Before doing a valuation, how would you answer the below questions:
Is there search volume? CPC?
What have similar domains sold for in the past?
Are there companies who would call themselves that or product or services that would call themselves that?
Can you see the domain being used in a commercial on the radio, tv, or on billboard?
Why would someone pay you $100s or $1000s for this domain instead of hand regging something more appropriate to their business, or shorter?
Why do you personally think this domain has value?
