# LinkedIn

> Post to your LinkedIn profile and the company pages you manage.

## Connect

Choose **LinkedIn** under **Settings → Channels → Connect** and sign in. Orbitwrite lists your profile and every page
you're an admin of, all ticked; untick any you don't want, then connect. Each becomes its own channel.

To add a page later, connect LinkedIn again: the list shows any you haven't added.

## What you can post

- **Text posts**, with the "…see more" point marked in the composer so you can see what shows before the fold.
- **Images**, up to nine, or **one video**.
- **A PDF document**, shown as a swipeable carousel. A document replaces other attachments.
- **Reshares** of an existing post, by pasting its link.
- **Mentions** of people and companies.

## Inbox, analytics and engagement

- **Inbox**: comments and mentions on company pages. LinkedIn doesn't let new apps read comments on a member's own
  posts, so profiles aren't included.
- **Analytics**: impressions, reactions, comments, reposts and clicks per post, video views on video posts, and
  follower history. A profile connected before Orbitwrite could read analytics needs reconnecting once.
- **Auto-engagement**: a first comment from the posting account. LinkedIn's terms treat automated likes, reshares and
  comments from other accounts as artificial engagement.

Company pages have the same limits.

## Good to know

- **Outside links reduce reach.** Many teams put the link in a first comment instead, with auto-engagement.
- **Ideal length.** LinkedIn's guidance favours posts of 1,200 to 2,000 characters; the
  [post score](https://orbitwrite.com/docs/guides/composer/post-score) checks against it.
- **Page admin.** If you stop being an admin of a page, its channel needs reconnecting by someone who is.
- **Stored content.** LinkedIn lets apps keep comments for 48 hours after reading them; older inbox conversations are
  re-read from LinkedIn when you open them.
