Opinion CRO vs Scientific CRO

The problem with the "CRO" you know.

Traditional agencies: change button colors because it "will look better", don't calculate sample size, and stop tests when they see green. We: hypotheses based on data, sample size calculated before starting, tests run until significance, and documented learnings. Every test has demonstrable statistical validity.

Access to A/B tool (we provide if you don't have)
Load time <3s to avoid contaminating tests
Ability to quickly deploy winners (no months-long queue)
CRM integration for tracking real revenue, not just leads

Is It for You?

CRO requires sufficient traffic to validate tests. If you don't have 10K visits/month, start there.

Who it's for

  • E-commerce or SaaS with +10,000 visits/month (minimum for significance).
  • Companies that measure revenue and margin, not just conversion counts.
  • Teams with ability to implement changes quickly on the website.
  • Organizations that make data-driven decisions, not opinion-based.
  • Businesses with validated product-market fit looking to optimize, not validate.

Who it's not for

  • Sites with less than 5,000 visits/month (tests won't reach significance).
  • Companies wanting "design changes" without measuring impact.
  • Organizations where every change requires months of approval.
  • Businesses without revenue tracking attributed to web.
  • Websites with severe technical issues (better to fix first).

Optimization Areas

Where we apply CRO with greatest impact.

01

Landing Pages and Home

Value proposition optimization, above the fold, and primary CTAs. Headline, social proof, and friction reduction tests. Typical impact: +15-30% in conversion.

02

Checkout Funnel

Cart abandonment reduction: guest checkout, progress indicators, trust signals, payment options. Tests on each funnel step. Typical recovery: 10-20% of abandonments.

03

Product Pages

Description, images, reviews, urgency optimization. Layout, pricing display, cross-sell tests. Focus on Average Order Value, not just conversion.

04

Forms and Lead Gen

Field reduction, progressive profiling, multi-step forms. Copy, incentive, and timing tests. Typical improvement: +20-40% in completion rate.

Work Process

From audit to continuous optimization.

01

Audit and Discovery

Heuristic analysis, heat maps, session recordings, surveys. Generation of 20+ prioritized hypotheses backlog by impact x confidence. Free initial audit.

02

Setup and First Tests

A/B tool setup, goal configuration, variant design. Launch of first 2-3 tests with calculated sample size.

03

Iteration and Scale

Results analysis with 95% significance. Winner implementation. Learning documentation. Weekly meetings with business metrics.

Risks and How We Mitigate Them

Transparency about what can go wrong.

01

Inconclusive Tests

With low traffic, tests don't reach valid conclusions. Mitigation: we calculate sample size before launch. If insufficient traffic, we prioritize high-impact changes without testing.

02

False Positives

Stopping tests early generates incorrect decisions. Mitigation: mandatory 95% significance, we don't stop even if we see green. Multiple variant correction.

03

Optimizing Wrong Metrics

Increasing conversion can decrease revenue if you attract low-value customers. Mitigation: we measure Revenue per Visitor, not just conversion rate. CRM integration for real value.

04

Implementation Speed

Unimplemented winners don't generate value. Mitigation: we agree on implementation SLA before starting. We prioritize tests the team can deploy quickly.

Scientific Optimization Specialists

We're not an agency that "runs tests". We've been optimizing conversions for 15 years with rigorous statistical methodology. Every test has documented p-value, calculated sample size, and structured learnings. Fixed fee because we believe in aligning incentives.

Frequently Asked Questions

What decision-makers ask before hiring.

How much traffic do I need for CRO?

For statistically significant tests: minimum 1,000 conversions/month on the target metric. With less, tests take too long or don't reach significance. Rule of thumb: 10,000+ visits/month.

How many tests can you run per month?

Depends on traffic, but typically 2-4 simultaneous tests in different funnel areas. A test takes 2-4 weeks to reach 95% significance. We prioritize by potential impact.

Do you guarantee results?

We guarantee rigorous methodology and statistical validity. Not all tests win (typical rate: 60-70%), but we document learnings from each. ROI comes from cumulative effect.

Why Revenue per Visitor and not Conversion Rate?

You can increase conversion by 50% and lose money if new customers buy low-margin products. RPV captures rate + value. It's the metric that matters to the business.

What happens if a test doesn't reach significance?

We don't declare a winner. An inconclusive test means the difference is too small to detect with your traffic. We document the learning and decide whether to scale the test or move to another hypothesis.

How do you avoid false positives?

Three mechanisms: pre-test calculated sample size, 95% significance minimum, and multiple variant correction. Plus, we validate with segmented analysis.

CRO or complete redesign?

If your website has fundamental UX or technology problems, redesign first. CRO optimizes what already works reasonably. Don't optimize a car without an engine.

Do you work with companies outside Spain?

Yes, we're a CRO agency with 15+ years experience. We work with local, national, and international clients. Video conference meetings available.
