Being able to defend a budget decision shows critical thinking and communication skills. Employers want associates who can justify spend based on strategy, not just blindly chase high ROAS.
Acknowledge the manager’s concern, then walk through your reasoning: the role of the campaign in the funnel, other hidden benefits (like brand awareness or data collection), and any testing plans. Offer to adjust only if data suggests a better alternative.
Start by acknowledging the manager's concern directly and without defensiveness, then pivot quickly to the reasoning behind the decision. Explain that a 1.2x ROAS on a single ad set does not automatically mean failure, especially if that ad set was serving a specific objective like top-of-funnel awareness, retargeting, or gathering conversion data for a new audience. Say plainly that you allocated 60% because the campaign was designed as a testing phase, and the primary goal was not immediate profit but learning which creative, copy, or audience segment could scale profitably later. Mention any secondary benefits you observed, such as increased page engagement, lower cost per click, or a stronger pixel signal that improved performance on other ad sets. Then, present your plan: you would review the data weekly, set a clear threshold for when to cut losses, and propose shifting budget to a better-performing set if the numbers justified it. Close by inviting the manager to look at the full dashboard with you, showing you are transparent and open to course correction. Keep your tone composed, and use a confident but respectful register, mixing English with a natural Taglish phrase if comfortable, to show you are not intimidated by the question.
A typical Filipino response might be to over-apologize: 'Sorry po, Sir/Ma'am, hindi ko po na-check nang mabuti.' Instead, confidently present the strategic rationale behind the allocation and offer data to back it up.
Situation
While handling paid social for a mid-sized e-commerce client at my previous agency, I allocated PHP 12,000 of a PHP 20,000 monthly budget to a single ad set targeting lookalike audiences.
Task
The client noticed the concentration and demanded to know why so much budget was on an ad set with low ROAS.
Action
I responded calmly with data: that ad set had a 1.2x ROAS but it was our top-of-funnel prospecting campaign that introduced 70% of all new site visitors, while our retargeting ads (with higher ROAS) depended on that traffic. I also presented the blended ROAS of the entire funnel, which was 2.8x. I explained that cutting the prospecting budget would shrink future retargeting pools and harm overall performance. I proposed to keep the allocation for another month while A/B testing lower-cost prospecting creatives.
Result
The client accepted the explanation and agreed to the test. The next month, we reduced CPA on that ad set by 15% through creative testing while still feeding the funnel.
Always connect spend decisions to the full customer journey, not just isolated ad sets.
