To boost performance, Absa and agency partner Maxus began an intensive programme of account optimisation and took advantage of a new advanced audience and bidding strategy, Target CPA bidding (tCPA), for some of their top campaigns. An AdWords Smart Bidding strategy, tCPA sets bids to help get as many conversions as possible at the target cost per acquisition set by the advertiser. It uses advanced machine learning to automatically optimise and tailor bids for each and every auction.

Using historical information about Absa’s campaigns and evaluating contextual signals, tCPA bidding automatically found an optimal bid for every Absa ad whenever it was eligible to appear. AdWords set these bids to achieve an average CPA equal to the target across all ad groups and campaigns.
