Zatamni Stakla

A window tinting business in Zagreb was relying entirely on Instagram DMs and word-of-mouth to generate leads. No website, no search presence, no way to capture inquiries outside business hours. Peak season (April–August) was approaching, and the owner needed to start converting search traffic into booked appointments -fast.

The challenge wasn't just building a page. Croatian regulations around window tinting are strict and frequently misunderstood, which meant the site also needed to serve as an authority resource to build trust before the first message is ever sent.

I built a conversion-focused landing page with a dual CTA strategy: WhatsApp messaging and a structured contact form, both given equal weight throughout the page. The design follows a dark, premium automotive aesthetic that matches the service's positioning -this isn't a budget shop, and the site shouldn't feel like one.

The content strategy went beyond the landing page. I wrote 8 long-form SEO articles covering topics like Croatian tinting laws, ceramic vs. standard film differences, and maintenance guides -all structured as a hub-and-spoke model linking back to the main page. An interactive before/after gallery with drag sliders lets visitors see real results, not stock photos.

A dedicated /hrvatska subpage targets customers outside Zagreb willing to travel, opening up a nationwide audience for paid ads.

I deliberately chose a zero-framework stack: plain HTML, CSS, and vanilla JS on shared hosting. No React, no Next.js, no build step. For a local service business, the complexity tax of a framework buys nothing -but a 87+ Lighthouse performance score, 100 accessibility, and sub-3-second loads on shared hosting buy everything.

PHP includes handle shared components across the 10+ pages. PHPMailer with Google SMTP replaced the initial mail() approach after discovering the host blocked port 587. Form protection uses honeypot fields and IP-based rate limiting rather than a heavy CAPTCHA dependency. FAQ and LocalBusiness schema markup are baked in for rich snippets. Meta Pixel tracks WhatsApp clicks and form submissions as Lead events.

The site went live mid-March 2026, indexed and ranking before peak season hit. The owner went from zero web presence to a fully instrumented lead generation system -organic search, paid ads, and social all funneling into two clear conversion paths. The content hub positions the business as the authority on window tinting in Croatia, not just another service listing. Total footprint: ~3MB, 10 indexed URLs, zero ongoing infrastructure cost beyond €30/year hosting.
