I just bought some new domains and don't plan to use them until a year from now. I wonder what I need to do with them NOW (from SEO perspective) so that it will be ready to go in a year. The reason I bought it now is to avoid Sandbox effect.
Perhaps you can start a mini website and build it really slowly. The sandbox effect generally puts a new site in limbo for only a few months max so it shouldn't hurt you to start getting some good search engine traffic first before planning on your next big plan for the domains.
