Tracking metrics tells you what happened, while on the other hand using data to make decisions tells you what to do next. Many brands collect dashboards full of numbers but don’t translate them into action. Real data usage connects behaviour to outcomes. Why do people drop off? What drives repeat purchase? Which products build long-term value? That’s where growth decisions start to become informed rather than reactive.

Brands like Allbirds use retention and LTV data to shape product, experience, and marketing choices, not just to review performance. At Suplex, we usually spend one to two weeks setting up analytics in a way that’s tied to actual business questions, not vanity metrics. If you want to start using data as a decision tool rather than a reporting tool, booking a call with our experts at Suplex is a good next step.

For D2C brands focused on growth, a handful of metrics matter far more than everything else. Conversion rate shows how well your store turns interest into revenue. Repeat purchase rate tells you whether customers actually like what they bought. Lifetime value reveals whether your business is compounding or constantly starting from zero. These three together give a much clearer picture of growth health than impressions or follower counts ever will.

Brands like Dollar Shave Club famously prioritised LTV over vanity metrics, which shaped how they invested in retention, pricing, and experience. At Suplex, we usually spend about a week helping brands decide which metrics deserve focus based on their model and stage. If you want to start tracking what genuinely drives growth, having a quick conversation with our experts at Suplex can help set that foundation.

Data analytics shows you what customers won’t tell you directly. It highlights where people hesitate, abandon, repeat actions, or get stuck in loops. When you combine behavioural data with funnel and event tracking, patterns start to emerge. You can see exactly which steps create friction and which ones move users forward smoothly.

Brands like Warby Parker use behavioural data to continuously refine key journeys such as product discovery, selection, and checkout. At Suplex, we usually spend one to two weeks analysing customer journeys to surface these hidden friction points. If you want to understand where your users are struggling and why, speaking with our experts at Suplex can help uncover what’s really holding conversion back.

Most brands don’t fail at collecting data. They fail at turning it into action. Teams end up with too many dashboards, too many tools, and no clear ownership of who is responsible for acting on what. When everything is tracked, nothing is prioritised, and insights quietly die in reports.

Companies like Peloton restructured analytics ownership so that data directly informed product and growth decisions rather than living in silos. At Suplex, we usually spend about a week building simple action frameworks that connect specific metrics to specific decisions. If you want to simplify your analytics and make it actually useful, having a conversation with our experts at Suplex can help set that up.

Conversion rate optimisation isn’t just about squeezing more sales out of the same traffic. At its core, it’s about reducing friction and increasing customer confidence. When people feel unsure, confused, or slightly uncomfortable at any step, they hesitate. CRO focuses on removing those moments so the experience feels natural, trustworthy, and easy.

Brands like Warby Parker optimise trust signals alongside conversion elements, because confidence is just as important as persuasion. At Suplex, we usually spend one to two weeks on CRO discovery to understand where users feel uncertain and why. If you want to optimise with real intent rather than surface tweaks, talking with our experts at Suplex is a good place to start.
