Background

The Client

Ventico — an HVAC services company in Warsaw, Poland, focused on air conditioning installation and maintenance. A solid local operation, skilled team, but stuck on one problem: no predictable flow of new customers from online channels.

Problem

The Challenge

They had tried ads before. Money went out, very little came back. The pipeline depended on referrals and luck — not a system. They needed inbound leads that actually picked up the phone and booked jobs, on a budget a small business could justify.

  • No reliable inbound lead source
  • Past ad spend produced clicks but not customers
  • Small budget — every dollar had to work
What I did

The Approach

Instead of just "running ads," I rebuilt the entire funnel from intent to booked call.

  • Market & target audience research — who actually buys AC installation in Warsaw, when, and why
  • Built and optimized the Google Ads campaign from scratch with a clean account structure
  • Refined keyword targeting to focus only on high-intent buyer searches — cut the tire-kickers
  • Improved campaign structure for higher quality scores and better lead quality
  • Built a high-converting landing page matched to ad intent — one offer, one action
  • Focused every step on converting traffic into paying customers — not vanity clicks
The Results

8 paying customers from $253 in ad spend.

Takeaway

Key Insight

High-intent search traffic combined with proper campaign structure can generate profitable results — even with a small budget. You don't need $3,000/month to make Google Ads work. You need the right keywords, the right copy, and a landing page that does its job.
