The document discusses 5 ways that AI can be used for online advertising. 1) AI requires good quality data to be effective, while garbage data can undermine results. 2) AI can either optimize campaigns around one single goal like ROAS, or segment campaigns based on product attributes. 3) AI can help activate "long tail" products with little data by gradually increasing their bids. 4) "Turbo campaigns" can use AI to always outbid competitors to dominate product categories. 5) Price differences compared to competitors strongly impact conversions, so bids may need adjustment based on competitors' pricing.
