Hi, we are doing a migration from SharePoint CMS to Optimizely CMS. We are migrating over existing urls, so the pages in Optimizely will have the same url as in SharePoint CMS. Is it possible to force the ranking of pages when going over to Optimizely in terms of SEO for external search page (google, etc) after launch?
If the brand new Optimizely site will have the exact same URL (including domain name) as your SharePoint-site, I don't think Google would care when you switch DNS from one site to another.
I'm no SEO expert, but my guess is that as long as the complete URL and the content is the same, Google doesn't care if you update your design or swap out the CMS.
