I work for is a distributor of electrical products and our E-commerce site is structured so that our URL's (specifically, our product detail page URL's) include a portion (the part #) that is all uppercase (e.g: buy/OEL-Worldwide-Industries/AFW-PG-10-10). The issue is that we have just recently included a canonical tag in all of our product detail pages and the programmer that worked on this project has every canonical tag in lowercase instead of uppercase.  Now, in GWT, I'm seeing over 20,000-25,000 "duplicate title tags" or "duplicate descriptions". Is this an issue?  Could this issue be resolved by simply changing the canonical tag to reflect the uppercase URL's?  I'm not too well versed in canonical tags and would love a little insight. Thanks!

                    Rel=canonical tag on original page?

                    Afternoon All,
                    We are using Concrete5 as our CMS system, we are due to change but for the moment we have to play with what we have got. Part of the C5 system allows us to attribute our main page into other categories, via a page alaiser add-on. But what it also does is create several url paths and duplicate pages depending on how many times we take the original page and reference it in other categories. We have tried C5 canonical/SEO add-on's but they all seem to fall short. We have tried to address this issue in the most efficient way possible by using the rel=canonical tag. The only issue is the limitations of our cms system. We add the canonical tag to the original page header and this will automatically place this tag on all the duplicate pages and in turn fix the problem of duplicate content. The only problem is the canonical tag is on the original page as well, but it is referencing itself, effectively creating a tagging circle. Does anyone foresee a problem with the canonical tag being on the original page but in turn referencing itself? What we have done is try to simplify our duplicate content issues. We have over 2500 duplicate page issues because of this aliasing add-on and want to automate the canonical tag addition, rather than go to each individual page and manually add this tag, so the original reference page can remain the original. We have implemented this tag on one page at the moment with 9 duplicate pages/url's and are monitoring, but was curious if people had experienced this before or had any thoughts?

                    Does Google crawl the pages which are generated via the site's search box queries?

                    For example, if I search for an 'x' item in a site's search box and if the site displays a list of results based on the query, would that page be crawled? I am asking this question because this would be a URL that is non existent on the site and hence am confused as to whether Google bots would be able to find it.
