CASE STUDY — 01
Pantera Family & Sport Club
Mokotów, Warsaw
Full redesign for a Warsaw martial arts and family sport club — a custom hand-coded WordPress theme, no page builder. First three weeks live — enquiries almost daily, ~3.5% of sessions ending in an enquiry, Google search traffic up by half.

The Brief
My Role
Before / after — old WordPress hero next to the new looping cut.
Results — first three weeks
Google Analytics 4, 31 August – 20 September 2026. Three weeks of live data after launch.
Contact requests arrived nearly every day — through the sign-up form and the direct phone, email, and WhatsApp links. Every CTA on the site ends in one of those channels by design.
Roughly one visitor in thirty took a contact action. For a local service site with no online checkout, this is the number the whole design was aimed at.
Traffic from Google search grew by about half compared with the week before launch. Part of that is the start of the school year — the honest read is the redesign and the season pulling in the same direction.
Around 40% of sessions included a schedule view — visitors moving past the homepage into planning a real visit. Members also started paying online within the first weeks.
Lighthouse before & after
The number that matters most is Cumulative Layout Shift — 0.235 → 0.015 — the only Core Web Vital users physically feel as the page loads.
Four decisions that shaped the site
The full case study walks through eight decisions, the rejected layouts, and the performance work in detail — these four carry most of the result.
- 1Video hero over photographyA hand-edited 10-second loop of real training — kids first, then adult Krav Maga, then Tai Chi. Authentic proof of the training environment, not a stock substitute.
- 2Audience segmentation below the foldThree cards route parents, adults, and companies immediately. The page asks one question — which class are you here for? — and routes, instead of trying to be one thing.
- 3Every CTA ends in a conversationPantera has no online checkout — the sales process runs through a free trial class. No "most popular" badge, no dead-end buttons; each path leads to a human.
- 4Custom theme, no builderA WordPress theme written from scratch — hand-coded templates, no page builder, no plugin bloat — on ordinary hosting. Editors edit content, never layout.
