Coming soon: Simplified keyword states and quality-based minimum bids
In the coming weeks, your keywords will no longer be evaluated as normal, in trial, on hold, or disabled. Instead, your keywords will either be active or inactive, depending on their quality and maximum CPC. Each keyword will be assigned a minimum bid based on its quality. As long as its maximum CPC meets this quality-based minimum bid, your keyword will remain active and trigger ads. Learn more.
