One of the best features of Facebook advertising is its wide ad placement options which let advertisers choose the best area where they think their ads will perform best. Aside from having more freedom to execute creative ideas, this also gives advertisers better understanding on what type of ads work best for their audience.
While Facebook claims that choosing the automatic placement can give you the “lowest average cost overall,” it is still best to manually choose your placements if you have previous data on where your campaigns performed well. After all, there’s no one else who knows the performance of your ads better than you.
You also have to remember that not all facebook ad placements support every type of ad. The infographic below will guide you on the advantages of every type of Facebook ad placement and the ad types that they support.
