If you want a ranked website:

1. Post a keyword, the amount you would be willing to pay, and ranking criteria (#1, Top 3, Top 5, or Top 10).
2. Users rank a website for the keyword that you specified.
3. When a user reaches the criteria that you set for the specified keyword, verify that they own the site and submit payment in return for ownership of the website.
