My wife and I are approaching retirement age. Although our websites make money even without us doing anything to them, so that it might make most sense to keep on running them on a low key basis even after I start receiving a pension, I am something of a workaholic so there is an argument for selling the business when I retire, so I am forced to do something other than spend most of the day sitting in front of the computer constantly trying to improve things.

Is it easy to sell a profitable affiliate business, and is there a rule of thumb for determining its value? I am talking here about an Internet business run from home, using rented web servers, so there are no physical assets apart from computers and software bought by the business; the value would be almost entirely in the websites and the money they make in commissions.
