How We Measure Success

More people are buying. They're buying more. And they keep coming back.

Retention and CRO are about getting the most out of every customer you’ve already paid for. That’s why we track the four metrics that show whether we’re succeeding:

CAC:LTV.

The ratio between what it costs to acquire a new customer and what that customer is worth over time. The higher the LTV relative to the CAC, the more you can invest in growth and still make a profit.

CAC: Cost per New Customer
400 DKK
LTV: Value per Customer Over Time
1,200 DKK

CAC:LTV = 1:3

Illustrative example. The actual target depends on your margins and is determined in Phase 2.

Conversion rate.

How many of your visitors end up making a purchase. Small improvements here make every advertising krone go further.

Before1.8%After2.4%of the visitors who make a purchase

Illustrative example.

AOV.

The average order value. Bundles, special offers, and a better shopping cart encourage customers to buy more per order.

Before520 DKKAfter610 DKKper order

Illustrative example.

Repeat customer rate.

The percentage of orders from customers who have purchased before. It shows whether your sales funnels, newsletters, and customer experience are effective.

What kinds of companies do you work with?

We work with established e-commerce and consumer brands—typically in the fashion, lifestyle, home, beauty, and health sectors—that generate at least 300,000 DKK in monthly revenue (excluding VAT) and are poised for profitable growth, both domestically and internationally.

What happens during a growth analysis?

One of our partners will review your numbers before the meeting. During the meeting, you’ll receive a concrete assessment of your biggest bottleneck to growth and a recommended action plan. There’s no obligation, and you’ll gain valuable insights regardless of whether we end up working together.

Why choose Growbix over other agencies?

We come from the brand side ourselves and still run our own consumer brand, TRIVE, so we understand the entire business—not just marketing. Our team is led by senior professionals, and we bring together advertising, Klaviyo, Shopify, CRO, and business consulting under one partner. We focus on contribution margin and profitable growth, but we also know what it takes to build a brand. And we’re selective about our clients. That’s why many of our partnerships last 3–6 years.

How much does a partnership cost?

The price depends on your goals, the scope, complexity, and budget of your project, as well as the services and number of markets covered by the partnership. After the growth analysis, you’ll receive a specific quote before you commit to anything.

Is there a commitment?

As a general rule, we have a 1-month rolling commitment. For certain partnerships, there may be a 3-month rolling commitment, but this is always agreed upon in advance.

Do you help companies enter new markets?

Yes. We have active clients in 30 markets and assist with everything from market analysis and localization to marketing in each country.

How do you measure your results?

We focus on contribution margin, MER , and brand awareness, supplemented by CAC, LTV, conversion rate, and AOV. All figures are consolidated into a single dashboard so you see the same data we do.

What platforms do you work with?

We work across the entire funnel: paid social on Meta, TikTok, YouTube, Pinterest, and Snapchat; paid search and Shopping on Google; email and newsletters in Klaviyo; and online stores on Shopify. The channels we use depend on your brand, your customers, and your markets.
