Rel canonical Issue
-
I have a huge rel canonical issue showing up on my website, and I'm not sure that I fully understand why. To my knowledge, this is something that comes about when alternate urls are used to link to the same page. However, this is not a technique that I've used with my website, yet it's still raising a flag on just about every page.
Can anyone enlighten me on what's causing this?
Thanks

We tag near-duplicates in the system, so I think you've got a combination of factors:
(1) There's only one post on some of the tag pages.
(2) The posts don't have a lot of text, so the "snippet" duplicates about 1/3 to 1/2 of it.
(3) The navigation/code is pretty heavy, compared to content.
Once those tag pages have more posts/snippets, I don't think you'll see problems. Be careful, as you grow, with how many tags you create. Tag searches can start to look a bit thin, and you may want to exclude them (or some of them) from the search index down the road. For now, I think you're probably ok. Once those tags have 3-4 snippets on them, the pages should look a lot better.

I'm still learning, so it's a little hard for me to explain. But basically, I have 95 duplicate content warnings. What's coming up is the tag linked to the post and the actual post itself. Which in itself seems like a problem, plus I thought maybe that's related to the rel can. notices.

You mean because there's only one entry in that tag result? It's not necessarily a problem, but if you spin out a lot of those tag pages, that content can look a little thin. It's a balancing act. As the site grows, you may want to consider whether or not to let every tag be indexed. Usually, it's only a problem on large sites, though.

Hi,
Thanks everyone for the great insight. I think I may have found another problem that's related to this though. I also have a lot of duplicate content warnings, which is also odd. Here's what I found.
Seems like I have tag urls linking to content - for instance:
is this considered being linked to the actual post/perma?
autodebut.com/2012/techart-2012-porsche-911-revealed-at-geneva-motor-show/#more-6382
Could that be causing the problem?

donford is correct, I believe the notive is to let you know where the canonicals are as they can be dangerous if you put them in wrong.

Hi Dorian,
To my knowledge the Rel Warning from SeoMoz doesn't mean something is wrong, rather that the tag was detected.
I believe this is because if you can, you should properly redirect 301 to the correct URL instead of saying hey don't index this as what you see but what I say (which is what rel canonical does). However, there are cases with dynamic URL's this isn't always avoidable so the tag does server a purpose.

Having a quick look on your website, the use of canonical tag looks fine. What exactly is the problem you are having ?
-
SEOmoz pro just finished crawling my website and it's coming up with 250 rel canonical warnings.
Here's one example:
"
<dt>Description</dt>
<dt>Using rel=canonical suggests to search engines which URL should be seen as canonical."</dt>
<dt>That's all it's saying. I also have metarobots set to noodp,noydir - but I'm sure that doesn't make any difference with this.</dt>

On site issues after Magento 2 launch
We did a new site launch on Feb 7th this year - www.vesternet.com It changed from Magento 1 to Magento 2. We had some launch issues around SEO but now we've solved most every crawler issue in Moz reporting - according to Moz we're in better shape on-site than ever. But our organic search is just dropping daily - we expected a drop after launch then back to normal, but over 2 months on something just isn't right. A good example, on Google UK for keyword 'home automation' we've always been about position 10, but now we're out the top 50... Forget about off site for now - what's wrong with our site itself to have caused this? Can anyone help with insights please as this is killing our sales

Will Multiple 301's to the Same URL Cause Issues?
Hey Everyone, We have a client (I don't have permission to disclose) that has just attempted to create better URL's for their site, per our direction. In the process, their website platform kind of took over their renaming attempts and instead of creating the clean, short, descriptive URLs we all wanted, they got convoluted, longer URLs. This all happened within the past 3 or 4 days. So, they went out and got an add-on that's going to help them create better URL's. In the meantime, they now have the original page/URL plus two new ones for a total of three. No 301's have been setup yet. When they create the new and (hopefully) improved URL tomorrow, will it hurt their rankings to have three pages redirected to the new one? Is a 301 redirect the right method for this issue or should they do something different? Thanks in advance, Kirk

How do I fix my portfolio causing duplicate content issues?
Hi, Im new to this whole duplicate content issue. I have a website, fatcatpaperie.com that I use the portofolio feature in Wordpress as my gallery for all my wedding invitations. I have a ton of duplicate content issues from this. I don't understand at all how to fix this. I'd appreciate any help! Below is an example of one duplicate content issue. They have slightly different names, different urls, different images and all have no text. But are coming up as duplicates. Would it be as easy as putting a different metadescription for each??

Using Canonical & INDEX, FOLLOW meta tag
I am sort of new to this, and working with an overseas development team on an eCommerce site. I am curious if the Canonical tag will supersede the tag, or if it is best to remove this tag entirely for duplicate product pages?

Google is indexing urls with parameters despite canonical
Hello Moz, Google is indexing lots of urls despite the canonical in my site. Those urls are linked all over the site with parameters like ?, and looks like Google is indexing them despite de canonical. Is Google deciding to index those urls because they are linked all over the site? The canonical tag is well implemented.

Can someone help with Canonical?
I have a wordpress site that On-Page Grader is saying I don't have Canonical done correctly. Here is the comment. Appropriate Use of Rel Canonical If the canonical tag is pointing to a different URL, engines will not count this page as the reference resource and thus, it won't have an opportunity to rank. Make sure you're targeting the right page (if this isn't it, you can reset the target above) and then change the canonical tag to reference that URL. Recommendation: We check to make sure that IF you use canonical URL tags, it points to the right page. If the canonical tag points to a different URL, engines will not count this page as the reference resource and thus, it won't have an opportunity to rank. If you've not made this page the rel=canonical target, change the reference to this URL. NOTE: For pages not employing canonical URL tags, this factor does not apply. I have quite a few sites and have never had an issue with this. Can anyone help? I tried installing a plugin but that seems to have made it worse. This is the front page of the site btw.

301 to Intermediate Page then Rel=Canonical from Intermediate to target page
Hi I'm working on an eCommerce site and don't have direct access to the CMS. I had requested developers to provide me a facilty to 301 via htaccess however this is working slight differently. I need guidance from experts whether it's okay or not: Old Page: example.com/old Target New Page: example.com/new After Implementing the redirect, It redirects to an intermediate page or in other words, The same target URL with a question mark added: example.com/new? (notice the question mark in the new URL) This intermediate page has a canonical tag for the exact target URL. So, if I 301 redirect example.com/old to example.com/new? (Intermediate page) and If the intermediate page example.com/new? has a canonical tag for the exact target URL (example.com/new), Will I be able to pass the link juice and authority of old page to the new page?
