If hired for the sales position with GroupM, we may ask you to test different advertisements. Have you created split or A/B ads? What worked and did not work and why?

How to Answer
Example Answer
Community Answers

Occasionally our clients may want you to run split advertisements. Split, or A/B ads are two to three different ads for the same product. Both ads run simultaneously for short periods, after a few days, the ad with the best performance is kept and the money going towards the other one to two ads will be put towards the top performing ad. Alternatively, the same ad may run but targeted at different demographics.

Explain your experience with split ads, give specific examples. If you have never run a split ad, explain your knowledge of how they function.

"In my last position I created a split ad for a massage spa. I used natural and calming imagery for the A ad, and used colorful, bright imagery for the B ad. These were marketed to the same target demographic. After three days, ad A was performing 60% better than ad B. Therefore ad B was cut and the budget was put into the ad with better performance."
