Global canonical tag URL and Page Override
A canonical in an embed element may be in the side body. Move the relevant output to the appropriate head configuration and publish again.
Compare the global base URL with the published standard domain. Webflow combines this base with the respective page path. A canonical for a static page or additional custom code can deviate from this.
Where to check the setting in Webflow
Under Site settings → SEO, check the Global canonical tag URL and additional canonicals at the page level or in the custom code. The global value describes the preferred base; a second individually inserted output must not point to another landing page.
Example of this specific finding
Illustrative control case: A widget inserts a body element into the head before the canonical. The browser repairs the HTML and assigns subsequent elements differently.
follow-up audit in Webflow
Test a static page and a collection item after publication. Do not add another canonical edition via Tag Manager or Custom Code if the native edition is already in charge.
Check both original HTML source text and parsed DOM. Fix the invalid build on the causing component and output the canonical in the valid head.
Derogations and scope
A pure source text search for the word canonical does not reliably detect this structural error.
Reference: Websites published on Webflow and CMS Collections. Exported HTML or an upstream own proxy layer may have other responsibilities.
