Here's a free windows program I wrote: http://www.rtsoft.eu/products/domainvoyager/ All you have to do is to enter a list of keywords, and it will return a list of targeted dropped domains that you can sell, use as your site's domain, redirect to your main domain, use in a high quality PBN or whatever else. This is a beta program, so all I ask in return is that you message me your suggestions.
