Clickworker UHRS jobs

I just got onto UHRS jobs for clickworker (african worker so this is the best opportunity for me), I'm looking for tips on the HITs. What would you say are the best(easiest/highest number) HITs? What time should I expect to get the best HITs? Is there anything I can do to increase HITs? Anyone had issues with pay and the like(is it scammy)? Plus anything you could add
