Why do I need canonical URL tags?

Canonical URL tags help search engines and social media platforms to help identify the ‘original’ version of any page on your website.

Whenever your content can be viewed on different URLs (for example, when a product is in three different categories, or when you use campaign parameters in your URLs), the canonical URL tag tells search engines which the ‘correct’ URL for that page is.

Yoast SEO automatically includes a canonical URL tag on all of your pages and templates. This helps Google, Facebook, Pinterest and other platforms understand exactly how your site is structured, and can help you to solve duplicate content issues.

They consolidate link value

If you’ve done all the hard work required to get people linking to your pages, then you want to make sure that those links count. If you’re not using canonical URL tags, then links to different versions of your pages might mean that their value is diluted.

With a canonical URL tag in place, Google understands that the links to all of those different URLs should be counted against the original version. That means that instead of having lots of weak pages with few links, you have one strong, single page, which all of the links point to.

They prevent internal competition

When search engines get confused, those different ‘versions’ of your pages might end up competing against each other – even from within your own site.

That makes it really important to tell Google which of these is the original version. Then they can combine the value of each of those versions into one single, strong page.

They help improve your search engine listings

When Google displays your pages in their search results, you want to put your best foot forward. Canonical URL tags help to tell Google which URL they should show, and where they should send visitors when they click. 

Remember, the search engine results page is your shop front, and, every detail matters when it comes to convincing users to click on your listing! Sending visitors to the wrong version of a page, or showing confusing text in your snippet might confuse or frustrate your visitors.

They consolidate social shares

It’s not just Google that uses canonical URL tags – social networks like Facebook, Pinterest and more also rely on understanding which the original version of the page is.

When somebody shares your page, you want to make sure they’re sharing the right version. Canonical URLs make sure that you’re tallying up those share counts against the original version of your page, instead of splitting up your scores against lots of different URLs.

Extra Yoast canonical URL features

We let you manually change the canonical URL

In some cases, you might want to choose your own canonical URL on a page. Our plugin lets you do this on a page-by-page basis, and it’s as easy typing in the URL you want to use.

We also support cross-domain canonical URL tags, so you can reference pages on other websites. This might be useful if your content is published on multiple sites, and you want to prevent those pages from competing with each other. Setting a cross-site canonical URL can help to achieve this by consolidating links and social shares to a specific page.
