Step 1

The Challenge

In August 2018, we took over performance marketing for JOIN.com. The goal was to develop an effective strategy to acquire a high volume of new customers via Google Ads. Initially, the campaign performed well, but after several months, both cost per acquisition (CPA) and cost per click (CPC) increased — significantly reducing campaign efficiency.

Rising CPC and CPA

After early successes, costs increased, threatening campaign profitability.

Negative trends in the campaign funnel

Some keywords that had performed well initially began generating significantly higher click costs without corresponding conversions.

Need for optimized bidding strategies

The challenge was to identify the root cause of the declining efficiency and restore performance through targeted bidding strategies and structured tests.

Step 2

Our Approach

To counter rising costs and declining performance in JOIN’s Google Ads campaigns, we developed a structured strategy focused on hypothesis-driven testing and optimization of bidding strategies. The primary objective was to reduce the cost per acquisition (CPA) and cost per click (CPC).

Formulating hypotheses & campaign testing

Testing with Google Ads Experiments: We used Google Ads’ testing tool to determine whether the focus on upper-funnel keywords was responsible for increasing CPCs and CPAs.
Shift to lower funnel: When initial tests showed no significant improvement, we shifted focus to lower-funnel optimization to improve conversion efficiency and increase conversion rates.
Data analysis & validation: The tests and resulting hypotheses enabled deeper insights and precise identification of problem areas.

Testing and adjusting bidding strategies

Switch to Target CPA: Since early tests did not improve performance, we switched the bidding strategy to Target CPA to optimize bids in real time toward a predefined CPA goal.
Targeted adjustments: This shift made it possible to generate conversions at the desired CPA and provided stronger control over campaign performance.
Results after 3 weeks: Within three weeks, CPA decreased by 33% and CPC dropped by 19%, significantly improving overall performance.
