Brand A and Brand B are merging to form Brand C. Brand A has a great search presence (prominent rankings, answer boxes, and impressive organic traffic). Brand B has a good reputation in real life but their web presence was extremely weak (we've been helping with that over the past few months and it is improving). What are the steps we need to take? The previous domains from Brand A and Brand B are going away and we need to promote the newly minted Brand C website. This Q/A summarizes what we want to do but with one exception: They only discuss merging Brand A into BRand B and there is no Brand C.
