If I move my blog from subdomain to root, will my blog lose all of its authority? Social signals?

Moving my blog from blog.site.co.uk to site.co.uk/blog and just wondered if all the social data for each post will be lost including the blog authority which has been built up over time?

Is 301 redirects enough to keep any of it?

Rankings were unstable for a couple of weeks but we are back at strength almost everywhere.

And have you seen any impact from an SEO point of view?

Or maybe you will see an impact when search engines take social signals into more consideration?

I think that the question is.... "Will the number of FaceBook likes follow to the new URL or will they be reset?"

I redirected a domain a few months ago and all of my numbers were resent to zero.

Individual pages will lose a tiny amount of page authority, but your domain authority should remain unaffected because all subdomains are included.

301 redirects will maintain about 90% of your blog's authority. The only way to retain it all is to get the links to point to the new URL, which is probably impossible if you have hundreds or thousands of them. Just set up a wildcard redirect that does a 301 of blog.site.co.uk/* to site.co.uk/blog/* so that every page redirects and is maintained. The worst thing you could do here is not transfer some of your content over and leave a bunch of 404's behind.
