The document discusses account based advertising (ABA) and provides tips for making it an effective marketing strategy. It summarizes Charlie Liang's presentation on ABA, including how ABA works by targeting specific accounts through multiple filtering layers. Some key benefits of ABA are more effective spending, better segmentation, and crisper messaging. However, ABA is more expensive than retargeting. The tips provided to make ABA effective include having a clear end goal, combining it with other tactics, only using it on top tier accounts, measuring results at the account level, keeping campaigns simple, and extensively testing strategies. An example ABA campaign integration is described and results from Engagio's ABA efforts are shared.
