I am holding few domains which I am not using from long time and investing on every year. Following are the domains.

My idea is to sell those domains but I have just tried AdSense for domain. The great feature of this product is free. Cash parking is not a good idea for me I am ready to sell those domains. If you are interested for above domains you can submit a comment on same post.

Following are detail of AdSense for domains. (Source: http://www.google.com/domainpark/)

AdSense for domains allows publishers with undeveloped domains to help users by providing relevant information including ads, links and search results.

With AdSense for domains, users can find relevant information rather than see empty pages or “page not found” errors. To ensure positive user experience and the quality of our network, these sites are monitored for policy compliance and prohibited from using text and images designed to confuse users.

AdSense for domains provides advertisers with additional opportunities to find their customers, and ads on these pages convert well. In addition, we regularly receive requests from advertisers who have found domains to be an effective way to reach their users.

If you have undeveloped domains, then AdSense for domains can help your users. To get started, check out our setup instructions, and visit our Help Center for more information.

I will share my experience with this feature very soon.
