Your Facebook Business Page’s Activity Log
Access the Activity Log for your Facebook business Page by clicking Edit Page and then Use Activity Log from your Admin panel. The Activity Log shows everything that happens on your Page from the time you started it. You can see all the Photos, Comments, Posts by Others, Spam, and more listed chronologically.
You can scroll through the posts or skip to a certain time frame by clicking on the date on the right (although that feature doesn’t always work that well). You can filter what you are looking at by clicking the selection on the left sidebar.
If you have scheduled posts, you also find those posts here so that you can edit them or delete them.
Notice that you can view Spam from the Activity Log. You regularly should check this section to see whether any posts are being “accidentally” marked as Spam that you want to allow on your Page. To unmark a post as spam, click the “circle with the line through it” symbol that appears to the right of the Post.
A drop-down menu appears where you can select Unmark as Spam. Now the post appears on your Page, and you can answer it as your Page.
