Why a solo expert, not an agency

CRO agencies work at scale. They have processes, templates, and teams. That works well for large enterprises with dedicated marketing operations teams who can manage an agency relationship. For most e-commerce stores, it's overkill and expensive overkill at that.

The problem with agencies is the handoff chain. You brief the account manager. The account manager briefs the strategist. The strategist directs the analyst. The analyst produces the report. The copywriter writes it up. By the time you receive findings, they've been filtered through four people who each understood your situation slightly differently. The result is often generic recommendations that could apply to any store.

With a solo expert, there's no handoff chain. You talk directly to the person who has 20 years of e-commerce UX experience, who has worked with ADIDAS, LEGO, KLM, Philips, Bol.com, and ANWB, and who is doing the analysis personally. The recommendations are specific to your store because the person making them actually knows your store.

The output is also different. An agency delivers a presentation designed to justify the agency's value. A solo expert delivers findings designed to be implemented. Developer-ready briefs. Prioritized by revenue impact. Written for your team, not for a pitch deck.

Research-backed, not opinion-driven

Most CRO consultants work from best practices lists and personal experience. That's a starting point, not a methodology. Baymard Institute has conducted more than 95,000 hours of UX research specifically on e-commerce. Their database covers 40,000+ retail websites and 500+ UX guidelines tested against actual user behavior.

BTNG.studio's analysis uses Baymard's research as the benchmark layer. When we identify a problem in your checkout, we can reference the specific Baymard finding that explains why it's a problem and what the tested solution is. This means recommendations aren't based on what a consultant thinks looks better. They're based on what hundreds of hours of user testing has shown actually works.

On top of Baymard, every engagement starts with your GA4 data. The analytics tell us where customers are leaving. Session recordings tell us why. The Baymard framework tells us what the fix should be. Recommendations come from all three sources, not from one consultant clicking around your store for an afternoon.

Frequently asked questions

What makes you different from a CRO agency?

When you hire an agency, you talk to an account manager, a strategist handles your brief, a junior analyst runs the audit, and a copywriter writes the report. Four people, none of whom know your store as well as you do, and all of whom are working on multiple clients at once. With BTNG.studio, you talk directly to the person doing the work. 20+ years of UX experience, Toptal Top 3%, CXL Certified in CRO. No handoffs, no account management overhead, no interpretation loss between what you said and what gets analyzed.

How do you charge for CRO consulting?

Fixed-price deliverables for audits, not hourly rates. You know the cost before you start. For ongoing consulting engagements, we scope clearly defined monthly deliverables with defined outcomes. No open-ended retainers where the scope drifts. Pricing is on the research page.

What results can I realistically expect?

It depends entirely on where you're starting from and what problems we find. A store with a clear checkout problem that gets fixed can see conversion rate improvements of 0.3-0.8 percentage points within weeks. A store that's already well-optimized will see smaller gains from any single change. ANWB saw €2.8 million in annual savings from a structured audit and redesign engagement. That's an unusually large number from an unusually large store. More typical: a 1-2% conversion rate improvement on a store doing €2M annually translates to €20,000-€40,000 in additional revenue. The audit costs a fraction of that.

Do you work with international stores?

Yes. Most work is for Dutch and European e-commerce stores, but the methodology works regardless of market. For non-Dutch stores, we don't bring in EU-specific knowledge where it's not relevant. ADIDAS global e-commerce work covered multiple markets. KLM's digital products serve an international audience. The fundamentals of e-commerce UX don't change by country, but the specific friction points do.

How long does a CRO engagement take?

A standalone audit takes 5-7 business days to deliver. Implementation support can run for 4-12 weeks depending on what the audit finds and how quickly your team can implement. Ongoing monthly consulting engagements typically run in 3-month increments with defined deliverables. There are no minimum term requirements for most engagements.
