Testing social media engagement for vaccine outreach
At CCL, we’ve been utilizing social media platforms to increase vaccination rates in Latino families based in San Mateo County, California. We’ve recently analyzed a bilingual ad campaign on Facebook and Instagram using three distinct messaging approaches, single-image ads and video content. Read what we learned about ad copy messaging and single-image ads here.
Our goals with social media were two-fold:
(1) gain insight into advertisements most engaging to Latino residents of San Mateo County, California, and
(2) identify whether Facebook or Instagram might lead to higher engagement levels, as measured by user clicks.
We’ve analyzed data from our testing that includes over one million impressions in the month of July 2021.
Our top-performing ad as measured by the most clicks from social media users across both Facebook and Instagram featured the following video:
The cost-per-click of the two video ads (featured here with slightly different ad copy) ranged from $0.69- $0.74 on Facebook. By comparison, the lowest-cost-per-click of the single image ads we ran in the two weeks prior had cost-per-click amounts ranging from $1.41-$1.55. Our video advertisement cost 50% less-per-click, which means our ad budget garnered 2X engagement when we switched to video.
Additionally, our video ads scored above-average engagement rankings, collecting far more comments, likes, and shares than any of our single image ads.
