Open Google Analytics right now. How many metrics can you see? Fifty? A hundred? More?
Here's the problem: most of those numbers tell you nothing about whether your marketing is making money. They're interesting, sure. But interesting and useful aren't the same thing.
After working with businesses across industries, I've narrowed it down to seven metrics worth tracking. Everything else is noise until you've got these dialed in.
1. Customer acquisition cost (CAC)
This is the single most important number in your marketing. How much does it cost to get one paying customer?
The formula is simple: total marketing spend divided by number of new customers acquired in the same period.
If you spent Rs 1 lakh on marketing last month and got 20 new customers, your CAC is Rs 5,000.
Why it matters: if your average customer spends Rs 3,000 with you, and it costs Rs 5,000 to acquire them, you're losing money on every sale. No amount of "brand awareness" fixes that math.
Track this monthly. Break it down by channel if you can — your Google Ads CAC might be Rs 2,000 while your Instagram CAC is Rs 8,000. That tells you where to put your next rupee.
2. Customer lifetime value (LTV)
CAC tells you what you're spending. LTV tells you what you're earning.
Lifetime value is the total revenue a customer generates over their entire relationship with your business. A dental patient who visits twice a year for five years at Rs 3,000 per visit has an LTV of Rs 30,000.
The magic ratio is LTV:CAC. If your LTV is three times your CAC or higher, your marketing is working. Below that, you either need to reduce acquisition costs or increase how much each customer spends.
3. Conversion rate
Not website conversion rate — though that matters too. I mean the conversion rate at each stage of your funnel.
Ad impression to click: are people interested?
Click to landing page engagement: does the page deliver on the ad's promise?
Engagement to inquiry: is the call to action compelling?
Inquiry to sale: is your sales process working?
A 2% website conversion rate sounds low, but it might be fine if your traffic is highly qualified. A 10% rate sounds great, but not if those "conversions" are just newsletter signups that never buy.
Measure conversion at each step. The biggest drop-off tells you where to focus.
4. Return on ad spend (ROAS)
If you're running paid ads, ROAS is your scoreboard. Revenue generated from ads divided by ad spend.
A ROAS of 4 means every rupee you spent on ads brought back Rs 4 in revenue. For most businesses, a ROAS of 3-5x is healthy. Below 2x, you're probably losing money after accounting for product costs, overhead, and ad management fees.
Some industries run on thin ROAS margins because their margins are high (software, consulting). Others need 5x or higher because their margins are tight (retail, food).
Know your break-even ROAS. Then aim above it.
5. Organic traffic growth (month over month)
This one takes patience. Organic traffic from Google is the closest thing to "free leads" in digital marketing, but it builds slowly.
Track month-over-month organic traffic growth. If you're publishing content and doing SEO work, you should see steady increases after the first 3-4 months. Not dramatic jumps — more like 5-15% monthly growth.
If organic traffic is flat for three months despite consistent effort, something's wrong. Could be technical SEO issues, thin content, or targeting keywords that are too competitive.
The businesses that invest in organic traffic for a year tend to reach a point where marketing costs drop significantly because Google is sending them qualified visitors for free.
6. Lead response time
Not technically a marketing metric, but it sits at the intersection of marketing and sales, and it's where most businesses bleed money.
Measure how long it takes from when a lead submits a form or calls to when someone from your team responds. The data on this is pretty clear: leads contacted within the first hour are far more likely to convert than those contacted after 24 hours.
If your average response time is "sometime the next business day," you're handing leads to faster competitors. Set up alerts, automate initial responses, and make fast follow-up someone's explicit responsibility.
7. Revenue attribution by channel
Which marketing channel is actually generating revenue? Not leads — revenue.
This is harder to track than it sounds, especially for businesses with longer sales cycles. Someone might find you through Google, visit your Instagram, read a blog post, and finally call after seeing a retargeting ad. Which channel gets credit?
Don't overthink it. For most small businesses, "first touch" attribution works fine — credit the channel that brought them in initially. Use UTM parameters on your links, ask "how did you hear about us?" in your forms, and review monthly.
The goal isn't perfect attribution. It's knowing, roughly, that "Google Ads brings us most of our paying customers" or "Instagram brings followers but not buyers." That's enough to make good budget decisions.
What to ignore (for now)
Social media followers, post impressions, email open rates, page views, bounce rate, time on site, domain authority.
These metrics have their uses. But none of them directly answer the question: "Is our marketing making money?" Until you've got the seven core metrics tracked and healthy, these secondary numbers are distractions.
Set up a simple dashboard — even a spreadsheet works — with these seven numbers updated weekly or monthly. Review it in 15 minutes. Make one decision based on what you see. That's more strategic thinking than most businesses do in a quarter.
