Siva, the reward is award for using mylot search. So far I had received 4 times reward for using mylot search. Twice 15 cents and once 16 and 17 cents. Actually I am using mylot search for collecting more details regarding my final year project. its more useful and also it gives you money at the end. Even though I am using the search in regular manner and for useful purpose only, once I received warning message, so be careful and don't try to play in the search engine for earning money beause there is an instrction in FAQ which states that they will cancel the account without any intimation. Please go through those instruction also as quoted by previos responders.

The only way to earn rewards is just by performing normal search. The rewards will come "randomly" (even I believe there are some sort of algorithms that determine when the rewards will come). It is already explained at the FAQ. So, try to enrich your knowledge about myLot by reading FAQ and guidelines. It will help you a lot :). And here is a discussion that may help you to perform search with myLot more conveniently.. :) www.mylot.com/w/discussions/2479267.aspx

I am not abusing the use of myLot search engine. It maybe the reason why I haven't received any rewards yet. It's not that easy to guess when the search is already abusive or not. How about if at a certain point in time, I really need to search for so many unfamiliar words or topics? To make it safe, I'll no longer use myLot search engine because everytime I'm using it, I always fear if I am already abusing it or not.
