Through the use of social listening, you need to first understand the affinities of your target market. You also need to look at the communities they are influenced by. Thirdly, combining the above with the topics they speak about will inform the motivational drivers of your segmented groups. This information can help you decide whether you need social ads, influencer marketing, banner ads, YouTube videos, etc. to not only get engagement from your community, but convert their engagement to an intent to purchase your product.
