Chernihiv today is not just a city of historical tourism with Chernihiv Detinets and Boldyna Hora, but a hub for DTC brands, SaaS startups, and retail operating across Ukraine and abroad. I'm Oleksandr Filyuk, with 15+ years of practice in conversion rate optimization (CRO) and 130+ delivered projects. I help Chernihiv business squeeze maximum value from every site visit through a systematic approach to A/B testing, user behavior analysis, and UX optimization built around your business model.
Conversion optimization isn't cosmetic changes of 'buy' buttons from green to red. It's a scientific discipline at the intersection of psychology, design, analytics, and copywriting. Every hypothesis goes through ICE or RICE prioritization, is tested via A/B experiment with proper sample size, and implemented only if it brings statistically significant lift. I've seen hundreds of projects where 70% of potential revenue is lost at 5-7 specific funnel points — and my job is to find these points in 2-3 weeks of focused diagnostic work.
My standard CRO stack includes GA4 for traffic and basic conversions with custom events, Hotjar for heatmaps and session recordings, Mixpanel or Amplitude for deep product analytics and funnels, FullStory for session replay in B2B SaaS, Google Optimize or VWO for running A/B tests. For the Ukrainian market I often add integration with ad platform analytics (Facebook Pixel, Google Ads, TikTok Pixel) to see the full picture from traffic to closed deal across attribution windows.
If your company has poorly configured analytics — and in 70% of Chernihiv projects this is the case — I start with audit and tracking plan. We define 15-25 key events (event taxonomy), configure them via Google Tag Manager, verify correctness through Tag Assistant and live session. This is the foundation without which further CRO is impossible: you can't optimize what you don't measure. I build dashboards in Looker Studio or inside Mixpanel where the team daily sees key metrics: conversion, AOV, retention, churn at a glance.
Chernihiv is a city with an active DTC ecosystem: clothing brands, accessories, food products (including the regional food industry output), wood products, musical instruments. Each niche has its CRO specifics. For food DTC, integration with Nova Poshta for delivery is critical; for clothing brands — quality photos on models, size grid with real people, easy returns. For musical instrument manufacturers — video demos, artist reviews, recording capability via CRM integration.
The general specifics of the Ukrainian DTC market — low trust in online purchases: the Ukrainian buyer wants to see quality confirmation and brand reality. So I test: 'about us' photos with the real team, customer reviews with photos, integration with Rozetka reviews, post-purchase email sequences. Separately — mobile optimization: 75%+ traffic of Chernihiv DTC brands is mobile, so all CRO is mobile-first. Apple Pay, Google Pay, Liqpay, Monobank — must-have for Ukrainian checkout completion success rates.
Historical tourism is a separate large CRO niche in Chernihiv. These are hotel and apartment websites near Krasna Square, tour operators organizing excursions to Chernihiv Detinets, restaurants on Mahistratska, festivals and events. For tourism, CRO has its logic: you optimize not just form conversion but the full path from first contact to paid booking, which can take weeks across multiple touchpoints.
I work with key hypotheses: multilingualism (UK/EN/PL — Poles actively interested in Ukrainian history), photo and video content quality (professional shoots instead of stock), integration with Booking.com, Airbnb, GetYourGuide for marketplace traffic, clear CTAs with money-back guarantees, reviews on TripAdvisor and Google Maps. Separately I test landing scenarios for different audiences: cultural tours for Western travelers, gastro-tours with Chernihiv cuisine, religious tourism to Savior-Transfiguration Cathedral. For hotels — booking speed (max 3 steps), mobile checkout, dynamic pricing with transparent communication.
A/B testing is the scientific heart of CRO, but 80% of tests are conducted incorrectly. Most common mistakes: stopping the test after 3 days without significance, testing on too small a sample, ignoring seasonality, no A/A testing to verify stack, parallel tests without collision check. I follow strict methodology: required sample size calculation before test start (via Optimizely-style calculators), minimum 2 weeks duration (to cover 2 weekly cycles), 95% confidence level, segment validation (mobile/desktop, new/returning, country, source).
For low-traffic projects (typically B2B SaaS in Chernihiv with 1000-3000 unique monthly) I apply qualitative methodology instead of A/B: in-depth interviews with 10-15 customers, expert UX audit across 250+ criteria, session replay analysis of 100+ sessions, content gap analysis. This is slower than A/B but gives no less accurate conclusions. For mature e-commerce with 50,000+ monthly traffic I run 2-3 parallel tests on different pages and achieve cumulative 30-60% lift over 6 months consistently.
Most CRO consultants make changes and leave. I'm convinced sustained results are possible only when your team can run CRO independently. So in every project I build a CRO playbook: 30-50 pages with your methodology, hypothesis templates, checklists for new tests, examples of successful and failed experiments. I run workshops with the team (PM, marketing, designer, developer) in Chernihiv or online, where I teach formulating hypotheses, reading statistical results, avoiding interpretation errors.
After 30 and 60 days post active phase, I run free check-in sessions where we discuss new team tests, adjust the playbook, add new hypotheses. This is part of my philosophy: I don't lock knowledge behind a paywall, I build long-term competency inside your business.

If your site receives 1000+ targeted visitors monthly but conversion is 'stuck' — that's a signal CRO will help. Write me through the website form or LinkedIn with a short description: niche, traffic volume, current conversion, key question. I respond personally within 24 hours on business days. On the first 30-minute free call we'll discuss your context, I'll give 2-3 practical insights based on a quick site review, and we'll determine if there's a fit for collaboration. I work with companies from Chernihiv, all of Ukraine, and internationally across timezones.
