I have a relatively new price aggregation website (online for about one month). Part of it was also adapted (custom header/footer) and included into an older site, on a different domain, which already has a Google PageRank, and domain authority.
In order to prevent duplicate content and to promote the main website, the integration contains canonical-url links on the old website pointing to the respective website pages on the new domain.
From a SEO point of view will any rank juice be passed from the older website and domain (which contains the integration) to the new one through the canonical links? Or is it better to just add "dofollow" links from the integration to the main website?
