We’ll talk about content in much more detail in the lessons in section 5, but it’s important to cover the technical aspects of content as well. Many digital marketers talk about a duplicate content penalty – but it’s actually not a penalty. Google rewards unique content, it doesn’t penalize duplicate content.

From a technical standpoint, you’ll need to understand how duplicate content can unintentionally be added to a site. Many times, it’s simply a canonicalization issue. For example, homepage canonicalization causes most duplicate content issues on sites.

Without proper canonicalization, your site’s home page actually has 4 different URLs. You could reach your content from

* Domain.com
* www.domain.com
* domain.com/index.html
* or www.domain.com.index.html

Google will see each URL as a different page – and it won’t know which one you prefer to send users to. The problem can get exponentially worse if it exists on every page on your site.

The easiest way to solve the problem is with a server side redirect that sets one of those URLs as the “official” version of the page, and only serves that version, regardless of which URL was the destination.

You can also use the rel canonical tag – it’s a directive that’s inserted in the header of the page. It looks like this: rel=’canonical’

When you’re starting SEO on a new site, you’ll want to check out all of the canonicalization that’s been declared, so that you have a solid understanding of what’s going on with the site content.
