PPC Metrics Your CFO Cares About: How to Report Them

You’re putting the finishing touches on a monthly PPC report, proud of the progress you’ve made. You highlight an A/B test that lowered CPA and a new Meta campaign driving marketing qualified leads. But when you present it to leadership, the response is, “How does this actually grow revenue?”

Knowing your audience is a core marketing principle, and it applies just as much to reporting. A report built for a marketing director, who lives in the campaign details, will look very different from one designed for a C-level executive. When senior leadership reviews your work, you need to consider what they are held accountable for. A CFO answers to shareholders or venture capital firms, but their ultimate priority is increasing revenue. If your report doesn’t clearly answer whether PPC investments are profitable, you’re setting yourself up for tough questions.

This article breaks down the PPC metrics your CFO actually cares about and how to present them effectively.

First, Nail Your Tracking

Before launching any campaigns or building reports, ensure proper conversion tracking is set up on your website to measure key actions in your ad and analytics platforms. If you’re not confident in your data measurement, you can’t trust the numbers in your reports.

Align on Shared Goals

Before writing your first report, talk to key stakeholders about internal revenue goals and where PPC fits. For example, a business might aim to grow revenue by 10% or increase its customer base by 20%. When choosing metrics and framing them, think about how measurement ties to those shared goals. You might show not only that Meta saw a 10% increase in conversions, but that it was the largest contributor to last month’s growth target. Consider including a section with a graph of total new accounts or revenue versus plan.

CPA, But Define the Conversion

Cost Per Acquisition (CPA) is a foundational PPC metric. However, a common question is, “What exactly counts as a conversion?” Microconversions like form fills or asset downloads can be useful for optimization, but for executives, you must be crystal clear about what you’re reporting. Ideally, tie CPA as closely as possible to a customer. For long-cycle businesses, reporting actual customers monthly may not be feasible, but you can report on sales qualified leads. If you have proper CRM tracking, you can show CPAs for customer acquisition over a longer period. For example, if your average sale takes 90 days, present a 90-day view with costs and CPAs broken down by marketing qualified leads, sales qualified leads, and final sales.

Customer Acquisition Cost

Customer Acquisition Cost (CAC) is a more comprehensive metric: total sales and marketing expenses divided by the number of customers acquired in the same period. CAC can be reported overall and at the channel level if your CRM tracks customer source. Report on trends over time to show how campaign mixes perform and highlight seasonal patterns.

Return on Ad Spend

ROAS is easier to attribute in some accounts (like ecommerce) than others (like B2B with long sales cycles), but it directly points to return on investment from PPC. If revenue values are measured correctly, ROAS answers, “How much did we make from this campaign?” Be ready to explain how ROAS is calculated, including whether it accounts for shipping and taxes. Report ROAS at a blended level and more granularly where specific efforts deserve attention.

Lifetime Value

Acquiring new customers is great, but what if they buy once and never return? Lifetime Value (LTV) shows which channels and campaigns drive the most valuable customers, not just the most customers. For ecommerce, look at total revenue per person over time. For SaaS, consider total subscription cost. For industrial equipment, factor in product purchases and ongoing servicing.

Incremental Growth

When testing new channels or offers, the key justification for funding is proof of incremental growth , new revenue that wouldn’t have come from existing efforts. Showing new customer counts and revenue from tests helps secure future budget. In-platform tracking can be tricky, as a new Google campaign might claim conversions also influenced by Meta. Use a Media Mix Modeling (MMM) tool for a broader view, or run incrementality tests by isolating campaigns to specific geographies or comparing time periods. Be transparent about your testing methodology, lead with results, and put technical details in an appendix.

Anticipate the Questions

When including metrics relevant to your stakeholders, think proactively about what questions will come. If conversions are down, you’ll be asked why. Build rapport by being transparent about negative performance and offering reasonable explanations. For instance, compare seasonal performance to last year or note a technical issue with a form. Include brief bullet points in the report addressing these concerns upfront, and be ready to dive deeper if asked.

Start Building Better Reports

Think through the metrics above and how to present them to your CFO and executives. Reflect on your previous reporting and any pain points in reaching shared understanding. Build on solid tracking to highlight numbers that resonate with those holding the purse strings. Be open to questions and additional data requests, and keep refining your reports to meet stakeholders where they are.
