Overview

A full website redesign for an online German language school — 9 pages, new brand identity, mobile adaptive — that tripled traffic and engagement within weeks of launch.

The product dehto school is a Ukrainian online German language school offering individual lessons, video courses, split sessions, and speaking clubs. The client came with an existing dark-themed website and a clear ask: make it modern, recognizable, and different from every other language school online.

The project covered the full design scope — competitive research, brand identity, UX architecture, and UI across all 9 pages including mobile adaptive. This project was delivered while leading a design agency, where I was the lead designer on the engagement.

Background

A product people trusted — a website that didn't reflect it.

Dehto had built a real community of German learners with strong course content and active instructors. But the website told a different story: a dark, text-heavy layout with low visual hierarchy, no clear differentiation from competitors, and conversion paths that were hard to find.

Target audience: 16–40 year olds learning German for relocation, work, travel, or university — a demographic that judges credibility by design before reading a single word of copy.

The GA4 data before redesign confirmed the issue:

  • page_view: 3,600

  • user_engagement: 2,900

  • first_visit: 800

  • form_start: not tracked — the form wasn't converting enough to measure

Challange

Stand out. Convert. Feel native on mobile.

The design had to solve three things simultaneously:

1 — Differentiation Every Ukrainian language school looks the same — stock photos, blue-green palettes, generic hero sections. dehto needed a visual identity that was immediately recognizable and felt like a brand, not a template.

2 — Conversion The existing site buried its CTAs and had no clear visual hierarchy between the school's offerings — individual lessons, video courses, and speaking clubs competed for equal attention. The redesign needed to guide users toward action.

3 — Mobile experience A 16–40 audience discovers through Instagram and Telegram. The previous site had no intentional mobile design. Every page needed a full responsive adaptive.

Discovery

Competitive audit + GA4 analysis.

  • EnglishDom — strong brand, clean pricing pages, good mobile

  • GreenForest — high trust signals, instructor-forward design

  • JustSchool (justschool.me) — modern UI, clear course hierarchy

  • BeebestSchool (bebestschool.com) — good course card design

  • Preply — international benchmark for individual lesson UX

  • Goethe Institut Ukraine — institutional credibility signals

  • SpracheKurs / Deutsch Online — direct German-specific competitors

What competitors do well: clear course hierarchy, instructor photos with credibility signals, prominent CTAs above the fold, pricing transparency.

What none of them had: a distinctive visual personality. Most looked interchangeable. This was dehto's opportunity.

GA4 audit findings:

  • Homepage had the most traffic but lowest engagement time — users landing and leaving

  • "Подати заявку" page had only 125 views — CTA discovery was broken

  • Video progress events were low — course pages weren't reaching scroll depth

Thinking

Brand first. Then conversion.

Brand identity Developed a custom visual system: bold typography, high-contrast layout, a distinctive character mascot used as a recurring element across pages. The goal was a design that felt energetic and approachable for a 16–40 audience — not corporate, not generic.

Hypotheses that shaped the design:

  • H1: A recognizable mascot/character increases brand recall and return visits

  • H2: Clear service hierarchy (individual → video → clubs) reduces decision fatigue and increases CTA click-through

  • H3: Showing instructor faces and credentials on landing increases trust and form submissions

  • H4: Adding partner logos (Monobank etc.) above the fold increases perceived legitimacy

  • H5: Mobile-first navigation with sticky CTA increases application submissions from mobile

Page architecture 9 pages structured around the user's decision journey — from discovery (home) to course-specific pages, to application. Each page had one primary CTA. No page competed with another.

Outcome

9 pages. One consistent system.

The homepage — the primary brand entry point — went from 901 views to 3,000+ in the same measurement period. Form starts were now trackable, meaning users were actually reaching and engaging with the conversion page.

Testimonial

The process was smooth. The design perfectly captured our spirit and expectations. Working with Oleksandr was an absolute pleasure! Having a clear brief is one thing, but finding the right person to execute it is everything — and he was a perfect match in every aspect. Huge thanks for the consulting, the right questions, and your constant support. Most importantly, the design completely nailed our company's tone of voice and delivered exactly what we wanted. That level of understanding is priceless!
