As others mentioned, age alone isn't enough to determine sustainable liquidity in a domain name. Granted, one could technically multiply the years of age by the current renewal cost of the TLD to get an idea of what you could stack on-top of other value metrics, but rarely will that apply if it's the only metric of value being considered,
The only real bonus to an aged domain is that it's now seasoned enough to be favored a little more in SERPs and to potentially run an outbound campaign (E.g. newsletters, customer notifications, sales outreach, etc..).
For instance:
- Newly registered domains are generally flagged in an email blacklist for the first 5 days
- Newer domains are also flagged as suspicious for up to 30 days
- Newer domains are throttled (Sometimes) if they exceed 10 emails daily within 60 days
- Newer domains are throttled (Sometimes) if they exceed 25 emails daily in the first 90 to 120 days
- At 6 months a domain is considered seasoned and actually ready for a larger scale email campaign
Note: It's generally best to warm up a domain for email for the first year, with the renewal signaling that the domain isn't going to be a fly-by-night spam agent.
With 5, 10, 20+ year aged domains, you can pretty much bypass most that warmup phase as long as the previous owners didn't already get the domain added to an email black list somewhere, banned, or penalized. Which is why it's important for an acquisitions team to check those types of stats to insure their client needing email outreach to their customers and potential clients can actually reach them.
Unfortunately, most acquisitions happen without checking a domains ranking data and stats, leaving the buyer in a lurch down the road when they go to launch and run into speed bumps.
That's my thoughts, anyways...
