The symptoms

Four signs your store needs CRO.

CRO isn't for sites that are already converting well. It's for the ones bleeding money at a specific point in the funnel — usually one you can't see from the dashboard alone.

Traffic's fine, sales aren't

Ads bring visitors, Google ranks pages, Meta drives clicks — but the checkout stays quiet. CRO tells you exactly where visitors are dropping, not guessing.

Buyers click, pause, then leave

Session recordings show visitors inches from converting — then bouncing on a hidden shipping cost, a confusing variant picker, a broken mobile button. Small friction. Big losses.

Mobile flops while desktop flies

80% of traffic now mobile. A brilliant desktop UX means nothing if the mobile tap targets are cramped and the form keyboard keeps flipping. Where most Irish stores leak.

You're guessing at what to fix

Without testing, every 'optimisation' is a HiPPO decision (Highest Paid Person's Opinion). A/B testing turns fixes into evidence. No more arguing about colours.

How we run CRO

Three phases — diagnose, hypothesise, test.

CRO isn't copywriting tweaks and prayer. It's a repeatable three-phase cycle that turns your traffic into compounding improvements — one tested change at a time.

01 · Diagnose

Where are visitors actually dropping?

GA4 funnel analysis by device + traffic source
Hotjar / Microsoft Clarity session recordings
Heatmap analysis on key pages
Mobile-specific behaviour deep-dive
Exit-intent patterns per step
02 · Hypothesise

What would actually move the needle?

Prioritise fixes by impact × effort (PIE)
ICE scoring for each hypothesis
Mobile-first testing priority
Test one variable at a time
Define success metric upfront
03 · Test

Prove it, don't assume it

Google Optimize alternatives (Optimizely, VWO, PostHog)
Minimum sample size calculated
Run until statistical significance
Segment results by device / source
Document learning regardless of winner
Six CRO disciplines

Different pages, different optimisation playbooks.

The fixes that help a landing page aren't the fixes that help a product page. We test with the right methodology for each surface.

Landing page CRO

Hero, proof, CTA placement. Turn paid traffic into something.

Product page CRO

Variant pickers, stock urgency, trust signals, sticky add-to-cart.

Cart CRO

Free-shipping thresholds, upsells, exit-intent recovery.

Checkout CRO

Form fields, guest checkout, wallet payments, progress clarity.

Mobile CRO

Thumb-zone buttons, faster forms, single-column flows.

Post-purchase CRO

Thank-you upsells, referral prompts, email capture.

When CRO pays back fastest

Eight trigger situations for us to step in.

These are the scenarios where CRO investment returns within a quarter. If any describe your store, it's probably time.

Conversion rate below industry benchmark
Paid traffic not converting
Mobile conversion notably worse than desktop
Cart abandonment above 70%
Checkout abandonment above 30%
Launching a new product line
Pre-peak season UX tuning
Post-migration conversion dip
Common questions

CRO questions, honestly answered.

The questions Irish SMBs ask us most often.

Varies hugely by category. Fashion/apparel: 1.5–3%. Electronics: 1–2%. Food & drink: 2–4%. Services/booking: 3–8%. Luxury: 0.5–1%. We'll benchmark your specific category on your first audit — pointless comparing a fashion site's 1.8% to a specialist food shop's 4%.
Quick wins from heuristic audit (no testing): usually within a month. Real A/B test wins: 2-6 weeks per test depending on traffic. For stores under 2k visits/month on a key page, A/B testing statistically doesn't work — we use qualitative methods (session recordings, heatmaps) instead. Over 10k/month and testing becomes fast.
Yes and no. We can list 20 things likely to help based on experience — heuristic audit. Some will work, some won't, some will hurt. That's why we also test the high-impact ones. For low-risk obvious fixes (broken buttons, missing prices) — just fix. For big structural changes — test first.
Hotjar or Microsoft Clarity (session recordings + heatmaps — Clarity is free and excellent). GA4 for funnel analysis. PostHog, Optimizely, or VWO for A/B testing. Survey tools (Typeform) for qualitative insights. The tools matter less than the methodology — we've run good programmes on free-tier stacks.
Any platform where we can install tracking and make changes. Shopify, WooCommerce, Magento, BigCommerce, custom builds — all fine. Squarespace/Wix limit what we can change (can't always edit checkout properly), which constrains what CRO can achieve there.
Project-based for audits (discovery + recommendations) or monthly retainer for ongoing testing programmes. Typical entry point: €1,500–3,000 audit → then €1,500–5,000/month retainer depending on testing volume. We'll share specific scope after seeing your current metrics. Free 30-minute audit call to scope.
