Now that I was finally able to start working M-Turk and am about a week in to it, I thought I'd share my thoughts and experience. So far, I have earned $30 with another $6.75 pending. I am pretty easily making my $5 per day goal, with approximately an hour total worth of time each day.
Currently, (based on a blog recommendation I read) I just do a search of "survey", put in a minimum of .50 and click on HIT's I am qualified for. I have also changed my search criteria to "newest first". That seems to work the best for me. I will usually do a survey first thing in the morning and then do several more during my lunch break.
I still have a bunch to learn on how it all works and will have to figure out how I can get "more qualified" to do other hits. I also read that just getting your volume of completed hits increased helps you get more qualified for other hits. I have done 59 so far, since I started.
About my only frustration is that I have to reenter my search criteria each time. When I complete a hit it takes me back to the main search screen and I have to re-enter my criteria after completing each hit. That takes extra time. I also wish it would keep hits you've already completed from re-appearing.
Overall, I am very happy that it is pretty easy to make my daily goal of $5. I also like that you do not have to enter a bunch of answers and then be told you don't qualify - as always happens with Swagbucks surveys (such a waste of time).
If you are doing M-Turk, I'd love to hear your tips and tricks!
