Webpage and canonical link tag points to different URLs

To know how you can change the canonical URL, please check this article: https://kb.yoast.com/kb/canonical-urls-in-wordpress-seo/

To know the SEO-benefit of a canonical URL, this article will give you more information: https://yoast.com/rel-canonical/

In the picture you have pasted, I can see settings that are not present in my Yoast plugin, the option to write a conanical is not present. I have already tried to make this change using the filters written in this article but this only caused more problems. Is there another way to do this? Can you write me the code to change only the canonical URL of my home page?

In the picture you have pasted, I can see settings that are not present in my Yoast plugin, the option to write a conanical is not present. I have already tried to make this change using the filters written in this article but this only caused more problems, that code always returns all pages to the main page. As a result all my pages are declared to the root of the domain as URL canonical, when it must be the URL itself.
You can see this example:
https://audioprolabs.com/tutoriales-pro-tools/pro-tools-12/tutorial-pro-tools-12-edicion-de-audio

Google sees as canonical
https://audioprolabs.com

After deleting this code everything seems OK. Is there another way to do this? Can you write me the code to change only the canonical URL of my home page without affecting all the other pages?
best regards

Hi @audioprolabs,

If you click on the gear icon in the Yoast Metabox, you should find the field to change the canonical. See image for reference: https://imgur.com/aCYgGml

If you don’t have this option, can you please send us a screenshot of what you see in your Yoast Metabox settings?

We checked the source code of your frontpage and we see that the canonical URL points correctly to itself. See image located here: https://imgur.com/a/iWc6bn6

Can you confirm if the issue is fixed?

Hello,
doing a test I’m getting this result:
Webpage and canonical link tag points to different URLs.

Website url:
https://audioprolabs.com

Url found in the canonical link tag:
https://audioprolabs.com/

The canonical URL generated by the plugin Yoasthas a bar at the end.
I also have a option to change the canonical on mi Yoast plugin. But my home page can not be manipulated with the plugin because I think it is generated in a dynamic way. How I can solve this problem?

Hi @audioprolabs,

The trailing slash in the URL is controlled by the WordPress settings. Please go to Settings -> General and check if the Site Address and WordPress Address have the trailing slash.

If the issue persists, the canonical tag might be output by another plugin or theme and is overriding the Yoast canonical URL. To check, please perform a conflict check following the steps here.

There might be a conflict with another plugin or your theme because looking at the source code of your homepage, we see that there are duplicate sets of tags, like the Twitter and OpenGraph tags.

In the word press settings the site address is without the trailing slash. The canonical URL is generated by the plugin Yoast and no another plugin. Disabling the Yoast plugin I have the following test result:
Webpage has no canonical link tag.

Doing a test with Health Check & Troubleshooting plugin, there is no conflict between plugins or theme. Can you provide me a code to change only the canonical URL of my home page without affecting all the other pages?

By default, WordPress permalinks structure use the trailing slash at the end. Can you please confirm whether your permalinks structure has the trailing slash at the end of it? You can check this from your site permalinks structure settings.

Notice that even if your permalinks structure has no trailing slash on it, Yoast SEO will still use the trailing slash at the end of the canonical URL for your site front page URL. The front page URL always have the trailing slash at the end of this. So, if you are testing your site using a 3rd party tool, please make sure that you include the trailing slash at the end of your site URL.

Hello,
my wp permalinks structure does not have at the end the trailing slash. If I include the trailing slash at the end of my site URL there in no problem using a 3rd party tools. I was thinking that the right way to write my site URL is without the trailing slash doing these tests.

The base URL of a site will always include the trailing slash at the end of the URL and which is why Yoast SEO is adding the trailing slash at the end of the base URL only.

So it’s all OK, and I don’t have to worry about it?

Right, it’s completely fine and nothing to worry about.

Ok, thank you very much for your help.
best regards
