Ratios don't mean anything. When I buy e.g. 10,000 hits a day for let's say 5 cent per click and send this traffic directly to a sponsor that pays $40 per signup I make enough profit with a ratio of 1:300, i.e. $25 per signup and about $800 a day.
Of course I could try to get better ratios but some traffic just doesn't convert better. I rather spend that time to get another traffic deal with above profit
