Aside from Data Entry job, another good online freelancing job is Transcription or Transcribing. It is a kind of job wherein you would listen to an audio or video clip and then writing everything that you hear from that certain clip. It also depends on what your client needs as well. Some may want to have you write everything that you hear and see specially the minor details, and some just want to know the specific words or conversations.
Mind you, this job can get very challenging though. This requires sharp and attentive minds and good ears! Literally good hearing is needed although there are softwares provided that would let you control the audio or video such as lowering it's speed, increasing the volume or panning the stereo channel.
Is this job your forte? Are you interested in trying this kind of job? Or have you tried it already? If so, how did it go? I would love to hear your opinions and experiences!
