Setting a global canonical page URL in Webflow is not necessary if you have unique content on each page of your website. The purpose of a canonical URL is to inform search engines about the preferred version of a webpage when multiple URLs have the same or very similar content.
If every page on your website has its own unique content, there is no need to implement a global canonical URL. Search engines will treat each page as an individual entity and index them accordingly.
However, if you have pages with similar or duplicate content, setting canonical URLs becomes essential. It helps search engines understand the relationship between those pages and consolidate their rankings. In such cases, you can specify the canonical URL for each page to point towards the preferred version, which ensures that search engines give preference to that URL while indexing.
To set a canonical URL in Webflow, you can navigate to Page Settings for each page and input the desired canonical URL in the "Canonical URL" field. It's important to note that the canonical URL should be an absolute URL, including the "https://" or "http://" and the domain.
In summary, if your website has unique content on every page, you can omit setting a global canonical URL. However, when dealing with similar or duplicate content, utilizing canonical URLs is fundamental for optimizing search engine rankings and avoiding duplicate content issues.
