Firstly I would say that to earn from mouthshut.com you need to have lots of patience because they don’t credit you very easy they take more than 48 hours to check your reviews and after checking they will decide whether your review meets their quality terms and then they will think to approve or to disapprove.
So during this procedure many people gets disheartened and they stop giving their reviews, so this is the first mistake usually people do.
As I said, you need to have lots of patience
Second thing to be on MouthShut.com, always give genuine reviews, I prefer giving reviews only to the product which I bought.
So don’t give reviews on any product, always be genuine.
Don’t mess up with like and dislike
If you like the product than all of your description should be in positive, I hope you are getting my point.
Lastly never loose hope
You may not earn in early days but as time passes you will start earning to the genuine reviews.
And also always follow the terms and conditions, as to avoid disappointment.
