The tool communicates with the API of Google Adwords - their online advertising product. Two screens positioned next to the speakers' stage display a ranking of the 10 most (and least) popular words according to the data provided by Google. These words are typed live as the speakers present their talks and are displayed using elements that resemble the stock market.
After the lectures, the Optimization Report is presented, containing an overview of the results, title suggestions for each lecture and a generated advert text to promote the Exhibition The Gig is Up.
