Hello guys. I have forum that is on subdomain of free hosting service. Now I am allowed to have my custom name URL but I worry if I will loose all my SEO gained over many years. So for example my url that is in google very well placed is xxxxmyforumxx.forumhotigtralalal.com and now I am able to have www.xxxxmyforumxx.com
but I was wandering how Google will react if I implement change as my xxxxmyforumxx.forumhotigtralalal.com receives nice traffic and has some good positions for certain keywords.
thanks for your help
