Rel="canonical" tag is implemented in my product pages, but still getting canoncal error for products in Moz. What is the problem? me or MOZ?
-
I have included the rel="canonical" tag in all my product pages, but still getting canonical error in MOZ reports for more than 6 month ! I would like to know if my code is wrong or the MOZ report system is not working properly.
Here is an example of my canonical code in line 84
rel="canonical" href="http://www.doornmore.com/slab-single-door-80-fiberglass-courtlandt-1-panel-arch-lite-glass.html" />
Thanks

Peter,
Thank you for responding to my question. I actually noticed that the pages that Moz is considering as duplicate content, is not a duplicate. However they are very similiar with slietly difference. I do not how to tell the crawlers not to index as a duplication.
Thank you

Hi there Shayann,
Thanks for writing in! I would take a look at where these pages' canonicals are pointing. if their canonical tags point to different URLs, then they can be consider duplicates. For example, DUPLICATE1 is considered a duplicate of DUPLICATE2 because the canonical tag for the first page is CANON1 while the canonical for the second URL is CANON2.
Since the canonical tags point to different pages it is assumed that CANON1 and CANON2 are likely to be duplicates themselves.
Here is how our system interprets duplicate content vs. rel canonical:
Assuming A, B, C, and D are all duplicates,
If A references B as the canonical, then they are not considered duplicates
If A and B both reference C as canonical, A and B are not considered duplicates of each other
If A references C as a canonical, A and B are considered duplicated
If A references C as canonical, B references D, then A and B are considered duplicates
The examples you've provided actually fall into the fourth example I've listed above.For more information on using canonical tags, check out this great post by our very own Dr. Pete:

Shayann, you should check which are the 2 Other URLs that create this issue, to check if they implement different rel=canonical tags.

Hey Shayann,
What errors related to rel=canonical do you get in your Moz report?
Inside the Crawl Diagnostics Summary, the rel=canonical tag is listed inside the Notices block. That means it's just a count of how many pages have this tag implemented, and doesn't imply there are any errors with it, but simply that the tag is present on your pages.
Hope this helps!

Pages with Temporary Redirects on pages that don't exist!
Hi There Another obvious question to some I hope. I ran my first report using the Moz crawler and I have a bunch of pages with temporary redirects as a medium level issue showing up. Trouble is the pages don't exist so they are being redirected to my custom 404 page. So for example I have a URL in the report being called up from lord only knows where!: www.domain.com/pdf/home.aspx This doesn't exist, I have only 1 home.aspx page and it's in the root directory! but it is giving a temp redirect to my 404 page as I would expect but that then leads to a MOZ error as outlined. So basically you could randomize any url up and it would give this error so I am trying to work out how I deal with it before Google starts to notice or before a competitor starts to throw all kinds at my site generating these errors. Any steering on this would be much appreciated!

MOZ Not Picking Up Facebook "Likes"
For some reason MOZ is not registering the number of Facebook likes my corporate Facebook page has. Over 700 likes have accumulated, yet MOZ is showing zero. It is strange because MOZ has picked up three Facebook "shares". Does anyone have an idea how this issue can be corrected? Thanks,

Do I need to set the country in Webmaster Tools even if I am set to apply the hreflang tag to our different country pages?
We are global brand that will be migrating to a new platform in the next few months. As such, this will allow us to fix our current SEO issues. We are planning on using geo-targeted subfolders instead of country code top level domains primarily because of resource limitations. My question is - do I need to set the country in Webmaster Tools even though I am already going to tell Google that certain pages are targeted towards a specific country?

Rel Canonical Question
Hi all. I think I'm a bit confused. When I check my crawl diagnostics its listing lots of warnings under the heading rel-canonical. I am not sure why, since virtually all my pages have the link rel="<a class="attribute-value">canonical</a>" tag. I use it because there are a lot of possible extensions that can appear on the pages as it is an eCommerce site. Why would seomoz list this as a warning? Thanks Ken

How can I prevent errors of duplicate page content generated by my tags from my wordpress on-site blog platform?
When I add meta data and a canonical reference to my blog tags for my on-site blog which works using a wordpress.org template, Roger generates errors of duplicate content. How can I avoid this problem? I want to use up to 5 tags per post, with the same canonical reference and each campaign scan generates errors/warnings for me!

Not all pages are being crawled
I am set up on the PRO plan, I was under the impression that it would crawl up to 10,000 pages. My site has just over 200 pages, but whenever I am crawled it only crawls 121 pages. Is this normal? It's hard to know how reliable my data is because a significant amount of pages are missing.
