Hello, I have a couple different and well ranked websites offering different products. I have recently decided to combine all of these products onto 1 website vs creating a new website each time we release a new product. Should I do a change of address in webmaster tools and 301 the domains to our new all in one website? If so, will this hurt or help SEO? Again we are well ranked for our keywords on each website however want everyone to eventually merge to one website. Your suggestions are greatly appreciated.
