How search engine algorithms decide which copy is the canonical one is an open question but in most cases it is probably decided by a few simple factors. If one version is older, that will be the canon. If one appears higher in the navigation structure it may be more likely to be the canonical copy, and the site that has the greater authority it will probably be given the benefit of the doubt about owning the original if two versions appear on different sites simultaneously.
The first point to note is pretty obvious- don’t copy content from other websites and post them on your own. Even if you’re honest about where it came from, it’s not good SEO. If you want to, provide a discussion in your own words and a link to someone else’s information. Better yet, do some extra research and write your own article on the same topic. All content on your site should be original. If you don’t have the time or the inclination to write plenty of fresh and optimised content, a search engine optimisation company like us can do it for you. Our SEO services include expert copywriting.
The 310 redirect is a useful tool for avoiding duplicate content between sites you own. Having one copy of some text at mysite.com and one at mysite.co.uk will not help you and isn’t a great strategy either for easy updating or search engine optimisation. Canonical issues will result in one copy ranking poorly, so use a 301 redirect to transfer users from one site to content on the other rather than maintain separate copies. It’s discussed in a blog post of its own if you want to learn more about it.
It’s sometimes difficult to avoid canonical issues within your own site. Say you take product descriptions direct from manufacturers, and some products appear more than once on the site in different categories. Short of writing two or more different descriptions for each product, which is time consuming for retailers with a lot of products or frequently updated stock lines, what can you do to avoid canonical complications?
Redirection can be tricky in that sort of environment. In 2009, Google, Yahoo and some other search engines introduced support for the canonical link tag. This is very simple to use, and just tells crawlers that what’s behind a link is a copy of a canonical original that appears elsewhere on the site. It doesn’t work across domains, so you will still need to use a 301 redirect for that, but within a single site the canonical link tag is very useful.
