      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

            Canonical tag use for ecommerce product page detail

            Hi, I have a category page I want to rank. This page has 24 different products quite similar but not exactly the same.
            I want to use canonical tag in any product to the parent category. 
            Is this a right use of the canonical? 
            Category page I'm talking about is : Finger bits If I understand how to use canonical tags I can improve all my category pages. thanks marco

            Category URL Pagination where URLs don't change between pages

            Hello, I am working on an e-commerce site where there are categories with multiple pages. In order to avoid pagination issues I was thinking of using rel=next and rel=prev and cannonical tags. I noticed a site where the URL doesn't change between pages, so whether you're on page 1,2, or 3 of the same category, the URL doesn't change. Would this be a cleaner way of dealing with pagination?

            Is there any benefit in using a subdomain redirected to a single page?

            For example if we have a domain www.bobshardware.com.au and we setup a subdomain sydneysupplies.bobshardware.com.au and then brisbanescrewdrivers.bobshardware.com.au and used those in ad campaigns. Each subdomain being redirected back to a single page such as bobshardware.com.au/brisbane-screw-drivers  etc. Is there a benefit ? Cheers

            Mobile URL parameter (Redirection to desktop)

            Hello, We have a parallel mobile website and recently we implemented a link pointing to the desktop website. This redirect is happening via a javascript code and results in a url followed by this paramenter: ?m=off Example:
            http://www.m.website.com                                 redirects to:
            http://www.website.com/?m=off Questions: Will the "http://www.website.com/?m=off" be considered duplicate content with "http://www.website.com" since they both return the same content? Is there any possibility that Google will take into consideration the url ending in "/?m=off"? How should we treat this new url? The webmaster tools URL parameter configuration at the moment isn't experiencing problems but should we submit the parameter anyway in order not to be indexed or should we wait first and see the error response? In case we should submit this for removal... what's the best way to do it? Like this? Parameter: ?m=off Does this parameter change page content seen by the user? - doesn't affect page content Any help is much appreciated.
            Thank you!

            Using a non-visible H1

            I have a developer that wants to use style="text-indent:-9999px" to make the H1 non-visible to the user.  Being the conservative person I am, I've never tried this before and worry that Search Engines may think this is a form of cloaking.  Am I worrying about nothing?  And apologies if it's already been covered here.  I couldn't find it.  Thanks in advance!!!!

            Hreflang on non-canonical pages

            Hi! I've been trying to figure out what is the best way to solve this dilemma with duplicate content and multiple languages across domains. 1 product info page 2 same product but GREEN
            3 same product but RED
            4 same product but YELLOW **Question: ** Since pages 2,3,4 just varies slightly I use the canonical tag to indicate they are duplicates of page 1. Now I also want to indicate there are other language versions with the_ rel="alternate" hreflang="x" _element. Should I place the _rel="alternate" hreflang="x" _on the canonical page only pointing to the canonical page with "x" language. Should I place the _rel="alternate" hreflang="x" _on all pages pointing to the canonical page with the "x" language? Should I place the _rel="alternate" hreflang="x"  _on all pages and then point it to the translated page (even if it is not a canonical page) ? /Lars

            Old URL redirect to New URL

            Alright I did something dumb a year a go and I'm still paying for it. I changed my hyphenated URL to the non-hyphenated version when I redesigned my website. I say it was dumb because I lost most of my link juice even though I did 301 redirects (via the htaccess file) for almost all of the pages I could find in Google's index. Here's my problem. My new site took a huge hit in traffic (down 60%) when I made the change and even though I've done thousands of redirects my old site is still showing up in the SERPS and send much if not most of my traffic. I don't want to take the old site down in fear it will kill all of my traffic. What should I do? Is there a better method I should explore then 301 redirects? Could the other site be affecting my current rank since it's still there? (FYI...both sites are built on the WP platform). Any help or ideas are greatly appreciated. Thank you! Joe

            Do search engines treat 307 redirects differently from 302 redirects?

            We will need to send our users to an alternate version of our homepage for a few hours for a certain event. The SEO task at hand is to minimize the chance of the special homepage getting crawled and cached in the search engines in place of our normal homepage. (This has happened in the past so the concern is not imaginary.) Among other options, 302 and 307 redirects are being discussed. IE, redirecting www.domain.com to www.domain.com/specialpage. Having used 302s and 301s in the past, I am well aware of how search engines treat them. A 302 effectively says "Hey, Google! Please get rid of the old content on www.domain.com and replace it with the content on /specialpage!" Which is exactly what we don't want. My question is: do the search engines handle 307s any differently? I am hearing that the 307 does NOT result in the content of the second page being cached with the first URL. But I don't see that in the definition below (from w3.org). Then again, why differentiate it from the 302? 307 Temporary Redirect The requested resource resides temporarily under a different URI. Since the redirection MAY be altered on occasion, the client SHOULD continue to use the Request-URI for future requests. This response is only cacheable if indicated by a Cache-Control or Expires header field. The temporary URI SHOULD be given by the Location field in the response. Unless the request method was HEAD, the entity of the response SHOULD contain a short hypertext note with a hyperlink to the new URI(s) , since many pre-HTTP/1.1 user agents do not understand the 307 status. Therefore, the note SHOULD contain the information necessary for a user to repeat the original request on the new URI. If the 307 status code is received in response to a request other than GET or HEAD, the user agent MUST NOT automatically redirect the request unless it can be confirmed by the user, since this might change the conditions under which the request was issued.
