Where we started

Three knots to untangle before we could scale.

01
A closed system, no way in

A strict security policy meant no direct access to Google Tag Manager. So we wrote a tag plan so precise Schrack's own developers deployed every tag flawlessly.

02
A blank page, no ad history

Zero prior campaigns, no benchmarks. Deep market research was our only compass for a strategy that would hit the mark from day one.

03
The phone-call mystery

A big share of B2B sales close over the phone, with no call tracking in place, a real blind spot on which Google clicks became conversations.

What we did

Two clear goals. Both beaten early.

We came in with measurable targets and made the store behave like a sales machine, not a catalog. Then in year two we unlocked the full Google ecosystem.

The year-two move, Performance Max

In year one we plowed through Search. In year two we put Schrack's products across every channel at once, YouTube, Display, Discover, Gmail, and stopped waiting for buyers to find us.

The standout layer

Retargeting: the reminder that pays.

In electrical supply, decisions are rarely made in a split second. We quietly brought back everyone who browsed but didn't check out, a "second call" that turned hesitation into revenue.

Two years in, what stands out is the dedication and flexibility. As a company with an already developed market, we were genuinely surprised by the potential their work uncovered, especially the retargeting layer that nobody had touched.
