Conversion Rate Optimization (CRO)
More revenue from the traffic you already pay for—guided by evidence, not guesswork.
Pouring more ad spend into a leaky funnel is the most expensive mistake in digital marketing. We use rigorous behavioral analytics, session replays, and pre-registered A/B experiments to systematically eliminate friction, turning your existing visitors into paying customers and compounding your revenue.
What Weak Implementation Is Costing You
When this capability is neglected or outsourced to junior teams, these specific failure modes erode revenue and brand equity:
Customer Acquisition Cost (CAC) continues to rise across Google and Meta, eroding profit margins.
Internal marketing debates driven by subjective opinions and HIPPO (Highest Paid Person's Opinion) instead of data.
Broken analytics tracking (double-counted pageviews, missing purchase values) making data untrustworthy.
Running chaotic A/B tests that 'win' in the tool but fail to produce measurable lift on the balance sheet.

Curated Tech Stack & Selection Rationale
Every tool in our stack is chosen for verifiable performance, security compliance, and long-term maintainability.
Why this choice: Bypasses ad-blocker drop-offs with first-party cookies while adhering strictly to European GDPR privacy regulations.
Why this choice: Provides unfiltered session recordings, rage-click heatmaps, and dead-click analytics to pinpoint exact frustration moments.
Why this choice: Statistically sound split testing engines with Bayesian and Frequentist evaluation models that prevent false positive results.
Why this choice: Captures qualitative 'why' behind user drop-offs via exit-intent micro-surveys and targeted user feedback.

Tailored 6-Phase Execution Roadmap
Structured phases with concrete activities, client involvement time, and rigorous exit criteria.
Phase 1: Tracking Audit & Instrumentation Fix
Phase Goal: Ensure tracking data is 100% reliable before designing a single experiment.
Key Activities:
- •Audit GA4, GTM, Meta CAPI, and Google Ads conversion tag configurations
- •Verify purchase event values, currency conversions, and deduplication IDs
- •Implement server-side tagging to recover data lost to ad-blockers and Safari ITP
- •Configure Google Consent Mode v2 ensuring GDPR compliance without losing attribution
Deliverables:
Tracking Audit & Data Hygiene Remediation Report • Clean GA4 & Server-Side GTM Container Configuration
Client Involvement:
Access to analytics, tag manager, and ad accounts.
Exit Sign-Off Criteria:
Analytics purchase data matches backend financial records within 3% variance.
Phase 2: Qualitative & Quantitative Research
Phase Goal: Uncover where and why visitors are dropping out of your conversion funnels.
Key Activities:
- •Analyze funnel drop-off rates across devices, traffic channels, and browser types
- •Review 100+ session recordings to identify rage clicks and UX stumbling blocks
- •Deploy unobtrusive exit-intent micro-surveys asking why visitors aren't converting
- •Conduct heuristic evaluation of value proposition, clarity, and perceived risk
Deliverables:
Friction & Heuristic Audit Report with video clip evidence • Customer Friction Persona Matrix highlighting objections
Client Involvement:
1 hour debrief on user friction findings and survey insights.
Exit Sign-Off Criteria:
Identified top 5 friction themes backed by quantitative and video evidence.
Phase 3: Hypothesis Formulation & ICE Prioritization
Phase Goal: Formulate testable, pre-registered hypotheses and calculate required sample sizes.
Key Activities:
- •Draft hypotheses using formal structure: 'Because we saw [data], we believe [change] will cause [outcome]'
- •Calculate minimum detectable effect (MDE), required sample size, and test duration
- •Score all opportunities using the ICE framework (Impact, Confidence, Ease)
- •Plan the quarterly testing roadmap with pre-registered primary metrics
Deliverables:
Prioritized Experimentation Backlog with statistical power calculations • Quarterly Testing Roadmap locked with stakeholder approval
Client Involvement:
1 hour roadmap prioritization alignment meeting.
Exit Sign-Off Criteria:
All upcoming experiments have pre-calculated sample sizes and run-time estimates.
Phase 4: Test Design & Engineering
Phase Goal: Design and build pixel-perfect test variants with zero flicker or performance drag.
Key Activities:
- •Design high-fidelity UI variants in Figma addressing specific behavioral barriers
- •Code test variants in lightweight, performant JavaScript/CSS without visual flicker
- •Configure experiment audience targeting and traffic allocation rules
- •Perform cross-browser and cross-device QA testing on staging environments
Deliverables:
Figma Test Variant Mockups • Production-tested experiment variants deployed to testing platform
Client Involvement:
Async sign-off on visual design of test variants.
Exit Sign-Off Criteria:
Zero visual flicker (FOOC) and 100% verified tracking events on both variants.
Phase 5: Experiment Execution & Statistical Evaluation
Phase Goal: Run tests to statistical validity without peeking or premature stopping.
Key Activities:
- •Run experiment until pre-calculated sample size and statistical power are achieved
- •Enforce strict 'no peeking' rule to avoid false positive statistical traps
- •Analyze results using Bayesian probability of best and frequentist confidence intervals
- •Segment results by device, traffic source, and visitor type to uncover nuances
Deliverables:
Comprehensive Experiment Analysis Report with statistical significance calculations • Learnings documentation added to your company's experimentation archive
Client Involvement:
Bi-weekly review call discussing test outcomes and strategic takeaways.
Exit Sign-Off Criteria:
Statistically conclusive result reached (95%+ confidence or confirmed neutral).
Phase 6: Rollout & Continuous Compounding
Phase Goal: Hardcode winning variants directly into production and feed learnings into the next sprint.
Key Activities:
- •Commit winning variant code directly into your production Next.js codebase
- •Retire experiment in testing tool to eliminate ongoing JavaScript payload overhead
- •Synthesize qualitative learnings to inform copy, messaging, and product roadmap
- •Queue the next prioritized hypothesis in the sprint pipeline
Deliverables:
Production Pull Request containing clean, permanent implementation of winning variant • Updated Experimentation Archive with compounded revenue impact metrics
Client Involvement:
Review and merge production pull request.
Exit Sign-Off Criteria:
Winning changes running in native production code with measurable revenue gains.
