Background of the issue:
I'm testing WPML on a new site called 'Sitio en desarrollo'. I have both Yoast and WPML SEO plugin installed.
Symptoms:
Canonical tag is not being created automatically.
Questions:
Please could you confirm if WPML should be creating the canonical tag?
If WPML should create the canonical tag, am I missing some configuration?
If WPML does not create the canonical tag, can you give any advice about how to get the canonical tag on my pages?
I understand your concerns. Please note that with Yoast SEO active, all SEO data—such as canonical tags, sitemaps, and Open Graph data — will be managed entirely by Yoast SEO. However, if you’re not using the Yoast SEO plugin, then WPML will handle canonical tags and other essential data in the Head tag.
Since Yoast SEO is active on your site, canonical data should automatically be added when you create a post or page. If you’re experiencing canonical issues on translations, it might be due to the WPML SEO plugin not being activated. According to the WPML debug info, the WPML SEO plugin appears to be deactivated.
Please start by activating the WPML SEO plugin. After that, run the Yoast SEO optimization and check again. You can also create a new page, translate it into the other language, and then verify if the canonical URLs are displaying correctly.
Let me know the update. I'll be happy to help if you need further assistance in this matter.
Finally the problem was that this is a testing site and WP was configured to block robots, so noindex was set on all pages, and Yoast doesn't add canonical tag for pages with noindex.
Now I'm struggling to set up hreflang x-default correctly:
EN is the default language for this site.
1. For any post in any language that has an EN version, I would like to set x-default with the EN version for all languages.
2. For any post in any language that hasn't an EN version, I would like to set x-default with homepage in the default language (EN).
Apparently the default behaviour is that, in there isn't a version in EN, x-default is not set for the rest of languages.
I'm glad you've identified the cause of the canonical not updating correctly.
In response to your other query: when a post or page in another language isn’t connected to the default language version, it won’t have the x-default value.
However, we’re aware of this scenario and have taken it as a feature request to set the default homepage or page link as x-default. In the meantime, we’ve suggested a code workaround in the response below. Please follow the suggestion, and I hope it will be helpful.
