Hi, the number of surveys available will depend on the combination of what our advertisers have available, and whether your personal circumstances match what the advertisers require what is required to qualify. Typically the surveys are directed at a particular group of people looking at criteria such as age, gender, location etc. Unfortunately this is something which is clearly outwith our control. You would normally expect to find more surveys available throughout the week, and then things get a little quieter around the weekend.
