Earning online is not easy. It takes time. Very hard work is needed. You will have to sit and work. Without consecutive work it is not at all possible for you to earn online. If you really want to earn through writing and posting you will have to work not less than four to six hours daily.
Interaction is very important in this regard. Interaction means to write comments and to like the post of the members on this web site. Comments must valid and as per TOS of the website you are writing. For example on Chillkey you have to write a comment of 80 characters. Do not try to fill it with dots or any other unfair mean. This is considered as spamming. Similarly write the post not less than 700 or 750 words. Filling it through unfair means like dots or repeating words will be considered as spamming and your account can be deleted by the administration.
Be optimistic, no abusive language, no copy past at all.
