In Hump Day Hangouts episode 326, one participant asked how would you deal with existing social profiles and drive stacks if your client decides to rebrand.
The exact question was:
Hi there, say you have client that decides to rebrand and merge multiple websites together or changeover to a completly new brand. For the domains I would 301 everything over to the right place but how would you deal with social profiles and drive stacks? Would you rebuild from scratch? Dont want to waste link juice from the old stacks.
