Hi. PLenty of people have keyword domain they keep just for future project so they won't have problems register good one later due to domainersbuying out most of the good stuff.
So you got good keyword domains but they got no type-in traffic. You don't have time to develop for example 400 domains.
There's solution, company that have good automated minisites, so you keep search engine traffic (unlike with domain parking) and you'll got high CTR.
Basic account is free but suits quite well. Enhanced accounts cost 10$/month or 25$/month and have better templates, more options, you can literaly optimize layout with access to whole html css.
Just join the free account, place 10-20 domains there, and wait few days for indexing and results.
