• use Keyword Planner to evaluate how the campaign might perform better on search partner sites
• segment the campaign’s data by network and evaluate its performance on search partner sites
• evaluate the campaign’s performance on search partner sites vs. display partner sites
• review the Overviews page to see the top searches on Google.com that caused your ads to display
