The Question:

If I have 14 Campaign Types in my Marketing Mix how much should I spend on each channel to maximize my return?

The Brand:

The company sells shipping for eCommerce businesses.

It basically allows the eCommerce business to buy cheap shippings that deliver a better service for the end client compared to the rest of the shipping suppliers here in Italy.

The Challenge:

As a business born and raised during covid had an incredible boost in growth that made the company more than double its marketing investments.

From investing just on google search, started investing on Facebook, programmatic, bing, youtube, display, performance max, etc.

After multiple conversion lift experiments we noticed that the attribution was broken, 60% of the conversions went into a “Direct” Source.


How can you plan your advertising budget if you can’t know what ROI got in the past?

How Can I better allocate my advertising budget to experience incremental sales?

The solution:

The marketing team leveraged Cassandra MMM tool to evaluate the performance of the past investments discovering what real ROI got each channel

Other than historical attribution, Cassandra analyzed and created diminishing returns curves for all the advertising channels.

These Diminishing returns told the marketing team what was the breaking point at which each investment started to become inefficient.

After an initial analysis, the marketing team used the Cassandra Budget Allocation tool to double-check their budget distribution hypothesis.

They asked the model to predict what to spend on each channel for the next two weeks and the model told the marketers to reduce the Meta advertising budget and allocate it to google search and google video.

This new allocation would’ve increased their conversions by 5.5% compared to the previous period

The distribution is implemented

The Results

After two weeks we double-checked the results.

We experienced a 5.75% increase in the number of conversions compared to the previous period

Cassandra refreshed its model on the new data and gave a new budget allocation for the following two weeks.

Cassandra suggested:

“Lower your budget by 12% on Google Search ads and reallocate 8% to google discovery & 4% to Meta “

This new change would’ve increased our total number of transactions by 6.6%

The distribution has been implemented.

After another 2 weeks, we double-checked the results and we experienced a + 7.6% in the number of transactions

Summary of the results

In 1 one month and one week, just modifying the budget distribution we’ve been able to obtain:

  • +13.36% in the number of transactions

  • +42.21% in profit

  • +22% in ROAS

  • -7% CAC (thanks to an additional Geo-lift experiment)
