P.S. - I wonder what percentage of domains are allowed to expire after the first year. Has anyone seen any data on this?
I know experience isn't worth much here (in lieu of dry scientific peer-reviewed studies!), but I'll throw in my own experiences.
I run a number of niche directories. They are themselves a number of years old. Depending on the directory, between 8% to 15% (I keep stats) of domains that have come through these directories expire (their domain name expires) within a year of their submission to the directory (it's a yearly paid review). I know that doesn't necessarily mean all of these domains were newly registered. Of course, a company may run for 5 years, renew each year, then not renew their domain for the 6th year. However, what I DO know is - there is a significant churn of domain names on the internet.
Now this is AFTER turning away all the thin affiliate / MFA sites that submit listings (these are not counted or listed on my directories, they're simply deleted). I imagine a BIG portion of those affiliate/MFA types of sites do not renew within a year. So, the 8% to 15% refers to sites that "pass muster" and get accepted in my directories. The variation (8 to 15%) shows some niches have more churn than others - health and travel-related have a lot of churn.
