301 redirect or rel=canonical
-
On my site, which I created with Joomla, there seems to be a lot of duplicated pages. I was wondering which would be better, 301 redirect or rel=canonical.
On SeoMoz Pro "help" they suggest only the rel=canonical and dont mention 301 redirect. However, ive read many other say that 301 redirect should be the number one option.
Also, does 301 redirect help solve the crawling errors, in other words, does it get rid of the errors of "duplicate page content?"
Ive read that re-=canonical does not right?
Thanks!

No worries Kyu! Just a funny thing about the internet
Sounds like you are doing some great digging today and are being smart about it. I hope it resolves your issues.
Thanks for being thoughtful.

Hi Owen,
The first thumbs down was not me. I thought maybe that I did it on accident so I pushed it again thinking it would negate it, but it added another thumbs down. So Im pretty sure the first one was not me....unless ur allowed to thumbs down twice....
I will try to find a way to undo the thumbs down i did on accident.
Sorry about that and I definitely do appreciate your willingness to help. I am not sure who gave u the thumbs down
Edit: I replaced the thumbs down with a thumbs up
-
Interesting that someone would take the time to thumbs down my post.
That kind of behavior definitely gives me less desire to help people out.

301 redirects basically tell browsers (and search engines) - "Hey this page no longer exists at this URL it is now located here" statistically, you also lose 1-10% of link juice when you 301 redirect a page, and, for duplicate content issues, should be avoided unless it's absolutely necessary.
The rel=canonical tag, however, is a way to tell search engines the preferred version of a given URL. The good thing about this is that you don't lose link juice, and generally it is the least intrusive way to implement a fix to duplicate content issues.
If you were to implement a 301 redirect, you'd have to consider that all of these URLs are different (duplicate content wise) and would need a redirect implemented to a single url:
http://domain.com/sample-page/
http://domain.com/Sample-Page/
etc...etc...etc...
You can see that it can get tedius. By setting will get you the desired results much easier, than implementing tons of 301s.
Hope this helps

Thanks for that!
Do you know if SEOmoz crawlers can pick up redirects?
In other words, will errors still come up when the SEOMOZ crawls?

Canonical tends to be the easiest/quickest method to address these issues. The main difference is that with a 301 the user and the search engine experience the same thing. Whereas with a canonical a user could still access the duplicate page - which in some cases might not be the best user experience. Also, Bing does not follow the directive of a canonical tag.
Here is a good background from Google:

Case Sensitive URLs, Duplicate Content & Link Rel Canonical
I have a site where URLs are case sensitive. In some cases the lowercase URL is being indexed and in others the mixed case URL is being indexed. This is leading to duplicate content issues on the site. The site is using link rel canonical to specify a preferred URL in some cases however there is no consistency whether the URLs are lowercase or mixed case. On some pages the link rel canonical tag points to the lowercase URL, on others it points to the mixed case URL. Ideally I'd like to update all link rel canonical tags and internal links throughout the site to use the lowercase URL however I'm apprehensive! My question is as follows: If I where to specify the lowercase URL across the site in addition to updating internal links to use lowercase URLs, could this have a negative impact where the mixed case URL is the one currently indexed? Hope this makes sense! Dave

