<p><strong><a href="http://googlewebmastercentral.blogspot.com/2009/02/specify-your-canonical.html">Specify your canonical</a></strong></p> You can now use a link rel=“canonical” to tell Google that a page has a canonical URL elsewhere. I’ve run in to this problem a bunch of times—in some sites it really does make sense to have the same content shown in two different places—and this seems like a neat solution that could apply to much more than just metadata for external search engines. <p>Tags: <a href="https://simonwillison.net/tags/canonical">canonical</a>, <a href="https://simonwillison.net/tags/google">google</a>, <a href="https://simonwillison.net/tags/metadata">metadata</a>, <a href="https://simonwillison.net/tags/relcanonical">relcanonical</a>, <a href="https://simonwillison.net/tags/search-engines">search-engines</a>, <a href="https://simonwillison.net/tags/seo">seo</a>, <a href="https://simonwillison.net/tags/urls">urls</a></p>
