Twitter plans to adopt Google's very successful Ad Model for its own website.

According to All Things Digital, Twitter will let advertisers sign up to have their ads show up as tiny 140-word posts when users search through Twitter or through other search engines that use its API.

A search for, say, “laptop,” may generate an ad for Dell. The ads will only show up in search results, which means users who don’t search for something won’t see them in their regular Twitterstreams…. The services will have the option of displaying the ads, and Twitter will share revenue with those that do, according to the report.

The ads will also use the Twitter format–140 or fewer characters–and will be distributed via the third-party software and services that use Twitter’s API. The services will have the option of displaying the ads, and Twitter will share revenue with those that do.

The popular micro-blogging site will work with ad agencies and buyers to seed the program, but has plan to become like Google's self-serving advertising model.
