How to Measure Marketing ROI: The Metrics Every Business Owner Should Track (Not Just Likes)
Treva Team
Published by Treva Digital Agency
Likes and reach are vanity metrics, they feel good to report but rarely tell you whether marketing is making your business more money. Revenue attribution is reality. This guide explains the six KPIs Treva tracks for every client, ROAS, CAC, LTV, funnel conversion rate, branded search volume, and organic session growth, and why each one matters for understanding true marketing performance. Quick answer: track ROAS (return on ad spend), CAC (customer acquisition cost), and conversion rate before any other metric.
1. ROAS (Return on Ad Spend)
ROAS measures revenue generated for every rupee spent on advertising, a ROAS of 4 means ₹4 in revenue for every ₹1 spent. This is the most direct measure of whether your paid campaigns are profitable. ROAS targets vary significantly by industry and margin structure, a high-margin service business can be profitable at a lower ROAS than a low-margin e-commerce product, so benchmarks should be set against your specific business economics, not generic industry averages.
2. CAC (Customer Acquisition Cost)
CAC is the total cost to acquire one paying customer, including ad spend and often a portion of marketing management costs, divided by the number of new customers acquired in that period. CAC matters because it must be compared against the value that customer brings (see LTV below). A campaign can have an impressive cost-per-click and still be unprofitable if CAC exceeds what a customer is worth.
3. LTV (Customer Lifetime Value)
LTV estimates the total revenue (or profit) a customer generates over their entire relationship with your business, not just their first purchase. The relationship between CAC and LTV is one of the most important numbers in a business: if CAC exceeds LTV, you lose money on every customer regardless of how efficient your campaigns look on the surface. A healthy LTV:CAC ratio is typically at least 3:1.
4. Funnel Conversion Rate
This tracks the percentage of people who complete each step of your customer journey, website visitors who become leads, leads who become customers, and so on. Tracking conversion rate at each funnel stage (rather than just an overall number) helps identify exactly where potential customers are dropping off, whether that is the ad itself, the landing page, or the sales follow-up process.
5. Branded Search Volume
This tracks how many people search directly for your brand name (or close variations) over time. Growth in branded search volume is one of the clearest signals that brand awareness and content marketing efforts are working, people who saw your content or ads elsewhere are now actively seeking out your business by name, a strong indicator of growing trust and recall.
6. Organic Session Growth
This tracks growth in website visits coming from unpaid sources, primarily organic search (SEO) but also direct visits and organic social referrals. Sustained organic session growth indicates that your SEO and content investments are compounding, generating traffic that does not require ongoing ad spend to maintain, a crucial long-term efficiency metric alongside paid performance.

Frequently Asked Questions
Which of these six metrics matters most if I can only track one?
If you can only reliably track one metric, track conversion rate from lead to customer combined with rough CAC, this combination tells you whether the leads your marketing generates are actually becoming paying customers at a sustainable cost, which is the foundation everything else builds on.
How do I track these metrics without a data team?
A CRM that captures lead source and deal outcomes (like Treva CRM) combined with your ad platform's built-in reporting and Google Analytics covers most of these metrics for small businesses. The key is consistency, tracking the same definitions over time, rather than sophistication of tooling.
What is a good LTV:CAC ratio?
A commonly cited healthy benchmark is 3:1 or higher, meaning a customer is worth at least three times what it costs to acquire them. Ratios below 1:1 mean you lose money on every customer. Ratios significantly above 5:1 can sometimes indicate you are under-investing in growth relative to your margins.
Why doesn't Treva report on likes and reach as primary metrics?
Likes and reach can provide useful directional signals for content strategy, but they do not directly indicate revenue impact. Treva's standard reporting leads with the revenue-connected metrics in this guide, with engagement metrics included as supporting context rather than headline results.
