Canonicalisation is often as a complex and confusing process but it’s an integral part of a SEO process, especially if you are moving content while redesigning or restructuring your website. Google really simplified the definition of canonicalisation:
A canonical page is the preferred version of a set of pages with highly similar content.
Although people realise it has something to do with SEO it is often confused 301 redirect. Let’s see what it means in practice.
What Does Canonicalisation Mean in Practice?
Let’s take a look at few examples of URL:
Most people don’t notice the difference. Hey, as long as it takes them to the destination, right? Well, for Google and other search engines these are different URL’s. Search engines will crawl your site, index all of your content and then decide which is a preferred version of URL.
Whenever it’s possible you want to be the one that decides what content will be presented in which way. That’s why you want to provide search engines with canonical URL.
Hot To Set Canonical URL?
Setting Canonical URL in WordPress
First of all it’s important that you decide if your site address will be with or without “www” (http://webpage.com or http://www.webpage.com). In WordPress under Settings > General you’ll find the following options:
Enter the preferred URL in both fields. When a user tries to access your site with the other URL they will be redirected to the one you entered here.
Verifying Homepage’s Canonical URL in Google Webmasters Tools
Now it’s time to tell Google the preferred URL using Webmasters Tools. First you need to add both http:// and http://www. versions of your website to your account and then set the preferred one under Configuration > Settings.
Do this on both accounts.
