While not the most talked about SEO problem , URL canonicalization is certainly a very important one. Judging by the number of businesses not aware of it I thought a quick post could help clarify what it is and how to fix it.What is a canonical page?
While I could try to explain what canonicalization is myself, I'll just quote Matt Cutts as he is the expert on all things SEO at Google:
"A canonical page is the preferred version of a set of pages with highly similar content"
In SEO terms, this means that a page or set of pages with similar content should only display under 1 URL.
