LinkedIn

Buzzator publishes to both personal LinkedIn profiles and Company Pages. You can connect several Pages you administer — each becomes its own account you can post to — alongside your personal profile. This page covers the caption and media rules, and the one thing about LinkedIn "carousels" that trips people up.

Formats and limits

Setting Limit
Caption Up to 3,000 characters
Hashtags Up to 10
Formats Single post, document carousel
Document carousel Up to 9 pages
Video Up to ~5 GB, up to 10 minutes, MP4 only
Alt text Supported on images (not video)
Publishing rate About 100 posts per day

This is the big one. On LinkedIn, a carousel is not a swipe-through strip of images the way it is on Instagram — it's a document that readers page through, backed by a PDF.

Carousel = document, not image strip

When you build a LinkedIn carousel, Buzzator bundles your images into a single multi-page PDF and posts it as a document. LinkedIn renders that as a page-through carousel in the feed. The limit is 9 pages (one image per page), not the 10-slide image carousel you may know from Instagram.

If the document upload can't complete, Buzzator falls back to posting your images as a standard multi-image post so the content still ships.

Video

  • Up to about 5 GB, up to 10 minutes.
  • MP4 only — other video formats aren't accepted.
  • At most one video per post.

You can't mix media types in one post

A single LinkedIn post is either images-only, one video, or one document carousel — never a mix. If you attach an image and a video together, the post is rejected before it's sent.

Company Pages

Posting as a Company Page differs from a personal profile in a few ways:

  • The post is authored as the organization, not as you.
  • Page posts are public only — the "connections only" and "logged-in members" audiences apply to personal posts, not Pages.
  • Each Page you administer connects as its own account.

Everything else — caption length, hashtags, images, video, and the document carousel — works the same as on a personal profile.

Post options

  • Visibility (personal profiles) — publish to everyone (public), your connections only, or logged-in LinkedIn members. Company Page posts are always public.
  • Disable resharing — turn off the reshare button so others can't repost your update.
  • First comment — Buzzator can auto-post a first comment right after the post goes live, a common place to drop links.
