When you see an ad on TV, a sponsored post in your social media newsfeed, a billboard from the highway, or a price discount on the shelf, do you ever wonder how the advertiser decided to place those ads, and whether they actually work to drive purchases?  If you work at Nielsen, you can help advertisers understand the answers to these very important questions and inform their strategies going forward. Globally industry spends ~$600B on advertising and you can become part of the team on a mission to measure & improve the efficiency of every single dollar of that spend translating into $60B+ in value.

You’ll use advanced statistical models and the most robust data available to tease out the impact of marketing activities and simulate the impact of future budget changes, to help advertisers decide how much to spend on marketing, and in what ways, to maximize the impact of their spend.
