The client

InstaKółko runs a year-round online programming course for children and teenagers — Assembly, Python and C++. The buyer isn't the student, though: it's the parent. That shapes everything about how the ads have to speak.

The challenge

One clear goal: generate enrolment leads on the client's website. For a niche education product, that means reaching the right parents at the right moment — and bringing back the ones who showed interest but didn't sign up.

What we did

We built the strategy, set the objectives, and configured two complementary Google Ads campaigns:

  • A Search lead-generation campaign with two ad groups: new parents via detailed demographic targeting, and a remarketing group reaching everyone who'd visited the site in the last 90 days.
  • A Performance Max traffic campaign to drive qualified page views and feed the funnel.

The results

Over the first six months the campaigns generated 641 enrolment leads at an average of 23 zł each (≈ €5.30) — with the Search campaign holding a 3.54% click-through rate on nearly 400,000 impressions.
