This is an interesting site, with a unique concept to keep users on their homepage for long enough. Jellyfish.com is an online search engine for online shoppers.

The unique concept I was talking about is a section called ‘Smack Savings’ on the homepage. It has a feature product with a discount % next to it. As you wait and watch, you will slowly see the % incrementing by 0.1%!

Hence spend more time on the homepage, and you can get a bargain buy. It also has a different and smart way of shops bidding for your purchase. More of that is explained here

Recently Microsoft bought Jellyfish.com not only to compete with other online shopping site, but also to capture a greater market share on online advertising.
