Social media marketing allows our company to reach a large audience of potential customers, and to gain online presence on various platforms. Of these platforms, Facebook is the largest and has one of the most sophisticated marketing resources available. Due to the various marketing strategies available, it is important to identify which of these strategies and ad campaigns produces the highest conversion rates and provide the best return on advertising spend (ROAS). According to a recent study by Rakuten Marketing, digital marketers estimated that 26% of their marketing budget was wasted and spent on the wrong strategies and channels (Rakuten Marketing, 2018). By better understanding our target audience, ad campaign production, and ROAS, we can work towards creating efficient advertising campaigns that yield high results and maximize our advertising budget. Using historical data and data models, we look to identify the ad campaigns that result in the highest conversion, and those campaigns that result in a potential net loss. If successful, we can maximize our advertising budget, increase revenue, and grow our online presence on the largest social media platform in the world.
