Domain parking is a very simple system that basically consists of display advertising links in domains without content itself. The theme that will focus the advertising links that will be displayed is usually assigned automatically and will go under the name of the domain. There are currently several companies in which to Park undeveloped domains among which Sedo, Namedrive, Domainsponsor but, is it really profitable to park a domain? Clearly the profitability obtained by a parked domain goes parallel to the visits. If the page of publicity associated with the domain gets a good number of visits the likelihood that these visitors please click on any of the ads with the consequent entry into our favor. Here you will find the biggest problem of the parking of domains: a newly registered domain will just generate visits and promote it, having no content, is frankly difficult. On the other hand, if you have a domain already developed and that you have a good number of visitors, does not seem very valid option to park it. The conclusion that can be drawn is that domains that are really good for parking in any parking space are called typo (or misspelling domains) domains are those domains which are one error of an already existing and to be more popular as possible.
