A campaign with the lowest cost-per-click(CPC)will always drive the highest ROI.

The correct answer is False.While a low cost-per-click(CPC)can contribute to a higher return on investment(ROI),itisnot the sole determinant of campaign success.ROI is influenced by various factors beyond CPC,such as conversion rate,customer lifetime value,and overall campaign performance.A campaign with a low CPC may attract clicks at a lower cost,but if those clicks do not convert into valuable actions,such as leads or sales,the ROI may still below.Additionally,focusing solely on minimizing CPC may result in sacrificing other critical aspects of campaign effectiveness,such as targeting precision or ad quality,which can ultimately impact ROI negatively.Therefore,while CPC is an important metric to monitor,it should be considered in conjunction with other key performance indicators(KPIs)to assess the overall effectiveness and ROI of a campaign accurately.
