John Mueller, a Google Webmaster Trends Analyst, announced that Google is migrating all their official blogs off the blogspot.com domain name and onto the more official googleblog.com domain name. The reason is to help users understand that these are official blogs managed and operated by Google.
The migration began with Google’s very own Google Webmaster Blog which is now available at https://webmasters.googleblog.com/. The original URL was googlewebmastercentral.blogspot.com, and now that redirects using a 301 redirect to webmasters.googleblog.com.
Google plans on migrating all of their blogs to googleblog.com over the next several months.
John Mueller added that “the previous address will redirect to the new domain, so your bookmarks and links will continue to work.” The RSS feeds and comment URLs will not redirect, and you will need to resubscribe to those separately.
Of course, many SEOs are eager to see how the migration goes from an SEO perspective for Google.
