      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

            Is 301 redirect the only way when using Vanity URLs?

            We have been using vanity urls for some of our pages. Mostly the pages that have a vanity URL have a long URL length. But now the problem is, the vanity URL is getting displayed on the search engine when the particular keyword related to the page is entered. I checked the google search console, the vanity URL is indexed and the original URL remains unindexed. What should I do? Is adding 301 redirect to the vanity URLs are solution? Since some of vanity URLs are not redirecting to the original. Some of the original pages are not getting traffic. Also, can using canonical tag help?

            Using 410 To Remove URLs Starting With Same Word

            We had a spam injection a few months ago.  We successfully cleaned up the site and resubmitted to google.  I recently received a notification showing a spike in 404 errors. All of the URLS have a common word at the beginning injected via the spam: sitename.com/mono
            sitename.com/mono.php?buy-good-essays
            sitename.com/mono.php?professional-paper-writer There's about 100 total URLS with the same syntax with the word "mono" in them.  Based on my research, it seems that it would be best to serve a 410.  I wanted to know what the line of HTACCESS code would be to do that in bulk for any URL that has the word "mono" after the sitename.com/

            Best Practice for www and non www

            How is the best way to handle all the different variations of a website in terms of www | non www | http | https? In Google Search Console, I have all 4 versions and I have selected a preference. In Open Site Explorer I can see that the www and non www versions are treated differently with one group of links pointing to each version of the same page. This gives a different PA score. eg. http://mydomain.com DA 25 PA 35 http://www.mydomain.com DA 19 PA 21 Each version of the home page having it's only set of links and scores. Should I try and "consolidate" all the scores into one page? Should I set up redirects to my preferred version of the website? Thanks in advance

            Is it better to use XXX.com or XXX.com/index.html as canonical page

            Is it better to use 301 redirects or canonical page? I suspect canonical is easier. The question is, which is the best canonical page, YYY.com or YYY.com/indexhtml? I assume YYY.com, since there will be many other pages such as YYY.com/info.html, YYY.com/services.html, etc.

            Having www. and non www. links indexed

            Hey guys, As the title states, the two versions of the website are indexed in Google. How should I proceed? Please also note that the links on the website are without the www. How should I proceed knowing that the client prefers to have the www. version indexed. Here are the steps that I have in mind right now: I set the preferred domain on GWMT as the one with www. I 301 redirect any non www. URL to the www. version. What are your thoughts? Should I 301 redirect the URL's? or is setting the preference on GWMT enough? Thanks.

            Use webmaster tools "change of address" when doing rel=canonical

            We are doing a "soft migration" of a website.  (Actually it is a merger of two websites). We are doing cross site rel=canonical tags instead of 301's for the first 60-90 days.  These have been done on a page by page basis for an entire site.  Google states that a "change of address" should be done in webmaster tools for a site migration with 301's.   Should this also be done when we are doing this soft move?

            Trailing Slashes In Url use Canonical Url or 301 Redirect?

            I was thinking of using 301 redirects for trailing slahes to no trailing slashes for my urls. EG: www.url.com/page1/ 301 redirect to www.url.com/page1 Already got a redirect for non-www to www already. Just wondering in my case would it be best to continue using htacces for the trailing slash redirect or just go with Canonical URLs?
