Should I worry about duplicate content errors caused by backslashes?
-
Frequently we get red-flagged for duplicate content in the MozPro Crawl Diagnostics for URLs with and without a backslash at the end. For example:
gets flagged as being a duplicate of
I assume that we could rel=canonical this, if needed, but our assumption has been that Google is clever enough to discount this as a genuine crawl error.
Can anyone confirm or deny that?
Thanks.

I would 301 and not rel canoncial. Less chance of error or things getting out of hand. Also, its the correct way to canonicalise urls. The rel canonical tag is for different situations (sorting order etc)

Thanks - well spotted, I was a bit stupid there.
And that does look like an error to me!

I agree with Alex's idea, but not the particular example.
www.mysite.com/Example and www.mysite/example are two different URLs.
You can freely capitalize any letter in the domain name and it makes no difference at all and will always return the same page as per ICANN rules which all major browsers and servers follow.
@Mackenzie, I suggest setting a rule to redirect one version of your URL to the other (with or without a slash). Notice in this moz Q&A the URL does not end in a slash. If you add a slash the site will redirect the URL. What's strange to me is rather then redirecting the URL to the version of the URL without the slash the browser is redirected to the Q&A home page. My guess is that is an error or someone got lazy, but I am typing this reply in the small hope there is a valid reason I am missing and someone will educate me

It is considered as two different addresses, as is www.example.com and www.Example.com. You should add the canonical tag and find out how to specify your preferred version on your server too.

404 error for unknown URL that Moz is finding in our blog
I'm receiving 404 errors on my site crawl for messinastaffing.com. They seem to be generating only from our blog posts which sit on Hubspot. I've searched high and low and can't identify why our site URL is being added at the end - I've tried every link in our blog and cannot repeat the error the crawl is finding. For instance: Referer is: http://blog.messinastaffing.com/take-charge-career-story-compelling-cover-letter/ 404 error is: http://blog.messinastaffing.com/take-charge-career-story-compelling-cover-letter/www.messinastaffing.com I agree that the 404 error URL doesn't exist but I can't identify where Moz is finding it. I have approximately 75 of these errors - one for every blog on our site. Beth Morley Vice President, Operations Messina Group Staffing Solutions

Duplicate URLs
A campaign that I ran said that my client's site had some 47,000+ duplicate pages and titles. I was wondering how I can possibly set that many 301 redirects, but a Moz help engineer said it has a lot to do with session IDs. See this set of duplicate URLs: http://www.lumberliquidators.com/ll/c/engineered-hardwood-flooring (clearly the main URL for the page)

http://www.lumberliquidators.com/ll/c/engineered-hardwood-flooring?PIPELINE_SESSION_ID=0ac071ed0ad4af292684b0746931158f To a crawler, that looks like 4 different pages, when it's clear that they're actually all different URLs for the same page. I was wondering if some of you, maybe with experience in site architecture, would have insight into how to address this issue? Thanks Alan0 -
Videos on duplicate content editing
Hi, I am looking for good videos with visual examples on how to edit duplicate content issues. I am editing a law firms website, and for the most part the duplicate issues seem to show up in tag URL's on the blog. I feel like I have maybe half of the picture figured out, but I am not sure how or where to make changes. I have gone through the crawl diagnostic issues and a few articles, but I know I am a visual learner. Therefore a video might be helpful. Does anyone have any suggestions on where to get started? Thanks.

Duplicate Page Content, Indexing and Rel Canonical Just DOUBLED! Need Advice to Fix
Last Friday (Penguin 5/2.1) my website shot way off the grid and I noticed in my MOZ PRO Campaign dashboard that all of the following just doubled in numbers on my website: duplicate page content, Google indexing, and rel canonicals. I also noticed that some of my pages, images, tags and categories now added a /page/2/ or a -2. I just changed noindex for tags, but indexing for media, pages, posts, and categories. I'm currently using All In One SEO for a plugin. Any advice would be much appreciated as I'm stuck on the issue. relconical.png Duplicate-Page-Content.png [Duplicate Content II](Duplicate Content II) index1.png

Weird 404 Errors
Hi All, Although my Moz error scans have been pretty clean for a while, a law firm site I manage recently cropped up with 80+ 404 errors since the last scan. I'm a little baffled as the url it shows being returned looks like this: http://www.yoursite.com/ http://www.yoursite.com/resource.html For some reason it seems to be initiating a query to call the root domain twice before the actual resource. I installed ModX Revolution 2.2.6-PL on the site in question, and am hoping a canonical plugin I just started using will take care of these. Has this happened to anyone else? What did you do to solve the issue? Thanks for your time and any tips!

How does SEOmoz pull its duplicate page title and content information?
I ask because I am getting errors based on URLs that do not even exist on our site. For example: http://www.robots.com/applications/abb/panasonic/robots this URL does not even exist for our site, but somehow it is listed in the error section of page title duplication tool. http://www.robots.com/applications/ exists, but there is no place to get to an ABB or a Panasonic robot from this page, not to mention an ABB/Panasonic (which for sure does not exist). ?? We have quite a few of these out there and just wondering how to find out where the link is coming from. When we checked our URLs through Integrity, links like the one listed above (which we had 29 of them listed) that do not show up. Thoughts? Thanks! Janelle

How do I find the corresponding duplicate content pages from my SEOmoz report?
Once I have run my report and the duplicate content pages come up, is there a way to find out which pages have the duplicate content on them? I have one URL but where can I find the duplicate content that corresponds to it? Thanks Barry
