SOLARFROMZERO SOLAR DEMAND IN GERMANY

We launched a new German solar brand from zero and compared three controlled traffic campaigns instead of relying on one isolated result.

01 the challenge

ZERO HISTORY. EXPENSIVE MARKET.

The brand started with no followers, content or campaign history in a market where clicks are costly and solar decisions are slow.

02 our solution

THREE TESTS. CONTROLLED TESTING ONE TRAFFIC RANGE.

We separated commercial hypotheses, offers and creative formats, then compared three traffic flights on the same click-cost basis.

  1. 01

    BUILD THE BASE

    Prepared the profile, content system and campaign measurement.

  2. 02

    SPLIT SEGMENTS

    Separated investors, farmers and business owners.

  3. 03

    TEST OFFERS

    Matched messages to commercial use cases and objections.

  4. 04

    CONTROL CPC

    Compared each traffic test on the same click-cost basis.

  5. 05

    KEEP LEARNING

    Used the results to define the next acquisition hypotheses.

03 the results

what the tests proved

ONE MARKET. THREE COST BENCHMARKS.

Rather than present one isolated campaign, we compared three controlled traffic flights. All landed in a narrow €0.33–€0.38 CPC band, giving the new brand a planning range grounded in three tests. Measured directly in Meta Ads (Nov 2024–Mar 2025); we report clicks, spend and weighted CPC only — no leads, sales or ROI.

05 who this is for

BEST FOR TEAMS THAT NEED RESULTS.

For new brands that need a controlled traffic benchmark before deciding whether to invest in lead or sales campaigns.

  • You need a comparable traffic benchmark before choosing a solar offer or message to develop further.
  • You want a tested CPC range before you scale spend
  • You value honest reporting over vanity metrics

06 timeline

HOW THE SYSTEM WENT LIVE.

  1. Foundation

    We defined one question for all three tests: which offer and message could earn relevant link clicks at the lowest comparable cost?

  2. Build & ship

    Three separate traffic tests used distinct commercial hypotheses and creative formats.

  3. Compound

    We compared 2,276 link clicks and their weighted cost, without turning a traffic test into an unsupported lead or sales claim.

07 asked about this case

Was this a one-off campaign or a system?

A system: three traffic tests ran on the same cost basis from a cold start, and the results set a buy-range the brand can plan future traffic on.

Can a traffic test answer our question?

Only if the question is about reach or click cost. If you need leads or sales, the campaign and measurement plan must be designed for those outcomes.
