      I have setup my website to use canonical urls on each page to point to the page i wish Google to refer to.

      At the moment, my non-www domain name is not redirected to www domain. Is this required if i have setup the canonical urls?

      This is the tag i have on my index.php page

      rel="canonical" href="http://www.mydomain.com.au" />

      If i browse to http://mydomain.com.au should the link juice pass to http://www.armourbackups.com.au?

      Will this solve duplicate content problems?

      Thanks

        Dan is correct and the biggest reason to redirect the www to non www or non www to www is that the chance will always exist that they will be seen as two sites and by virtue of that you will split the value of the site. We see it every day when we take on new clients.  While the DA is the same on both, the PA for a home page or important other ranking page is different. One I just finished sending a proposal on has a DA of 23 for the site. The www version home page has a PA of 32 while the non www version has a PA of 21. There are four links on the non www that do not exist on the www.

        So, your call, Dan is right.

        Best

          Hi

          A canonical is kind of like a last resort if a redirect can't be used - and best applies to handling campaign URL parameters and session IDs etc. You really ought to redirect all possible variations of the homepage to one singular URL no matter what. This way people will only link to one version of it (or at least be more likely to).

          -Dan

            Reusing an already 301 redirected URL for a very important keyword

            301 redirect 301 redirects

            I have a question about reusing an already 301 redirected URL Till now I never reused an URLs that has been already redirected with a 301 redirect. However, I just started working on a website where in past they created a lot of 301 redirects without thinking about the future, and now certain URLs, that are currently redirected with a 301, would be very useful (exact match) and needed (for some of the most important keywords for this specific business), to maintain an optimal, homogeneous and "beautiful" URL structure. Has any of you ever reused a URL that was previously redirected with a 301 redirect? If yes what are your experiences with it? Can content on the reused URL (that was previously 301 redirected and than the redirect removed) normally rank if the page is reestablished and the redirect is removed (and you do great content, on page, internal linking, backlinking, .... ) or is such an URL risky / not recommended / "burned" forever and not recommended to be reused again... especially for very important keywords since it present the exact match ?! Thank you very much for all your help! Regards

            How to redirect 302 status to 301 status code using wordpress

            I just ran the link opportunity option within site explorer and it shows that 31 pages are currently in a 302 status.  Should I try to convert the 302's to 301's?  And what is the easiest way to do this? I see several wordpress plugins that claim to do 301 redirects but I don't know which to choose. Any help would be greatly appreciated!

            Using the Google Remove URL Tool to remove https pages

            I have found a way to get a list of 'some' of my 180,000+ garbage URLs now, and I'm going through the tedious task of using the URL removal tool to put them in one at a time. Between that and my robots.txt file and the URL Parameters, I'm hoping to see some change each week. I have noticed when I put URL's starting with https:// in to the removal tool, it adds the http:// main URL at the front. For example, I add to the removal tool:- https://www.mydomain.com/blah.html?search_garbage_url_addition On the confirmation page, the URL actually shows as:- http://www.mydomain.com/https://www.mydomain.com/blah.html?search_garbage_url_addition I don't want to accidentally remove my main URL or cause problems. Is this the right way this should look? AND PART 2 OF MY QUESTION If you see the search description in Google for a page you want removed that says the following in the SERP results, should I still go to the trouble of putting in the removal request? www.domain.com/url.html?xsearch_... A description for this result is not available because of this site's robots.txt – learn more.

            Rel=Canonical, WWW vs non WWW and SEO

            Okay so I'm a bit of a loss here.  For what ever reason just about every single Wordpress site I has will turn www.mysite.com into mysite.com in the browser bar.  I assume this is the rel=canonical tag at work, there are no 301s on my site. When I use the Open Site Explorer and type in www.mysite.com it shows a domain authority of around 40 and a few hundred backlinks... and then I get the message. Oh Hey! It looks like that URL redirects to XXXXXX. Would you like to see data for <a class="clickable redirects">that URL instead</a>? So if I click to see this data instead I have less than half of that domain authority and about 2 backlinks. *** Does this make a difference SEO wise?  Should my non WWW be redirecting to my WWW instead because that's where the domain authority and backlinks are? Why am I getting two different domain authority and backlink counts if they are essentially the same?  Or am I wrong and all that link juice and authority passes just the same?

            Drupal URL Aliases vs 301 Redirects + Do URL Aliases create duplicates?

            Hi all! I have just begun work on a Drupal site which heavily uses the URL Aliases feature. I fear that it is creating duplicate links. For example:: we have http://www.URL.com/index.php and http://www.URL.com/ In addition we are about to switch a lot of links and want to keep the search engine benefit. Am I right in thinking URL aliases change the URL, while leaving the old URL live and without creating search engine friendly redirects such as 301s? Thanks for any help! Christian

            URL query strings and canonical tag

            Hi, I have recently been getting my comparison website redesigned and developed onto wordpress and the site is now 90% complete. Part of the redesign has meant that there are now dynamic urls in the format: http://www.mywebsite.com/10-pounds-productss/?display=cost&value=10 I have other pages similar to this but with different content for the different price ranges and these are linked to from the menus: http://www.mywebsite.com/20-pounds-products/?display=cost&value=20 Now my questions are: 1. I am using Joost's All-in-one SEO plugin and this adds a canonical tag to the page that is pointing to http://www.mywebsite.com/10-pounds-products/ which is the permalink. Is this OK as it is or should i change this to http://www.mywebsite.com/10-pounds-products/?display=cost&value=10 2. Which URL will get indexed, what gets shown as the display URL in the SERPs and what page will users land on? I'm a bit confused so apologies if these seem like silly questions. Thanks

            If a redirecting URL has more value than the website should I move it?

            Client has two website addresses: Website A is a redirect to Website B. It has one indexed page. But this is the URL being used in collateral. It has the majority of back links, and citations everywhere list Website A as the URL. Website B is where the actual website lives. Google recognizes and indexes the 80+ pages. This website has very few backlinks going to it. This setup does not seem good for SEO. Moreover, the analytics data is completely messed up because Website B shows that the biggest referral source is... you guessed it Website A. I'm thinking going forward, I should: Move all the content from Website B to Website A. Setup Website B to permanently 301 Redirect to Website A. Is that the best course of action?
