The Client

The Client is a financial institution with locations throughout the Southeast, providing a wide variety of deposit, lending, and investment products to individuals and businesses.

The Objective

Our goal was simple: test one of Google Ads’ automated bidding strategies to increase credit union applications.

Paid Media Strategy


    The problem

  • Since launching in early 2023, the non-brand ‘credit union’ campaign received clicks and impressions, but rarely resulted in an application submission.

    The conventional wisdom around automated bidding strategies, like max conversions, is that the campaign needs at least 30 conversions in 30 days to have enough data to work effectively.

    Therefore, how can you adopt an automated bidding strategy that needs conversion data to get conversions for a campaign that won’t convert?


    The solution

  • Create an experiment to see if max conversions can work on a campaign that historically has little to no conversion data.

    We did a 30 day split test: Enhanced Cost-Per-Click (ECPC) vs. max conversions.

    After 30 days, the max conversions test resulted in a 450% increase in conversions with an 83% decrease in cost per acquisition.


    Why it matters

  • Since implementing the new bidding strategy, the campaign has increased applications 628.57% as compared to the previous time frame.

This graph shows the growth of applications, as well in the decreased CPA, after the max conversion automated bidding strategy was implemented.


As the largest credit union in the Southeast, the Client wants to grow applications of new memberships, in which the customer must open a checking or savings account with a minimum deposit, and loan products, like personal loans, credit cards, and mortgages.

One campaign, targeting non-brand “credit union” keywords, was generating very few conversions since its launch in early 2023. Consideration was given to trying an automated bidding strategy; however, the conventional wisdom in the PPC community has maintained that a campaign needs at least 30 conversions in 30 days in order for an automated bidding strategy such as max conversions to have enough data to perform.

A 30 day experiment was created to test whether or not max conversions could work on a campaign with a lot of clicks and impressions, but very few conversions. The traffic was split evenly between the two bidding strategies: eCPC bidding vs max conversions.

In the 30 day timeframe of the experiment, the max conversion test saw a 450% increase in applications over eCPC, with an 83% decrease in cost per acquisition. After applying the experiment and taking a longer time frame comparison, applications increased 628.57%.
