Our company has 40 or so individual businesses which each have their own individual domain names. These websites have been established for 10 years or more and rank nicely for their (well known) brand names, with organic site links visible.
Our new corporate business strategy is that each of these individual businesses will take a new umbrella brand name, append to it current business name, and all the sites will move to one corporate domain name.
Of course we'll permanently redirect the old sites to the new, but is there anything else we can do to maintain the individual strength of these websites (particularly their organic site links) or do we have to expect that visibility for each individual business will be reduced in this new strategy?
Grateful for any hints or tips or past experience you can share.
