Smart Bidding is a set of conversion-based bid strategies — Target cost per acquisition (tCPA), Target return on ad spend (tROAS) and Enhanced cost per click (eCPC) — that uses advanced machine learning to help you tailor the right bid to each and every auction.
It factors in a wide range of auction-time signals including browser, device, location, time, remarketing list, language, and operating system to capture the unique context of every search.
