      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?

        Some browsers might hide the www and htttp part from the url . Just to make sure pop your sites url in there ( http://www.webconfs.com/http-header-check.php ) and see if there is a redirect.

        Rel canonical : does NOT redirect the pages .. its just there for search engine bots. Think of it this way

        You would want to use rel canonical where you need to show the duplicate pages for users .. eg : on a shopping website sort by A-Z , by Price , Z-A, etc could all display the same things in different order BUT users benefits from having those so use a rel canonical there to tell the spider its all the same version of your " original page " . There is no redirects here users can see all the multiple versions of the page. If they are redirected what is the use of sorting those results ?

        I would also like to know why OSE does that ( some one from the staff could possibly answer that )

        In regards to your question : Should my non WWW be redirecting to my WWW ?

        You should only allow one version it can either be non WWW or WWW. In your case stick with the one that has more authority and do a 301 redirect for the other one.

        In regards to your question : Why am I getting two different domain authority and backlink counts ?

        For Google  www.yoursite.com and yoursite.com are 2 different sites on the same domain.

        Hope that made things more clear for you

          Okay... two main points I think here 🙂

          1. Yes, which domain/sub-domain the links are pointing to makes a difference - so if you have a www version and your links point to the non-www version then it's not quite as great. (Still has value for your site, though, it's important to remember). So you need to decide which is the most important and keep the canonicalisation (is that a word?) consistent throughout.
          2. In Wordpress you should be able to change the direction of the redirect, have a shuffle around the 'settings' section and you should be able to find it.

          Hope this is helpful.

            How much difference does .co.uk vs .com for SEO make?

            My Website has a .com domain. However I have noticed that for local businesses all of them have a .co.uk (UK business) TLD (check plumbers southampton for example). I have also noticed that on checking my serp rankings, I'm on page 1 if searched on Google.com but page 2 if searched on google.co.uk. Now being UK based I would assume most of my customers will be redirected to google.co.uk so I'm wondering how much of an impact this actually makes? Would it be worth purchasing .co.uk domain and transferring my website to that? Or run them both at the same time and set up 301 direct on my .com to .co.uk? Thanks

            Link rel="prev" AND canonical

            Hi guys, When you have several tabs on your website with products, you can most likely navigate to page 2, 3, 4 etc...
            You can add the link rel="prev" and link rel="next" tags to make sure that 1 page get's indexed / ranked by Google. am I correct? However this still means that all the pages can get indexed, right? For example a webshop makes use of the link rel="prev" and ="next" tags. In the Google results page though, all the seperate tabs pages are still visible/indexed..
            http://www.domain.nl/watches/?tab=1
            http://www.domain.nl/watches/?tab=24
            http://www.domain.nl/watches/?tab=19
            etc..... Can we prevent this, and make sure only the main page get's indexed and ranked,  by adding a canonical link on every 'tab page' to the main page --> www.domain.nl/watches/ I hope I explained it well and I'm looking forward to hearing from you. Regards, Tom

            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.

            Redirect non-www if using canonical url?

            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

            Iframes & SEO

            I've got a client that wants a site with all content in iFrames. They saw another site they liked & asked if we could do it.  Of course we can technically.  How big a negative hit would they take with SEO?  Is there anything we can do to mitigate it, such as redirects, etc? Thanks for the help!

            Syndication: Link back vs. Rel Canonical

            For content syndication, let's say I have the choice of (1) a link back or (2) a cross domain rel canonical to the original page, which one would you choose and why? (I'm trying to pick the best option to save dev time!) I'm also curious to know what would be the difference in SERPs between the link back & the canonical solution for the original publisher and for sydication partners? (I would prefer not having the syndication partners disappeared entirely from SERPs, I just want to make sure I'm first!) A side question: What's the difference in real life between the Google source attribution tag & the cross domain rel canonical tag? Thanks! PS: Don't know if it helps but note that we can syndicate 1 article to multiple syndication partners (It would't be impossible to see 1 article syndicated to 50 partners)
