Welcome to the Q&A Forum

Depends ... do you WANT the brands to compete with each other? That might sound strange but it really isn't. Mabye the three brands have some feature that separates them from each other and makes them uniquely suitable for a different target group. Then it might not be bad to have all three rank for slightly different (long tail) terms AND each for the generic overall term. The brands itself also may carry different values; answering in a vacuum on what I would do is hard to impossible. Nico
