How Spanish ads reduced CPA by 20% and connected with a new audience

One of our clients was battling high frequency with prospective audiences and as a result, experiencing a deteriorating conversion rate. šŸ“‰

In this case study weā€™re going to unveil how we sorted these issues, opened up a new audience and reduced CPA by 20% šŸ¤‘! Veamos!

ā€

The problem

This client of ours (one of our favorites šŸ˜) had been running ads for over two years. The account had a decent budget šŸ’° and a relatively narrow audience. As a consequence the below started to happen:

ā€

At that point we were already using broad targeting in FB and IG, making use of all placements and refreshing the creatives every other week, butā€¦ that was just not enough! We needed a solution and we needed it quickly! ā²ļø

ā€

The research

The solution was going to come from finding segments from our audience who we still werenā€™t reaching with ads.

We got to work and started digging to find our precious solution! These are a few of the things we did:

  • Client and platform reps brainstorm
  • Creative and Growth team brainstorm
  • Keyword research and search terms analysis
  • Social listening

We started to see a pattern in each one of the researched steps. There was one ā€œsegment of the audienceā€ that kept getting mentionedā€¦Ā 

ā€

It wasnā€™t obvious to see it at the beginning because our images and videos were already culturally representative of the target audience but they were missing an important piece:Ā language representation.

ā€We needed to test Spanish-language ads!

ā€

The Solution

Having done the research, the solution seemed clear. Having ads in Spanish could reduce frequency as we would be reaching and engaging with a new audience and could bring performance back!

But, how do we test Spanish ads in an audience with Spanish and English speakers you askā€¦.Ā 

You can do that by using Multi-language ads on FB and IG!

ā€

Multi-language ads enable you to set up a single ad with multiple language variations and the platform matches the right language to the language users have set on their devices. Muy Ćŗtil!Ā 

ā€

Test Setup

We wanted to learn if Spanish ads on its own or multi-language ads performed better than English ads. To do so, we ran this test with the below A/B/C testing structure:

  • A: English AdsĀ 
  • B: Spanish Ads
  • C: Multi-language Ads (Spanish & English)

We started this initiative with Facebook, but weā€™ve now tested this on other platforms and with other clients. If you want to learn more about our testing methodology, reach out here :)

The Results

Now, to the happy part šŸ˜Š:

  • Multi-language ads (In English and Spanish) achieved a CPA 21% lower than EN ads
  • Spanish ads had a CTR 20% higher than English ads
  • Spanish ads were more affordable with lower CPMs
  • Frequency decreased with Multi-language ads and opened up to Spanish Speakers

It was great to see this revert back:
