Why CRO Matters for E-Commerce
Conversion rate optimisation (CRO) is the process of turning more of your existing website visitors into paying customers. You can spend thousands on Meta, TikTok, or Google ads, but if your site doesn’t convert, you’re leaving money on the table. At Stacks, CRO is how we make every euro of ad spend work harder — reducing wasted budget and increasing profitability.
Why it’s worth the investment:
- Compounding Returns: A conversion rate lift improves the economics of every channel at once — paid, email, and organic.
- Customer Trust: Online shoppers are cautious. If your site doesn’t feel credible, they won’t buy — whatever the product.
- Competition: In crowded categories, small differences in site performance can make or break your unit economics.
Our CRO Process
1. Audit & Benchmarking
We start with a full review of your site: design, product pages, checkout flow, and analytics — benchmarked against category-relevant standards, not generic averages.
2. Data & Insights
Using heatmaps, session recordings, and GA4 analytics, we identify where users drop off and why.
3. A/B Testing & Experiments
We run structured tests to find what actually improves performance, including:
- Product page layouts and imagery
- Benefit and feature callouts explained in plain language
- Checkout process refinements
- Offer structure — bundles, subscriptions, and free-shipping thresholds
- Placement of reviews, UGC, and trust signals
4. Implementation
Winning changes are rolled out, documented, and systemised so your team can maintain the improvements.
5. Ongoing Optimisation
CRO isn’t a one-off project — it’s continuous. We set up reporting and processes to keep improving your site over time.
What We Focus On
- Product Pages: Clear benefit communication, strong visuals, and answers to the questions that stall a purchase.
- Checkout: Reducing friction, optimising payment options, and building trust with security and guarantees.
- Repeat Purchase: Simple, attractive ways for customers to reorder, subscribe, or come back for the next drop.
- Social Proof: Reviews, UGC, and authority markers in the right places.
- Mobile Experience: Ensuring shoppers can convert easily on the device most of them are using.
