I own avatarthemovieforum.com and avatar-forum.net. For the past year I have used avatarthemovieforum.com. I, however, don't rank for "avatar forum". The second main forum in my niche's domain is avatar-forums.com. Would it be beneficial to change my primary domain to avatar-forum.net, even though my competitor uses a similar domain? Thanks!
It depends where your stand for avatarthemovieforum.com ... You have not given the details and PR. Anyways, I think rater than focusing on some other domain, you have to concentrate firstly on the first domain.
