What is conversion rate optimization (CRO)?+
Conversion rate optimization is the structured process of increasing the percentage of site visitors who complete a desired action — purchase, signup, quote request — through research, hypothesis-driven A/B testing, and iterative design changes. Done properly, CRO isn't guesswork: it's session recordings, heatmaps, funnel analytics, and user interviews feeding a prioritized backlog of experiments, each run to statistical significance before a winner ships. It's the discipline of proving what actually moves revenue instead of assuming it.
How much do conversion rate optimization services cost?+
A standalone CRO audit — funnel analysis, heatmaps, session recordings, and a prioritized test roadmap — typically runs $3,000–$8,000 as a one-time engagement. Ongoing CRO programs, where we design, build, and ship tests every sprint, run $4,000–$12,000/month for a single-funnel Shopify or DTC brand, and $12,000–$30,000+/month for multi-market or enterprise catalogs running several concurrent experiments. We also offer a pay-on-results structure for qualifying accounts, where fees scale with incremental revenue rather than a flat retainer. You get a fixed-scope quote within 48 hours of a discovery call.
What sample size do we need before we can call a test?+
It depends on your baseline conversion rate, current traffic, and the minimum detectable effect you care about — not a fixed number. As a rough planning benchmark, detecting a 10–15% relative lift on a 2–3% baseline conversion rate typically needs 1,000–3,000 conversions per variant. We calculate the exact required sample size and test duration before every experiment launches, and we don't call a test — win, lose, or flat — until that threshold and a minimum two full business cycles (to control for day-of-week effects) have both been hit.
How long does a CRO program take to show results?+
Most engagements ship the first live test within 2–3 weeks of kickoff — research, hypothesis, design, and build. A single test typically needs 2–6 weeks to reach significance depending on your traffic. Expect the first statistically significant win inside 60–90 days, and a compounding pattern of lift from month four onward as the backlog of validated wins builds. Programs on lower-traffic sites take longer per test but still land a research-backed roadmap and qualitative wins (UX fixes, checkout friction removal) well before the first quantitative test concludes.
Do we need a minimum amount of traffic to run tests?+
For classic A/B testing to reach significance in a reasonable timeframe, we generally want at least 5,000–10,000 monthly sessions into the funnel being tested. Below that, split-testing individual page variants gets slow and noisy. It doesn't mean CRO is off the table — for lower-traffic stores we front-load qualitative research (session recordings, heatmaps, on-site surveys, user interviews), fix high-confidence UX and checkout friction points directly, and layer in A/B testing on your highest-traffic pages (usually the homepage or best-selling PDP) once volume supports it.
CRO vs UX redesign — what's the difference?+
A UX redesign is a one-time, opinion-led overhaul of how a site looks and flows — new design system, new layout, shipped all at once, validated after the fact (if at all). CRO is an ongoing, evidence-led process: every change starts as a hypothesis, ships as a controlled experiment against a subset of traffic, and only becomes permanent once it beats the original with statistical confidence. We use UX research as an input to CRO, but we don't ship unvalidated redesigns wholesale — a full-site redesign that looks better can just as easily convert worse, and without a test you'd never know.
What's the difference between this and your Shopify Development Agency service?+
Our Shopify Development Agency service builds new stores, custom themes, headless Hydrogen storefronts, and net-new features from scratch — it's for when you need architecture that doesn't exist yet. This CRO service is for optimizing the conversion rate of a store you already have, through research, A/B testing, and checkout and funnel refinement, without a ground-up rebuild. In practice they connect: when a CRO test wins, our development team ships it into your production codebase permanently — you're not stuck waiting on a separate dev queue to implement what we prove works.
Do you actually build the test variants, or just hand us recommendations?+
We build and ship the variant ourselves. Most CRO 'agencies' deliver a slide deck of test ideas and leave implementation to your internal dev team — which is where most CRO programs quietly die, six months into a backlog nobody has time to build. Our engineers implement every test directly in your testing platform and, once it wins, merge it into production. You get a shipped, working experience, not a prioritized wishlist.
What tools do you use for testing and research?+
For experimentation: GrowthBook, Optimizely, and VWO, chosen based on your stack, budget, and whether you need open-source flexibility or a managed enterprise platform. For research: Hotjar, Microsoft Clarity, and FullStory for session recordings and heatmaps; Google Analytics 4 and server-side tracking for funnel data; and structured user interviews and on-site surveys for qualitative signal. On Shopify specifically, we integrate testing at the edge or via theme app extensions so tests don't degrade Core Web Vitals or flicker on load.
What does a typical CRO engagement include?+
A full program includes: a funnel and checkout audit, session recording and heatmap analysis, a prioritized hypothesis backlog scored by expected impact and build effort, experimentation platform setup or audit, ongoing A/B and multivariate test design and build, statistical analysis and reporting each sprint, and a quarterly roadmap review. You get a written test log documenting every experiment run, its result, and why — a compounding asset, not a one-off project.
How do you decide what to test first?+
We score every hypothesis on expected impact, confidence (backed by research signal, not opinion), and build effort — a standard ICE/PIE-style framework — then sequence the backlog to bank quick, high-confidence wins early while bigger structural tests (checkout flow, pricing presentation, navigation architecture) get properly scoped. Checkout and funnel drop-off points usually get first priority since they sit closest to revenue and tend to have the clearest research signal.
Will CRO work if we're an early-stage store with low traffic?+
Yes, but the mix of work shifts. Early on we lean heavily on qualitative research — session recordings, on-site surveys, checkout drop-off analysis, and direct customer interviews — to find and fix obvious friction without waiting on statistical significance. As traffic and conversion volume grow, we introduce formal A/B testing on your highest-traffic pages first, then expand the testing surface as volume allows. We'll tell you honestly on the first call whether your traffic supports formal split testing yet.
Do you only work with Shopify stores, or other platforms too?+
Most of our CRO work is on Shopify and Shopify Plus, where we've been a Partner since 2019 and have deep experience with theme-level and checkout-extensibility testing constraints. We also run CRO programs for brands on WooCommerce, BigCommerce, and custom/headless storefronts, along with lead-gen and healthcare sites where the 'conversion' is a form fill or booking rather than a purchase. The research and testing methodology is platform-agnostic; the implementation details are not, and we scope those specifically for your stack.
How does the pay-on-results model work for CRO?+
For qualifying accounts — generally stores with enough baseline traffic and revenue to make the math work — we structure fees as a percentage of incremental revenue generated by winning tests, measured against a pre-agreed baseline, rather than a flat monthly retainer. It aligns our incentive directly with your P&L: we only get paid when the experimentation program actually grows revenue. We'll walk you through whether your traffic and margin profile qualify on the first call.
