I just had a situation where I answered several questions to be told I qualify for a survey than in the next screen to be told I've already taken the survey.
I am trying to stay on the positive side and believe the more information they get the more surveys I will get ( maybe).
I don't think survey approvals have anything to do with the information you have previously provided. On the contrary, you want to clear your cookies and past history before you start each session to give yourself the best chance of qualifying for new surveys. You want to be anonymous (for each session anyway) and exhaust all your chances to qualify for a survey...any survey...one's as good as another! Also, wait a bit, clear your browsing history again, and attempt the daily surveys all over again. I'll often try all six sponsors in the morning, have no luck, then go back in the afternoon or evening and score! The sponsors do vary the surveys randomly (I believe), even on the same day.
Demographics count, of course, but so do personal interests and past purchases, etc. You run into the same qualifying questions quite often too, so sometimes you'll know you're not going to qualify for that one. You've seen it before. Deja vu. Better luck with the next one. Just be patient and persistent and eventually...cha ching! At least that's been my experience.
