Boost Post

Boost a post by submitting it to Facebook’s ad platform

Available on Premium, Business, Enterprise plans.

Boost an existing Facebook post to create an ad. This endpoint allows you to convert your organic posts into paid advertisements with custom targeting, budget, and scheduling parameters.

• Budget and bid amounts must be specified in USD with up to two decimal places.
• The ad must run for at least 30 hours to address the Facebook requirement.

• You can use the interests endpoint to find interest IDs for targeting.

• Facebook may take up to 24 hours to review and approve boosted posts.

• If using fbPostId directly (instead of Ayrshare postId), ensure it’s a valid Facebook post ID.

Ad Goals

Each ad must have a goal. The goal determines how the ad will be optimized for display.

• engagement: This goal seeks to increase engagement while ensuring that the ad reaches the maximum number of unique users. It balances visibility with engagement, showing the ad to as many different people as possible who may interact with it.

• interactions: Designed to boost interactions, such as likes, comments, and shares, on the ad. Facebook prioritizes showing the ad to users most likely to engage with it.

• awareness_views: Focuses on increasing brand awareness by maximizing the number of times the ad is displayed. It prioritizes showing the ad as many times as possible within the budget, regardless of unique reach.

• awareness_audience: Aims to enhance brand awareness by maximizing the number of unique people who see the ad. It ensures that the ad reaches as many different users as possible and maximizes the unique audience size rather than showing it multiple times to the same audience.
