Connect a LinkedIn profile or company page
With LinkedIn, you choose a target after connecting: your personal profile or a company page where you are an administrator. There is one target per brand.
Profile or company page: where should posts go?
You decide that once per brand. Both at the same time isn’t possible.
- Company page: Posts appear in your business’s name. You have to be an administrator of the page. The page is your business’s showcase and the place for job ads.
- Personal profile: Posts appear under your name. Based on experience, personal profiles often reach more people than company pages. That is a rule of thumb from the industry, not a statement from LinkedIn.
Example, a cleaning company: The company page holds reference projects and open positions. The managing director explains on her profile how a job is carried out. If you want to cover both, you create two brands, more in Team, roles and brands.
How to connect LinkedIn
You need the permission to connect accounts and an active plan. Who may do that is explained in Connect your first social media channel.
- Open Backstage. In the sidebar, click Backstage and then Connections.
- Click Connect LinkedIn. The whole page switches to the LinkedIn login, and no popup opens. Finish the process in the same browser.
- Sign in and confirm. Sign in to LinkedIn and confirm the permissions that are requested.
- Choose the target profile. Back in Backstage, you choose your personal profile or a company page under Target profile. The choices are pages where you are an administrator. companycore confirms with “Saved”.
After that, the card shows Connected. The target applies to the whole brand, and there is no per-post choice.
What you can post on LinkedIn
| Format | Media | Special notes |
|---|---|---|
| Feed post | 0 to 20 images, text-only too | Text up to 3,000 characters (LinkedIn Help). |
| Document | 1 to 10 images | companycore turns them into a PDF, and each image becomes a page. This is how the LinkedIn carousel comes about. The title is public. |
| Video | 1 video, 3 seconds to 3 minutes | The title is public. |
Through its API, LinkedIn offers a carousel as a post only as an ad (Microsoft Learn, LinkedIn Posts API, retrieved October 13, 2026). The Document format is therefore the way to a carousel.
The title is public for documents and videos
For Document and Video, LinkedIn shows the title on the post. If you leave the title field at the top of the editor empty, companycore builds it from the first line of text. Check it before you schedule.
- Mentions: Only company pages can be linked, via Link company… (up to 10 per post). People stay plain text.
- Options: Allow resharing and Allow comments, both on by default. Allow comments only appears if your connection has the necessary permission.
- Alt text: For images in the feed post, you add it under Image details.
All formats and sizes: Formats by platform. More on carousels: Carousels, slides and templates.
What LinkedIn takes into account, according to its own help
According to LinkedIn Help, which posts someone sees depends, among other things, on the topic, dwell time and whether a post offers knowledge or advice (retrieved October 13, 2026). For a cleaning company, that means: a post that explains what a maintenance cleaning includes and what costs extra gives the reader something. An image saying “We’re here for you” doesn’t. You can find ideas for your industry in Marketing for cleaning companies.
How long does the connection last?
companycore renews the LinkedIn access automatically. After 365 days, LinkedIn requires a new login. Before an expiry that can’t be extended automatically, companycore warns you 7, 3 and 1 day beforehand.
In some cases, the card additionally shows Renew connection now. You only see this as owner or admin and only if the function is available. After the click it says: “Renewed — valid until …”. More in Connection expired or disconnected.
Problems and solutions
| Message or state | What helps |
|---|---|
| The page is missing under Target profile | Check your role on the company page. The page reliably appears if you are an administrator there. If necessary, have an administrator of the page add you, and connect again. |
| “You lack the role to publish on this LinkedIn company page (Super Admin or Content Admin) …” | Your account doesn’t have the required role on the page. Have it assigned and schedule the post again. |
| “LinkedIn considers the text a duplicate of an earlier post — please change the text slightly and reschedule.” | Change the text slightly, for example the first line, and schedule again. This happens with identical repeats, for example a job posting that you publish regularly. |
| Badge No target selected | Choose a profile or a page under Target profile. Without a target, posts fail. |
| “Sicherheitsprüfung fehlgeschlagen. Bitte im selben Browser erneut verbinden.” (German; meaning: “Security check failed. Please reconnect in the same browser.”) | Start connecting again and finish it in the same browser. |
