Domain name registrar is a company that for all intensive purposes has a license to offer a domain registration service for end users. Domain name registrars buy domain names directly from Domain Name Registries and are also accredited by the Internet Corporation for Assigned Names and Numbers (ICANN) or by a country code top-level domain (ccTLD) authority.
Domain Optimization
Domain Parking Optimization is the process of matching the best and most relevant PPC ads on your Parked Domains to the intent of the visitors going to that domain. Basically, if your domain is about “used cars”, then you should be displaying PPC ads about “used cars” and not some generic ads about Travel, Software, Music… etc…
The intention is to make sure that the visitor is present with the closest matched options for what they are looking for. By doing so, they are more than likely to click on one of the ads, which results in generating domain parking revenues.
