Question: Based on the data below, which is the most effective advertising campaign?
- Campaign 1 because it has a greater return
- Campaign 1 because it drove more leads
- Campaign 2 because it has a greater return
- Campaign 2 because it drove more leads
or
- Campaign 1 because it drove more leads
- Campaign 1 because it has a lower lifetime value
- Campaign 2 because it has a greater return
- Campaign 2 because it has a higher CPA
Explanation
The provided answer key is internally inconsistent because it marks two different campaigns as correct while the campaign data itself is not shown. In HubSpot terminology, this type of comparison should be decided by return, commonly evaluated with ROAS, because it measures revenue generated for each advertising dollar spent. A campaign that drives more leads is not automatically stronger if those leads produce weaker return. A higher CPA is also not a sign of better performance because it means paying more for each acquisition. The reliable takeaway is that the most effective campaign is the one with the greater return, not simply the one with more leads or a higher CPA. HubSpot Blog+2HubSpot Knowledge Base+2
Why the other options are incorrect

Campaign 2 because it drove more leads Lead volume alone does not determine effectiveness when return is the deciding performance measure. HubSpot Blog+1
Campaign 1 because it has a lower lifetime value Lower lifetime value weakens business impact, so it does not support choosing a stronger campaign. HubSpot Knowledge Base+1
Campaign 2 because it has a higher CPA A higher CPA means less efficient acquisition cost, so it is not a reason to call a campaign more effective. HubSpot Blog
