<p>My links back to the old I-buy-Spy Microsoft <span class="caps">CMS</span> system are getting more removed as the MS-Office Live SB websites are shutting down tomorrow. They offered their Office 365 alternative at a reasonable rate but did not provide porting tools and <span class="caps">SEO</span> still required bodging.</p>
<p>So I re-hosted my website in Europe where my new provider’s free domain name offer included .eu domains so I claimed <a href="http://ppcpromotion.eu/">ppcpromotion.eu</a> .</p>
<img style="float:right;padding-left:5px;" src="http://blogs.warwick.ac.uk/images/robmcgonigle/2012/04/29/duplicate-content.png?maxWidth=500" alt="Duplicate Content Barred" title="Duplicate Content Barred" border="0" />When selecting my main domain I also registered <a href="http://ppcpro.co.uk/">ppcpro.co.uk</a> to have a shorter domain for the phone and email addresses.<br />
Then I registered the ‘dash’ variants;
<ul>
<li> <a href="http://ppc-pro.co.uk/">ppc-pro.co.uk</a> </li>
<li> <a href="http://ppc-promotion.co.uk/">ppc-promotion.co.uk</a> </li>
</ul>
<p>This now adds up to 5 domains that instantly gets doubled when you add the www. variants which are treated as sub-domains like<a href="http://wrap.warwick.ac.uk/">wrap.warwick.ac.uk</a> the University of Warwick, Research Archive Portal.</p>
With Microsoft I could use the three main ways to manage the <span class="caps">DNS</span> settings: <ol>
<li>Donating the Domain names to the host’s Nameservers.</li>
<li>Directing the domain to the Host’s server’s IP address, using ‘A’ or Address Records.</li>
<li>Pointing one hostname to another using <span class="caps">CNAME</span> Records or Canonical name records.</li>
</ol>
<p>My new host only allowed new domains to be added using A records.<br />
I could still have used <span class="caps">CNAME</span> or simple redirection externally from the server but since I already had .eu and .co.uk that <span class="caps">MUST</span> be managed this way, already 4 domains I needed to solve the duplication problem.</p>
<p>I halved the problem by adding canonical links in the page headers but these cannot work across domains so this can only manage the www. duplication.<br />
These links looked like this:<br />
link rel=”canonical” href=”http://ppcpromotion.co.uk/”/<br />
link rel=”canonical” href=”http://ppcpromotion.co.uk/adwords-audit”/<br />
(You will need to add the < and > characters around these lines. I removed then so these will show on this Blog.)</p>
<p>Actually there is hope for the .eu and .co.uk duplication from Google’s Webmaster Tools help :</p>
<p>“In a situation like this, you can use the rel=”canonical” link element across domains to specify the exact <span class="caps">URL</span> of whichever domain is preferred for indexing. While the rel=”canonical” link element is seen as a hint and not an absolute directive, we do try to follow it where possible.”</p>
<p>I experimented with <span class="caps">CNAME</span> Records but I needed to be able to finish the job off on the server so the three minor domain names were simply used 301 Permanent redirection as the cleanest, safest solution.</p><p class="answer">Writing about web page <a href="http://ppcpromotion.co.uk/en" title="Related external link: http://ppcpromotion.co.uk/en">http://ppcpromotion.co.uk/en</a></p>
