How do I manage my bids in Express campaigns?
The bids you set per target will serve as benchmarks for what you actually bid, so it's important to manually optimize your bids. For example, if a target has a high conversion rate, you should increase its bid to raise ROI.
The Express algorithm predicts the margin your bid should be raised or lowered, but will only adjust your bid lower. If a higher margin is calculated as optimal, your target will not be eligible for the impression.Learn more about channels.
