# How to change the canonical URL in Yoast SEO for WordPress

Yoast SEO adds [canonical URLs](/content/rel-canonical/index.html) to your WordPress site: if you have multiple posts or pages with similar content, it tells the search engines what URL contains the original content. In some cases, you may want to change the canonical URL of your WordPress site manually. In this article, we’ll explain how you can change the canonical URL if you have Yoast SEO for WordPress.

## How to change the canonical URL

To change your canonical URL in WordPress, follow the steps below

1. **Log in to your WordPress website**  
You are now in your _Dashboard_.

2. **Go to the _Post_, _Page_, _Category_ or _Tag_ for which you want to change the canonical URL**  
You are now in the editor of the _Post_, _Page_, _Category_ or _Tag_.

3. **In the Yoast SEO sidebar, go to _Advanced_**

4. **In the _Canonical URL_ field, enter the full canonical URL**  
You must include the full address, including http; https; www; or non-www at the beginning of the URL.

5. **_Publish, Save_, or _Republish_ your post to change your canonical URL**  
When you publish your revised post, including the canonical URL, the changes are applied.

## How to filter the canonical output programmatically

If you have experience with coding, you can also filter the output programmatically. To do this, you can use the `wpseo_canonical` filter. If you return false on that, no canonical will be output. We have provided [several examples](https://gist.github.com/amboutwe/2aa7dcc9a38986e11fac68c7306cc091).

## I have a problem with changing the canonical URL

In some cases, you may not see a canonical tag output on a page. In this case, check if the page has a [`noindex`](/content/help/how-do-i-noindex-urls/index.html) tag. We do not output a canonical tag if the page is marked as `noindex`. To resolve the issue, mark the pages as `index`.
