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.

Rel canonical tag from shopify page to wordpress site page
We have pages on our shopify site example - https://shop.example.com/collections/cast-aluminum-plaques/products/cast-aluminum-address-plaque That we want to put a rel canonical tag on to direct to our wordpress site page - https://www.example.com/aluminum-plaques/ We have links form the wordpress page to the shop page, and over time ahve found that google has ranked the shop pages over the wp pages, which we do not want. So we want to put rel canonical tags on the shop pages to say the wp page is the authority. I hope that makes sense, and I would appreciate your feeback and best solution. Thanks! Is that possible?

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?

Merging Two Unrelated Sites into a Third Site
We have a new client interested in possibly merging 2 sites into one under the brand of a new parent company. Here's a breakdown of the scenario..... BrandA.com sells a variety of B2B widget-services via their online store. BrandB.com sells a variety of B2B thing-a-majig products and services (some of them large in size) not sold through an online store. These are sold more consultatively via a sales team. The new parent company, BrandA-B.com is considering combining the two sites under the new brand parent company domain. The Widget-services and Thing-A-Majigs have very little similarity or purchase crossover; so just because you're interested in one doesn't make you a good candidate for the other. We feel pretty confident that we can round-up all the necessary pages and inbound links to do proper transitioning to a new, separate third domain though we're not in agreement that this is the best course of action. Currently the individual brand sites are fairly well known in their industry and each ranks fairly well for a variety of important terms though there is room for improvement and each site has good links with the exception of the new site which has considerably fewer. BrandA.com DA = 73 - 19 years old

BrandB.com DA = 55 - 18 years old
BrandA-B.com DA = 40 - 1 year old Our SEO team members have opinions on what the potential outcome(s) of this would be but are wondering what the community here thinks. Will the combining of the sites cause a dilution of the topics of the two sites and hurt rankings? Will the combining of the domain authority help one set part of the business but hurt the other? What do you think? What would you do?0 -
Can Google penalize your site without sending you a Manual Spam Action?
I had a massive drop in traffic in Mid 2013, and a slow reduction since then. It has sort of leveled off now, but it's not exactly climbing I've never received a manual spam action. The answer to my question seems pretty obvious, now that I write it out... but have you heard of anyone getting penalized, without specifically receiving a warning? Thanks!

Hi All, I have a Rental site and I am bit confused with how best do my H Tags on my homepage I know the H1 is the most important, Then H2 Tags and so on.. and that these tags should really be titles for content.

I am attached a made up screenshot of what I propose for my homepage if someone could please give it a quick look , it would be very much appreciated. I have looked at what some competitors do a lot of them don't seem to have h2's etc but I know it's an important factor for rankings etc. Many thanks Pete dJSFQwI

Why is google truncating my title tag?
We are trying to figure out why the search result for the term "au pair" is not matching our designated title tag or anything on our page. If you search "au pair", please see the result for the domain interexchange.org. We do not see this problem with other search terms.

Why is my m-dot site outranking my main site in SERPs?
My client has a WP site and a Duda mobile site that we inherited. For some reason their m-dot site is ranking on P1 of Google for their top KWs instead of the main site which is much more robust. The main site might rank beyond page 5 when the generic home page for their m-dot site appears on P1. Does anyone have any idea why this might be happening?

Site #2 beats site #1 in every aspect?
Hey guys, loving SEOMoz so far and will definitely continue my subscription after the free trial. I have a question however, which I am really confused about. When researching my primary keyword, I have found that the second ranked site beats the top site in every single aspect, apart from domain age, which is almost 6 years for the top one and 6 months for the second. When I say every single aspect, I mean everything. More authority for the page and domain, more links, more anchor text links, more authoritive links, more social signals, more relevant links, better domain (although second ranked site is a .net), better MozRank, better MozTrust etc.... I have noticed though, that in the UK SERPs, those sites are switched, so #2 is actually #1. Could it be that the US SERPs just haven't updated yet, or am I missing something completely different.
