What Metrics Do We Use to Measure the Effectiveness of Our Marketing Campaigns?

“Half the money I spend on advertising is wasted; the trouble is, I don’t know which half.” That quote, often attributed to John Wanamaker, still haunts SaaS CEOs today. But in a world of real-time dashboards, AI-driven attribution, and precision targeting, there’s no excuse for flying blind.

For SaaS companies, marketing isn’t just about brand awareness—it’s about measurable growth. Whether you’re optimizing CAC to boost valuation multiples or evaluating campaign ROI ahead of a strategic exit, the right metrics are your compass. Drawing on research from elite MBA programs, insights from SaaS leaders like David Skok and Jason Lemkin, and data from sources like McKinsey and SaaS Capital, this article breaks down the essential KPIs every SaaS CEO should track to measure marketing effectiveness.

1. Customer Acquisition Cost (CAC)

Why it matters: CAC is the cornerstone of SaaS marketing efficiency. It tells you how much you’re spending to acquire each new customer. According to SaaS Capital’s 2023 survey, the median CAC payback period for B2B SaaS companies is 16 months—anything longer can drag down your valuation.

How to calculate:

• CAC = Total Sales & Marketing Spend / Number of New Customers Acquired

Break this down by channel (e.g., paid search, content, outbound) to identify what’s working. Tools like HubSpot, Salesforce, and attribution platforms like Dreamdata can help you track this granularly.

2. Customer Lifetime Value (CLTV)

Why it matters: CLTV helps you understand the long-term value of a customer. When paired with CAC, it gives you the LTV:CAC ratio—a key metric for investors and acquirers. A healthy SaaS business typically aims for a ratio of 3:1 or higher.

How to calculate:

• CLTV = (Average Revenue per Account × Gross Margin %) / Churn Rate

As explored in SaaS Key Performance Metrics (KPIs) and Valuation Multiples, improving CLTV through upsells, renewals, and product stickiness can significantly increase your company’s valuation multiple.

3. Marketing Qualified Leads (MQLs) and Sales Qualified Leads (SQLs)

Why it matters: Not all leads are created equal. MQLs and SQLs help you measure the quality—not just the quantity—of your lead generation efforts. According to Wharton’s marketing analytics curriculum, tracking lead conversion rates across the funnel is essential for optimizing spend.

Key metrics to track:

• MQL to SQL Conversion Rate
• SQL to Opportunity Conversion Rate
• Opportunity to Closed-Won Rate

These metrics help you identify bottlenecks and align marketing with sales. If MQLs are high but conversions are low, your targeting or messaging may be off.

4. Multi-Touch Attribution and Campaign ROI

Why it matters: In a multi-channel world, last-click attribution is obsolete. Stanford’s MBA program emphasizes the importance of multi-touch attribution models to understand how different touchpoints contribute to conversions.

Key tools: Use platforms like Bizible, Attribution App, or Google Analytics 4 to assign weighted credit across email, paid ads, webinars, and content. Then calculate:

• Campaign ROI = (Revenue Attributed to Campaign – Campaign Cost) / Campaign Cost

Campaign ROI helps you justify budget allocation and scale what works. For example, if a $50K webinar series drives $300K in ARR, that’s a 5x return—worth replicating.

5. Website and Funnel Conversion Rates

Why it matters: Your website is your storefront. If traffic isn’t converting, you’re leaking revenue. According to McKinsey’s 2023 digital growth report, top-performing SaaS firms obsess over conversion rate optimization (CRO).

Metrics to monitor:

• Landing Page Conversion Rate
• Free Trial to Paid Conversion Rate
• Demo Request to Close Rate

As discussed in Conversion Rate Optimization (CRO), even a 1% lift in conversion can translate into millions in ARR over time.

6. Net Promoter Score (NPS) and Customer Satisfaction (CSAT)

Why it matters: Marketing doesn’t end at acquisition. Retention and advocacy are critical. NPS and CSAT are leading indicators of customer loyalty and word-of-mouth growth—both of which reduce CAC over time.

Use cases: Track NPS by cohort and correlate it with upsell rates, churn, and referral volume. High NPS often signals product-market fit and can be a powerful asset during M&A discussions.

7. Pipeline Velocity and Marketing-Sourced Revenue

Why it matters: Speed matters. Pipeline velocity measures how quickly leads move through your funnel. Marketing-sourced revenue shows how much of your ARR is directly attributable to marketing efforts.

Pipeline Velocity Formula:

• Pipeline Velocity = (# of SQLs × Win Rate × Deal Size) / Sales Cycle Length

Faster velocity means quicker revenue realization and better cash flow—key factors in exit business planning strategy and valuation modeling.

8. Channel Performance and CAC Payback by Segment

Why it matters: Not all channels or customer segments are equally profitable. Segmenting CAC and payback by industry, company size, or geography helps you double down on high-ROI areas.

Example: If SMBs convert faster but churn more, while mid-market clients have longer sales cycles but higher CLTV, your marketing mix should reflect that balance.

9. Brand Awareness and Share of Voice (SOV)

Why it matters: While harder to quantify, brand equity drives long-term growth. Harvard Business School’s case studies on SaaS scaling emphasize the role of brand in reducing CAC and increasing pricing power.

Metrics to consider:

• Direct Traffic Growth
• Branded Search Volume
• Share of Voice in Industry Publications or Social Media

Use tools like SEMrush, Brandwatch, or Google Trends to benchmark your visibility against competitors.

10. Marketing Efficiency Ratio (MER)

Why it matters: MER is a high-level metric that shows how efficiently your marketing spend translates into revenue. It’s especially useful for board reporting and M&A prep.

Formula:

• MER = Gross Revenue / Marketing Spend

According to PitchBook, SaaS companies with MERs above 5x tend to command higher valuation multiples, especially in capital-efficient growth environments.

Bringing It All Together: A SaaS Marketing KPI Dashboard

Inspired by Stanford’s innovation metrics framework, here’s a simplified dashboard you can implement:

• Top Funnel: Website Traffic, MQLs, CAC by Channel
• Mid Funnel: MQL to SQL Rate, SQL to Opportunity Rate, Pipeline Velocity
• Bottom Funnel: CAC Payback Period, CLTV, LTV:CAC Ratio
• Post-Sale: NPS, CSAT, Expansion Revenue
• Strategic: MER, Marketing-Sourced Revenue, Brand SOV

Advisors like iMerge use these metrics during due diligence to assess marketing scalability and acquisition readiness. If your dashboard shows strong CAC efficiency, high CLTV, and scalable channels, you’re in a strong position—whether you’re raising capital or exploring a sale.

Conclusion

Marketing effectiveness in SaaS isn’t about vanity metrics—it’s about measurable, scalable growth. By tracking the right KPIs, you can optimize spend, align with sales, and build a marketing engine that drives enterprise value. Whether you’re preparing for a strategic exit or simply aiming to outperform your competitors, these metrics are your roadmap.
