Overview
When a STEM education company wanted to reach new audiences, they contacted A-Train Marketing for a Google Ads campaign that yielded an exceptional “return on ad spend” and a sold-out product.
The Problem
Alongside a strong group of partners, SparkFun launched the Experiential Robotics Platform (XRP), which bridges the STEM education gap and provides a gateway into robotics through hands-on experiences and extensive educational content. The product resonated with the company’s market and enjoyed rapid adoption, but SparkFun wanted to capitalize on that momentum to amplify outreach efforts and connect with new audiences—including educators and parents—nationwide.
Leveraging insights from previous campaigns and SparkFun’s input, A-Train Marketing launched a robust Google Ads Performance Max campaign. The combination of innovative digital ads marketing strategy and advanced technology produced phenomenal results.
What Are Google Performance Max Campaigns?
According to Google Ads: “Performance Max is a goal-based campaign type that allows performance advertisers to access all of their Google Ads inventory from a single campaign. It’s designed to complement your keyword-based Search campaigns to help you find more converting customers across all of Google’s channels like YouTube, Display, Search, Discover, Gmail, and Maps.”
The Results Using Google Performance Max Campaigns
With A-Train Marketing’s guidance on strategy and execution, SparkFun’s campaign exceeded ROAS and revenue expectations. Not only did the product sell out, but the initiative generated tremendous awareness and interest in previously untapped audiences that will continue to help the company close the STEM education gap going forward.
In just three months, the Google Ads Performance Max campaign delivered these results:
4:1 ROAS in the First Month; 10:1 by the Third Month
$28,300 in Revenue From “Purchase Conversions”
More Than 380 Total Conversions and $0.62 CPC
