AI search engine Perplexity officially launched its advertising program in the US market this week, creating a new model for search advertising. This highly anticipated AI company has successfully attracted several advertising giants, including Indeed, Whole Foods, Universal McCann, and PMG. Unlike traditional search advertising, Perplexity has innovated an advertising format that integrates into the AI interaction process. Advertisers can naturally incorporate questions in relevant contexts, such as how to use Indeed to optimize job search strategies.
