How much are you paying affiliates for the traffic? How much work do you put into creating marketing tools specifically for affiliates? How much does support of the affiliates cost? What is the percentage margin of profit on affiliates vs organic efforts/internal traffic?
It comes down to the numbers. Most affiliate focused programs die because they pay too much for the traffic and the margins are not profitable enough to sustain operations, and the programs literally implode with success. Many of the giant affiliate programs of the so called "golden age" of internet porn collapsed under the same system that brought them success back in the day.
For that reason, it is way better to look for quality over quantity when it comes to acquiring affiliates imho. I would think making your current 92% of unproductive affiliates more successful would be easier than trying to pull in new affiliates that might have the same ratio of un-productivity and therefore create more strain on your resources.
