We have implemented canonical links to our website in order to prevent the indexation of parameters.
Some of the pages are also used as iframes. From the the little info I could find on 'iframes and canonical links' online, I concluded that the iframe itself does not have to include a canonical link. Is this correct?
Also, we implement canonical link as a standard part of the every page that is created. But there is also the possibility to set a page to 'noindex'. Online I find very contracting opinions on this. Some stating that these two are two completely different 'commands' for search engines and others saying that they are contradicting ones.
Does anybody have any advise on these two points?
