Use the Ad Group Optimisation Guidelines page to define optimisation guidelines for the selected ad group (if optimisation is available for your account). The ad group optimisation guideline values you set for the ad group will override the default optimisation guideline values you set for the campaign.
Understanding Ad Group Optimisation Guidelines
To turn on campaign optimisation, first define your campaign optimisation guidelines. The campaign optimisation guideline values you set apply to the campaign and to all ad groups in that campaign. If you have a different optimisation strategy for any ad group in a campaign, use the ad group optimisation guidelines to set custom values for that ad group.
