Social networking website Twitter allowed advertising on its pages for the first time. Today millions of the user will see the first paid advertisement on this website.

The model is inspired by the Google advertising format. It will buy ads to appear in its search results.

As per sources, the website is also in a process to introduce ads in the main twitter feeds-based user feedbacks. However, no formal information was received from Twitter.

Nevertheless, the website is currently very careful in starting up the service as it does not want to upset its users by overloading the site with advertisement.

Biz Stone, Twitter's co-founder insisted on a slow and thoughtful approach to monetization, on a blog post. He added that the brands would be allowed to place short messages at the top of the list of the search results, so that when the users look for some particular information or product the ad will be visible to them.
