While it may be possible to serve ads with a very low bid, your campaign may not enter or win as many auctions and your ads may not have any impressions.
What you can do
- Confirm your campaign’s optimization strategy is aligned to your business goals.
For example, if your goal is to drive as many conversions as possible within a set budget, use the Maximize conversions strategy. - With your set optimization goal, consider whether your automated bidding target is achievable based on historical performance. If your target is too low (CPA) or high (ROAS), your campaign may not be able to perform at that level and stops serving.
For example, if you’re using target CPA bidding and your target CPA is significantly below your historical average CPA for that conversion goal, your target CPA may not be attainable while maintaining reasonable levels of traffic, and you should consider raising your target.
