All of these matters put together make the points, that is solely decided by the concerned editor. The more it satisfies the above said criteria, the more it scores high, the less, it goes less. It has to be noted, none of the above said features alone can score high.
More or less, what I have noticed, 150-200 points have been given to the best articles written on this site so far.
Go by the standards that the site has set for the articles and their quality. The points will depend upon the useful information contained in the articles and the originality. Ensuring correct grammar and originality of the contribution will fetch you more points. Please note that the decision with respect to the points and the cash credit awarded to a particular article would be solely dependent upon the concerned editor. Ideally, a good article with original content and useful information with around 1000 to 1200 words should fetch you around 100 points and Rs.100 cash credits. However, please note that this can be a standard case. There are many points considered while allotting points to an article and those together will form the basis for the total points you gain.
Live....and Let Live!
