CRO Retainer Program

The conversion work never stops. Every month, we find new leaks, test new hypotheses, and squeeze more revenue from your existing traffic.

Start This Engagement

A website is not a static brochure; it is a living revenue engine that degrades over time if not constantly tuned. The CRO (Conversion Rate Optimization) Retainer is for businesses that have established product-market fit and significant traffic, but recognize they are leaving 20% to 40% of their potential revenue on the table every single month.

We embed directly into your growth team. Every month, we deploy mathematically rigorous A/B tests against your highest-value pages. We test aggressive copy variations, micro-interaction friction points, pricing architectures, and trust-signal placements.

Compounding Returns: A 15% lift in conversion rate in Month 1, followed by a 10% lift in Month 2, compounds over the year to fundamentally change the enterprise valuation of your company. We operate purely on data. If a test fails, we learn. If a test wins, we hardcode the deployment and push it to production immediately.

Our process for this engagement.

01

The Baseline Index

We establish an uncompromising data baseline, ensuring your analytics are perfectly tracking micro-conversions before we run a single test.

02

Hypothesis Generation

We map out a 90-day testing roadmap based on behavioral friction points identified in session recordings and heatmaps.

03

Design & Deployment

We design the variations and deploy the tests using enterprise tools (VWO, Optimizely, PostHog) to ensure statistically significant results without flickering.

04

Winner Hardcoding

Once a test hits 95% statistical significance, we immediately hardcode the winning variation into your Next.js application.

Who this is actually for.

IDEAL FIT

  • Organizations that view their digital presence as a revenue engine, not just an expense.
  • Teams ready to deploy capital for exponential, measurable ROI.
  • Founders and executives who value speed of execution and elite quality.
  • Companies experiencing scale that has outpaced their current infrastructure.

X NOT A FIT

  • Businesses looking for the cheapest vendor rather than the highest ROI.
  • Committees that require months of deliberation for minor decisions.
  • Those looking for a "digital brochure" without a monetization strategy.
  • Startups without product-market fit or a verified marketing budget.

We don't build deliverables. We engineer assets.

Traditional agencies treat CRO Retainer Program as an isolated deliverable. They assign a junior team, follow a templated checklist, and hand over an asset that looks pretty but does absolutely nothing to move the needle on your revenue.

At BIGWEB Digital, we operate as an extension of your growth team. Every engagement is rooted in Conversion Physics. We audit the friction in your current funnel, deploy aesthetic authority to instantly build institutional trust, and structure the deployment to maximize immediate financial return.

"Our metric for success is not whether you like the final product. Our metric for success is whether the product drastically increases your enterprise value."

Common inquiries.

How quickly can we start?

Depending on our current bandwidth and your Tier level, we can typically onboard and initiate discovery within 7-14 days of contract signature.

Do you require long-term retainers?

For foundational builds, we operate on a project basis. For revenue scaling and AI systems, we require a minimum 6-month commitment to ensure we have the time to iterate and generate verifiable ROI.

What is expected from our team?

We require a single point of contact with decision-making authority. We do the heavy lifting, but we need your domain expertise during the discovery phase and prompt approvals during sprints.

Are the timelines guaranteed?

Yes. We guarantee the Ongoing optimization timeline for this specific engagement, provided that your team meets the 24-hour SLA for necessary feedback and asset delivery.
