What steps does one have to take before purchasing an online business? There are many steps that are obvious to me, like: *asking for proof of traffic and revenue *cost of basic necessities to run business *proof of ownership *asking for a reason of sale etc... Obviously a site that is making some one money isn't going to be sold very cheaply, so that's a sign to look out for... What other steps do you take before buying a business / revenue earning site?
