Would it make any significant temporary problems to change all canonical URLs from relative to absolute?
Would changing of all canonical URLs from relative to absolute temporarily hurt SEO?
seo;canonical url
If search engines indexed exactly the same URLs which you now want to provide as absolute references, there is no reason to assume that the change affects anything. Its just a different way to specify URL references in the href attribute, but the end result is the same.However, if your current relative references result in absolute URLs different from those which you intend to specify now, indexed URLs might change. Examples when this could be the case:if you have specified a base element (it only affects relative references)if your site is accessible from different hostnames (with www and without www, via HTTPS and via HTTP, multiple domains, )
