What's an example of a campaign that fell short of its target goal?

The correct answer is the search campaign with an expected increase in return on ad spend (ROAS) of $50.12 and an actual ROAS of $10 because the actual performance ($10) is significantly lower than the expected target ($50.12). This indicates the campaign fell short of its goal. The other options describe campaigns that either met or exceeded their goals: An email remarketing campaign with an actual lift of 12% exceeded its expected lift of 5%. A video campaign with an actual lift of 5% met its expected lift of 5%. A display campaign with an actual lift of 20% exceeded its expected lift of 10%.
