Boosting your poll with a promoted post is a great practice to increase its visibility. This lets you target a specific audience and reach people outside your immediate circle of fans and friends. But how can you track your campaign performance and know how many people actually answered your poll as a result of seeing your ad? How can you re-engage with participants in order to promote your business?
The answer to both these questions lies in the Facebook Pixel. The pixel allows you to track participants so you can assess the effectiveness of your ad campaigns and then target these same participants as a Custom Audience in your next campaigns.
