    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

                  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 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!

                  Hi All, Screaming frog has identified that we have a few H2 tags on our pages , although we only have 1 H1 tag. We have numerous H3,H4's etc. I am wondering, is it good SEO to have only 1 H2 tag like with H1 tag or can you have more ? thanks Peter

                  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

                  Is a 301 Redirect and a Canonical Tag on Uppercase to Lowercase Pages Correct?

                  We have a medium size site that lost more than 50% of its traffic in July 2013 just before the Panda rollout. After working with a SEO agency, we were advised to clean up various items, one of them being that the 10k+ urls were all mixed case (i.e. www.example.com/Blue-Widget). A 301 redirect was set up thereafter forcing all these urls to go to a lowercase version (i.e. www.example.com/blue-widget). In addition, there was a canonical tag placed on all of these pages in case any parameters or other characters were incorporated into a url. I thought this was a good set up, but when running a SEO audit through a third party tool, it shows me the massive amount of 301 redirects. And, now I wonder if there should only be a canonical without the redirect or if its okay to have tens of thousands 301 redirects on the site. We have not recovered yet from the traffic loss yet and we are wondering if its really more of a technical problem than a Google penalty. Guidance and advise from those experienced in the industry is appreciated.

                  Duplicate Title tags even with rel=canonical

                  Hello, We were having duplicate content in our blog (a replica of each post automatically was done by the CMS), until we recently implemented a rel=canonical tag to all the duplicate posts (some 5 weeks ago). So far, no duplicate content were been found, but we are still getting duplicate title tags, though the rel=canonical is present. Any idea why is this the case and what can we do to solve it? Thanks in advance for your help. Tej Luchmun

                  Partial duplicate content and canonical tags

                  Hi - I am rebuilding a consumer website, and each product page will contain a unique product image, and a sentence or two about the product (and we tend to use a lot of the same words in different ways across products). I'd like to have a tabbed area below the product info that talks about the overall product line, and this content would be duplicate across all the product pages (a "Why use our products" type of thing). I'd have this duplicate content also living on its own URL's so they can be found alone in the SERP's. Question is, do I need to add the canonical tag to this page, since there's partial duplicate content on the product pages? And if I did that, would my product pages go un-indexed?? I understand how to handle completely duplicated content, it's the partial duplicate that I'm having difficulty figuring out.
