Answers to the most popular questions
I start with an analytics audit (GA4, Mixpanel, Amplitude, Hotjar) and verify event hygiene. Then I map the AARRR funnel, find leaks, run customer interviews to capture JTBD context, and produce an ICE-prioritized hypothesis backlog. Next comes the A/B test plan, execution with your team or mine, statistically significant analysis, and scaling of the winners. The deliverable is a CRO dashboard in GA4 or Mixpanel.
I use a simple formula: severity x traffic x revenue impact. First we look at pages with the biggest drop in the funnel (visible in GA4 Funnel Exploration), then overlay traffic volume and potential MRR/ARR impact. Often this is not the homepage but a category page, a form step, or a checkout step. Hotjar recordings and heatmaps add a qualitative layer: you see frustration, dead clicks, and zones the user keeps trying to tap.
It depends on baseline conversion and the minimum detectable effect. For a B2C store with a 2% conversion targeting a 15% lift, you need about 8-12 thousand visitors per variant. If you have less, I recommend not splitting traffic but working through qualitative hypotheses with interviews, usability tests, and sequential iterations. A check-the-box A/B test is worse than no test at all.
HEART (Happiness, Engagement, Adoption, Retention, Task success) prevents tunnel vision on purchase conversion. I use it to make sure conversion gains do not destroy long-term metrics like retention or NPS. In cases where I lifted checkout conversion, HEART saved us from situations where an aggressive CTA brought a quick lift but increased refund rate and churn.
I analyze the mobile funnel separately because in Chernivtsi mobile traffic is often 70-80%. I check Core Web Vitals (LCP, CLS, INP), load speed, form behavior on iOS and Android, readability, and thumb-zone tap targets. Hotjar mobile recordings reveal real scroll patterns. Often 30-40% of growth potential lives in mobile UX, not desktop.
Yes, because without post-click work CRO delivers only half the result. I configure trigger email flows in SendPulse, eSputnik, Klaviyo, or Brevo, retargeting in Meta and Google Ads, and push scenarios. This matters especially for DTC Bukovyna wineries with long decision cycles where users return 3-5 times before buying. I tie these channels to GA4 events to see real channel ROI.
A standard cycle is 3 months: one month for audit and test launch, two months for iteration. The first winning tests usually appear at week 4-6, with cumulative effect at weeks 8-12. For serious ROI growth I recommend a 6-9 month partnership where we squeeze systemic improvements across channels and build an internal CRO practice in the client's team.
I always work with cohort analysis and look at post-purchase retention, repeat orders, LTV, and refund rate, not just a one-time conversion lift. I set up a dashboard in Looker Studio or Mixpanel that shows test impact over time. If the lift fades after 4 weeks, it was a novelty effect, not a real win. Honest analytics is the main value of a CRO consultant.
For Bukovyna winemakers I work on three points: the wine variety page (terroir story, awards, food pairings, mapped to JTBD of gift and dinner), the wine-club subscription page, and the checkout with age verification. Hotjar shows exactly where users stall, often the delivery address field. The strategic side I cover in product strategy in Chernivtsi.
Tourism portals about Chernivtsi (Kobylianska, the Town Hall, Soborna, Turetska) have specific dynamics: the user is not yet sure they will come, not yet familiar with the map. I recommend segmenting landing pages by JTBD: weekend from Kyiv, tour from Lviv, transit from Romania. Conversion grows when we add interactive routes, honest photos, local reviews, a booking form with date presets, and a CTA to subscribe for those not ready to book yet.
Cross-border stores in Chernivtsi serve customers from Romania and Moldova. Key CRO hypotheses: correct language and currency detection by IP, transparent customs and VAT rules, local payment methods (RON, EUR, MDL), and integration with Romanian and Moldovan carriers. Often 20-30% of potential is lost on the checkout page due to confusing shipping calculation. The strategic frame for cross-border products I cover in product strategy in Chernivtsi.