Order and multiple match when 301 redirect ?
Hi, I'm migrating a single domain to a multiple domain for each language, using apache redirections: Redirect 301 /partners http://www.itris-automation.com/
Intermediate & Advanced SEO | | 2MSens
Redirect 301 /partner-si http://www.itris-automation.com/system-integrators-partners
Redirect 301 /partner-institute http://www.itris-automation.com/institutional-partners
Redirect 301 /fr/ http://www.itris-automation.fr/
Redirect 301 /fr/support http://www.itris-automation.fr/support
Redirect 301 /privacy?lang=fr http://www.itris-automation.fr/politique-de-confidentialite Redirect 301 /de/plc-converter http://www.itris-automation.de/plc-converter
Redirect 301 /de/services http://www.itris-automation.de/
Redirect 301 /de/plc-quality http://www.itris-automation.de/sps-qualitat .... However it doesn't work properly: For example automationsquare.com/privacy?lang=fr redirect to http://www.itris-automation.com/privacy instead of http://www.itris-automation.fr/politique-de-confidentialite Does the order of the redirect has an influence? Am I missing something? I've seen that the command [L] can be useful to avoid mismatch? Thanks, Best, Benoit.0 -
301 and Canonical - is using both counterproductive
A site lost a great deal of traffic in July, which appears to be from an algorithmic penalty, and hasn't recovered yet. It appears several updates were made to their system just before the drop in organic results. One of the issues noticed was that both uppercase and lowercase urls existed. Example urls are: www.domain.com/product123
Intermediate & Advanced SEO | | ABK717
www.domain.com/Product123 To clean this up, a 301 redirect was implemented a few months ago. Another issue found was that many product related urls had a parameter added to the url for a tracking purpose. To clean this up, the tracking parameters were removed from the system and a canonical tag was implemented as these pages were also found in Google's index. The tag forced a page such as www.domain.com/product123?ref=topnav to be picked up as www.domain.com/product123. So now, there is a 301 to address the upper and lowercase urls and a canonical tag to address the parameters from creating more unnecessary urls. A few questions here: -Is this redunant and can cause confusion to the serps to have both a canonical and 301 redirect on the same page? -Both the 301 and canonical tag were implemented several months ago, yet Google's index is still showing them. Do these have to be manually removed with GWT individually since they are not in a subfolder or directory? Looking forward to your opinions.0 -
Is a 301 to a 301 ok?
I have a site that has a lot of url differences. Due to coding we sometimes have to 301 to a page that is 301'd to another. Is there any danger in doing this?

301 redirects and Blogger - moving blog
Is there any way to add 301 redirects to individual posts on a blogger-hosted blog? We're getting ready to finally move our blog off of Blogger and onto our own webserver. We're probably going to use BlogEngine.net to run it. right now the blog is located at blog.MySite.com. We're probably going to move it to MySite.com/Blog. We don't have any really popular posts and we only really get ~10 visits a day on about 70 posts. Just trying to figure out the best way to handle this without inadvertently shooting myself in the foot.

Embed Same Video On Multiple Pages or 301 Redirect Into 1?
I have 3 pages that rank VERY well for related terms such as: -How to get widgets -How to become a widget -Getting widgets -etc. I am incorporating a video on the topic and rewriting much of the content on the site. I am wondering if it is wise to 301 redirect all 3 pages to 1 page that has the new/better video content or if I should leave the old content that is ranking well and embed the video on the top of each. The anal retentive side of me wants a nice new site structure and 1 powerful page. However, if the 3 pages are currently ranking (sometimes 2 pages in the same top 10 results), should I mess with what is working? Ultimately my goal is to increase the avg time on site as these 3 pages are top traffic pages for the site. However, they do not convert at all, as they are for a product we don't offer. Thoughts?

Effect of 301 redirect to a relative url to homepage?
One of our new clients recently encountered a site-wide ranking drop for many keywords and I'm pretty confident regarding their link profile as to being 98% legit. Background: 1. Client full site is https, and all http pages are 301 redirected to their https counterpart 2. Client has ~50 links partners (all legitimate sites + schools etc) links to client with urls such as www.example.com/portal/123.aspx that redirects to www.example.com. 3. Client homepage 301 redirects from www.example.com to www.example.com/default.aspx and then 301 redirects to the relative url "/Home.aspx". 4. Client launched some testing with Google website optimizer tool. ~1-2 months ago. Symptoms: 1. Rankings dropped for basically many/all 30-40+ keywords by ~15 positions 2. Seomoz reports close to a double of existing pages + (600+) duplicate content in the same date range. Webmasters only report 80 duplicate titles though. 3. Domain authority by seomoz reduced a bit + backlinks recorded by seomoz to the website nearly halved in the past 2 months. I'm not sure if I narrowed this towards the right direction, and it isn't clear when the relative url 301 redirect was implemented: 1. The 301 redirect to the relative page (www.example.com/default.aspx to "/home.aspx") is accounting for the loss of links recorded by seomoz. 2. The ~50 links the client currently use (www.example.com/portal.123.aspx 301 redirecting to www.example.com, also relative) as a tracking tool is being considered 301 redirect abuse. 3. Maybe something went wrong with the usage of google optimizer tool for SEO purposes? Visitor traffic to each of the tested pages looked fine. I would greatly appreciate any advice/insights on what I might be missing in terms of direction / factors. Thanks! Alex

Rel canonical issues on wordpress posts
