You can keep track of your boosted content in your Boost Console, accessed via the dropdown menu associated with your avatar icon. Here you can track the status of your newsfeed Boosts, sidebar Boosts, and any offers you have sent or received for Channel Boosts.
Boost completion time varies and is a function of our Boost backlog and site activity. Typically we try to have boosts out within 24 hours, but these sometimes may take longer.
