Building a marketplace for domain names

I’ve been working on a project focused on the problem of buying and selling domain names.

The basic idea is to give domain owners a place to list names they’re willing to sell and allow people looking for a particular domain to find and communicate with the owner directly.

One part I’ve been thinking about a lot is the process itself. Finding a domain is often easy; finding the right owner, starting a conversation, negotiating, and getting the transaction completed can be a different story.

I’m also experimenting with adding useful tools around domains, websites, SEO, and online content rather than making the project only about domain listings.

It’s a finished project.

What part of building a project like this would you focus on improving first?
