Create Facebook content in the ContentMate planner, select the intended Page, and choose immediate or scheduled publishing. This guide explains the available formats, the wizard fields, and the differences between stored media, prepared uploads, and published posts.
Before creating content
The Facebook Page must be connected to the current workspace. You also need the appropriate workspace permission to create or publish content and Facebook authorisation to manage posts. Working analytics does not automatically mean the Page has valid publishing permissions.
Check the destination accounts for every post. If several accounts are selected, ContentMate creates publications for the respective destinations. Failure on one platform does not mean successful posts on other platforms have been withdrawn.
Choose the right format
| Format | Content supported in ContentMate | Important differences |
|---|---|---|
| Feed | Text without media, a single photo or video, or several media attachments | Optional first comment; text background when only Facebook is selected and no media is attached |
| Reel | Video | Prepare the single video intended for the Reel; no automatic first comment |
| Story | Image or video; multiple files are processed sequentially | No caption or first comment from the corresponding text fields |
Multiple Story files produce multiple Story items, not one automatically edited film. Arrange files in the intended order and review each one. A feed post with several attachments is also not an automatically compiled video.
Step 1: Account, format, and media
- Open the planner and choose New post.
- Select the account card for the intended Facebook Page. Deselect any additional accounts chosen unintentionally.
- Choose Feed, Reel, or Story.
- Upload media or select existing files from the media library. Leave this area empty for a text-only feed post.
- Check the preview, errors, and warnings for each file. Edited files are validated again.
Understand file types and sizes
ContentMate's current Facebook image validation accepts JPEG, PNG, BMP, GIF, and TIFF up to 10 MB. This does not mean every format receives the same treatment in every Facebook content type. JPEG or PNG is a straightforward choice for a photo; accepting a GIF does not guarantee animated playback.
The general Facebook video validation accepts MP4 and MOV up to 100 MiB, with detected durations between 1 second and 40 minutes. Passing that general check does not guarantee a 40-minute video can be published as a Reel or Story. The content type, upload route, and Facebook processing can impose further restrictions. Use short videos prepared for Reels or Stories and follow the specific error shown.
Video checks also assess resolution, aspect ratio, and frame rate. Recommendations are not always blocking errors. Red errors must be resolved before publishing; warnings flag possible presentation or quality issues. Cross-platform content must satisfy every selected destination's requirements.
Edit your media
Open a file through its preview to crop a photo or trim a video. Text intended to appear inside an image or video must be included in the media itself. The wizard's caption field does not add a text panel, link sticker, or Facebook music-library track to a Story.
Step 2: Caption and first comment
Write the caption for the feed post or Reel. Check paragraphs, links, hashtags, and the selected Page in the preview. When publishing to several platforms, use the offered platform-specific text options when Facebook needs different wording from Instagram.
The first comment is an additional action after a feed post is successfully published. It is separate from the caption and cannot appear before the post. Facebook Reels and Stories do not receive an automatic first comment. Put important information into the supported main content for those formats.
For a Facebook-only text feed post without media, the wizard offers a background selector. Adding media, changing the content type, or selecting another platform can make that option inapplicable and clear the background. The preview provides guidance; Facebook controls the final presentation.
Step 3: Set the publishing time
With scheduling disabled, the final publish action requests immediate publication. To choose a future time, enable Schedule post, select the date and time, and review the summary.
The input uses your local browser time zone. Team members in different locations refer to the same stored instant but may see different local times. For example, 18:00 in Berlin is not necessarily 18:00 for a colleague in London. Recheck the displayed local time when travelling or around daylight-saving changes.
Schedule large media with enough lead time. A request made seconds before the target leaves little time for transfer or Facebook processing. The scheduled time is not a guarantee that the post will become visible in Facebook's feed at an exact second.
Separate uploading, preparation, and publication
Media-library upload: The file is stored in ContentMate and can be reused. It does not create a visible Facebook post.
Preparation: ContentMate can prepare scheduled Facebook content in the background. Multiple feed attachments, Reels, and Stories have dedicated upload steps. Preparation differs by format: for a single feed video, it may initially make the source file available while Facebook retrieves it during publication.
Publication: ContentMate performs the publishing operation and handles the platform response. Facebook may still process the media afterward. Consequently, “file uploaded” does not mean either “post published” or “Facebook processing complete”.
You do not have to trigger those technical steps manually. Check the post's status in the planner, especially after the scheduled time. A short delay is not a reason to submit an identical second publishing request.
Step 4: Review and submit
Before the final click, check:
- the Facebook Page and any additional destinations;
- content type and media order;
- caption and optional first feed comment;
- date, time, and local time zone;
- validation messages and account permissions.
After scheduling, check the calendar entry. When it is published, use the platform link where offered to inspect the actual Facebook post. Editing an upcoming calendar entry differs from editing content that has already been published. See Calendar and scheduled posts.
Handle errors and partial results
| Situation | What to do |
|---|---|
| A media check fails | Read the specific file error, correct the file, and validate it again |
| Facebook reports missing rights | Check the Page and publishing permission; reconnect if necessary |
| The scheduled time has passed but processing continues | Check the status and allow processing to finish; do not submit a duplicate |
| Only some Story items appear | Check each item and the overall result before publishing the entire sequence again |
| The post is visible but its first comment is missing | Confirm it is a feed post and comment permission is available; do not republish the main post |
| Another platform succeeded while Facebook failed | Handle the Facebook result separately; successful destinations may already be public |
| Facebook rejects locally validated media | The platform response determines the outcome; check format, processing, and Page access |
For a support request, record the affected Page, scheduled time, content type, and visible error. For a multi-account post, identify which destinations succeeded. This helps distinguish a rejected upload from a delayed result or a separate first-comment failure.
