Micro Jobs sites provide a platform for Employers and Workers where Employers post jobs to urge their work done and micro workers complete the roles to urge money. Micro workers are free to choose microtasks that match their skills the only .
The Employers are asking the worker to end a Sign-up job. The Worker completes the task and submits proof (whatever an employer asks for). The employer checks out his work and if he's satisfied with the work he approves the work and pays an amount of $0.08 to $5 to the worker.
Micro jobs are thus small tasks and wish little or no time and skills to be completed. Doing micro jobs has become one among the only ways to make money online. I even saw how little money adds up to make large. I do know several guys who do great during this field and earning huge money from crowdsourcing sites. Micro job sites are getting better and providing a really easy interface to the users.
