PULL QUOTE

“eMFORCE was able to produce highly effective feed ads, testing the performance of various video ad formats. As a result, the video ads in Instagram Stories performed well in terms of view and conversion rates. Users who saw ads in Instagram Stories were more likely to sign up for a credit card. Since the active user base of Facebook and Instagram matches our target audience, they were the optimal platforms for our campaign.”

Lee Yun Kyoung, Brand Strategy Department / Assistant Manager, KB Kookmin Card

 

“Inspired by the success of the campaign, KB Kookmin Card continues to advertise in Instagram Stories while maximising the effectiveness of advertising through retargeting users that viewed their Stories.”

THEIR SOLUTION

Putting ads to the test

To raise awareness of the new credit card among the target audience, eMFORCE used highly effective ads from existing Instagram Feed campaigns and improved them further for Instagram Stories.

 

The ads were differentiated by type of advertisement, ad copy, colour tone and themes. The campaign then A/B tested the different video ads in Instagram Stories for each gender and age, determining the ads with a high response and conversion rate for each.

The campaign encouraged Stories users to click-through by adding a ‘Learn more’ button and then retarget the ad viewers. Placing an ‘Apply now’ button in the retargeting ads helped to increase the conversion rate.

 

To ensure the campaign reached the right audience, eMFORCE targeted South Koreans aged 18-34, using Lookalike Audience, interest targeting and retargeting. The combination of interests and website visitor targeting helped to increase impressions and clicks. The campaign ran on Facebook, Instagram and Instagram Stories.
