Microsoft today launched SearchPerks, which gives users points when they use msn live search, and then the points can be redeemed for all sorts of rewards.

The new CashBack programme encourages people to use Live Search,  and they believe it will work in terms of increasing market share of online search.

To participate the SearchPerks, you have to download a special browser add-on, and you must use Internet Explorer. So, Microsoft is trying to kill three birds with one stone:

1. To get more Live Search users
2. To get more IE users
3. To have a better understanding of what people are searching for
