Social Networking and Micro blogging site twitter charges a whopping $500,000 to feature a single banner advertisement for a day.

CEO of uSocial said that although the amount might be huge the investors can get more worth than their actual investment.

While $500,000 may seem like a large amount to invest in one banner for one day, we believe that the investment will be more than worth it—he said.

One of Twitter's Co-founders Evan Williams said that they are working hard to make their advertisers money worth.

"We will charge brands but they will only pay if we offer them something worth paying for and the site is working well for them"—he said.

We can't force them to pay, and some of them will refuse. However, we need to improve our offering before we do this"—he added.
