Key performance metrics to compare agencies: ROI, CAC, LTV, time-to-value

Begin with a shared KPI playbook that defines ROI, CAC, LTV, and time-to-value for all campaigns. Use a single source of truth so comparisons stay accurate as demand and leads fluctuate. Define successful metrics by net revenue generated per dollar spent and set target thresholds by channel and region. This creates a successful, actionable basis for measuring agency performance.

ROI should be the north star for prioritizing actions. Compute ROI as net revenue minus spend, normalized by the attribution window and currency, then compare agencies on the margin each dollar invested yields. Align attribution across touchpoints to ensure apples-to-apples results, and regularly review the data to detect drift. This approach helps teams connect creative thinking with measurable outcomes and ensures the message stays consistent across channels, so campaigns scale efficiently.

CAC requires disciplined tracking: CAC equals total marketing and sales costs divided by new customers acquired in the period. Include onboarding, training, and platform fees to avoid underestimating cost. Compare CAC across channels and campaigns; aim for a LTV/CAC ratio of at least 3:1 to indicate sustainable growth. A known, regular focus on CAC helps you identify which agency delivers high-quality leads rather than just volume, making it invaluable for budget planning and prioritization. Keep the data accessible in a home analytics repository to prevent drift between platforms and teams.

LTV anchors profitability by showing how much value a customer generates over their lifetime. Calculate LTV using average revenue per customer, gross margin, and expected retention; adjust for churn and discount rate. Compare LTV across agencies to spot long-term winners, and prefer partners that deliver higher lifetime value without inflating acquisition costs. When LTV/CAC improves, you gain confidence to scale and invest in channels that sustain demand growth and steady lead flow.

Time-to-value measures how quickly campaigns produce first meaningful results after kickoff. Define the initial action (qualified lead, demo, or trial signup) and track days to result. Shorter time-to-value reduces risk and improves cash flow, usually signaling efficient onboarding, clear briefs, and fast feedback loops. Use standardized definitions to compare agencies between stages of execution and across channels, so you can act on early signals and adjust tactics promptly.

To compare agencies effectively, connect metrics to business outcomes: pipeline velocity, growing demand, and increasing leads. Build an accessible dashboard that updates regularly and supports rapid checks. Schedule a clinic-style cadence of reviews–weekly checks for current performance and monthly deep-dives for strategy alignment. The message should be original and precise, reflecting your home goals while drawing on each agency’s playbook. This fosters trust and helps managers see concrete differences in approaches and results. A thoughtful mindset thinking through constraints, including regulatory factors like visa considerations, keeps plans realistic and actionable.

Practical steps to implement: (1) align on definitions for ROI, CAC, LTV, and time-to-value; (2) standardize attribution and data sources; (3) set target ratios (for example, LTV/CAC ≥ 3:1) and time-to-value benchmarks by campaign type; (4) run quarterly comparisons using a consistent scorecard that includes qualitative signals such as creativity, consistency of message, and ability to adapt to constraints; (5) use regular, collaborative sessions where the creator or agency lead shares original thinking and concrete next steps. This structured, connected workflow makes it easier to identify the most successful partner for growing demand and turning leads into loyal customers.