For SaaS teams in Chernivtsi IT Cluster, CRO is about activation and onboarding metrics. I analyze the path from sign-up to the aha moment, find drop-off points, and test onboarding flows, in-app prompts, and the first 14-day email sequence. Key metrics are TTV (time to value), W1 retention, and trial-to-paid conversion. More service details on the conversion optimization page.

Chernivtsi is a city of 265 thousand that combines UNESCO Austro-Hungarian heritage, the academic strength of Yuriy Fedkovych Chernivtsi National University, the medical expertise of Bukovyna State Medical University, the momentum of Chernivtsi IT Cluster, and a strong entrepreneurial layer: Bukovyna winemaking, tourism around Kobylianska and Soborna, gastronomy, and cross-border trade with Romania and Moldova. Together they form a very textured digital-product market where classic best practices from Western blogs often miss. I am Oleksandr Filyuk, 15+ years and 130+ products in CRO, and I work with companies in Shevchenkivskyi and Pershotravnevyi districts to finally turn traffic into revenue.
I do not believe in 10-point best-practice quick wins. My approach is systematic CRO: first an analytics audit of GA4, Mixpanel, Amplitude, and Hotjar, then event-hygiene checks and AARRR funnel mapping. After that, JTBD customer interviews to understand context, triggers, and barriers. Hypotheses are prioritized via ICE, not gut feeling. A/B tests run with calculated sample sizes and honest statistical significance. The HEART framework keeps us safe: we do not just lift conversion but also protect retention, NPS, and LTV. Everything is captured in a dashboard the client's Chernivtsi team keeps using after the project ends.
The base stack is GA4 for top-of-funnel and product analytics, Mixpanel or Amplitude for deep product analytics (cohorts, retention cubes, behavioral flows), and Hotjar for the qualitative layer (heatmaps, recordings, surveys). For testing, VWO, AB Tasty, or custom feature flags. For dashboards, Looker Studio and Mixpanel's built-in views. I design the system so data stays clean, events are standardized, and the team can run and validate hypotheses on its own. Across 130+ projects I have seen that half of CRO problems are not design but dirty analytics producing wrong conclusions.
Over years of practice in Chernivtsi I have focused on four segments. First, Bukovyna DTC wineries selling online via subscriptions and wine clubs. Here CRO covers wine variety pages, age-verified checkouts, and post-purchase flows. Second, tourism portals working with Chernivtsi, Kobylianska, the Town Hall, and Turetska traffic. The key is landing-page segmentation by traveler JTBD. Third, cross-border e-commerce aimed at Romania and Moldova, where we need to nail currency, language, and delivery. Fourth, Chernivtsi IT Cluster startups where I work on activation and trial-to-paid conversion. The strategic frame for all of them I cover in product strategy in Chernivtsi.
CRO without product strategy is cosmetics. Strategy without CRO is pretty slides without revenue. I often run both tracks in parallel: product strategy sets the North Star metric and ICP, while CRO executes tactical experiments within that frame. For teams without a clear PMF I recommend starting with strategy and only then investing in systematic CRO. Otherwise you optimize a funnel that drives the wrong users. When strategy exists, CRO becomes the main multiplier of marketing spend ROI.
The first step is a free 45-minute session where we discuss your product, current conversion, traffic volume, and channels. I ask direct questions: is traffic stable, are GA4 events clean, what are your core business metrics (MRR, ARR, AOV, CAC, LTV, refund rate, churn). If I see CRO is not the right priority right now, I will say so honestly and may suggest starting with product strategy or an analytics audit. If you are ready, I send a proposal with three formats: a 2-week express audit, a full 3-month CRO cycle, or a 6-9 month long-term partnership. I work online and offline in Chernivtsi, from an office near the Town Hall to quiet cafes on pedestrian Kobylianska and Turetska. If you run e-commerce, SaaS, or a tourism project in Chernivtsi and want to turn traffic into stable revenue, let's talk.
