"Valuable (legitimate) domains are often paid for several years in advance, while doorway (illegitimate) domains rarely are used for more than a year. Therefore, the date when a domain expires in the future can be used as a factor in predicting the legitimacy of a domain and, thus, the documents associated therewith."
Domains registered for longer periods give the indication, true or not, that their owner is legitimate. Google uses a domain's length of registration when indexing and ranking a Web site for inclusion in their organic search results.
Unfortunately they're not actually checking for length of registration. Given the text in the first paragraph, they're looking for "expiration_date - NOW", not "expiration_date - registration_date", which I think is more useful.
My domain expiring in 6 months is not as useful as knowing that the domain has been registered for 10 years, imo.
