The document compares Google Adwords and Demand Side Platforms (DSPs) for display advertising. It finds that while both are buying platforms, DSPs were designed for display ads and have several advantages over Adwords. DSPs have greater reach through access to billions of daily impressions across many supply-side platforms. They also have more frequent, granular reporting available in real-time for more effective optimization. DSPs also have more advanced targeting options through real-time bidding technology and access to various data sources. While both have self-serve options, DSPs are generally better suited than Adwords for large-scale digital display advertising.
