Social posting

MeridianOS™ posts to five social networks: Facebook, Threads, LinkedIn, X and Bluesky. Posts are text with an optional link. You write them yourself or have MeridianAI write them for each network.

Each network has its own page, which you reach from the Integrations tab of Business Profile. Posts to Google itself are covered in Google Business Profile, reviews and listings.

The five networks and their limits

Each network posts to one place and has its own character limit and hashtag cap.

Network	Posts to	Limits
Facebook	Your Page	1,500 characters. No hashtags.
Threads	Your profile	500 characters. No hashtags.
LinkedIn	Your company page	3,000 characters. Up to 3 hashtags.
X	Your account	280 characters. Up to 2 hashtags.
Bluesky	Your account	300 characters. No hashtags.

Each network also handles links in its own way. When a post runs past the limit, it is trimmed at the end of a sentence, so it does not stop mid-word.

Connected listings and social profiles in MeridianOS — Connected listings and social profiles.

Before you connect

Connect Google first. Every network requires it. See Connect Google.
Stack Digital turns each network on for your site. Until then, that network shows Coming soon.
You need an admin login.

Connect a network

Open Business Profile and select the Integrations tab.
Open the page for the network you want.
Connect the network and pick the account to post to.

If a login expires or is revoked, MeridianOS™ detects it and explains what happened in plain language. The page gives you a Reconnect button and a help link.

What each network's page has

Once a network is connected, its page is where you do everything for that network.

Part of the page	What it is for
New post	Write a post, with Write it for me to have MeridianAI draft it.
Post automatically	Scheduled posts for this network, on a schedule of its own.
Waiting to post	Drafts that have not gone out yet.
Posted	The history of what went out. Each post has a link to see it on the network, for example View on Facebook.

Write and send a post

On the network's page, select New post.
Write the post yourself, or select Write it for me.
Post it, and confirm when asked.

Posting right away always asks you to confirm first.

Post automatically

Post automatically has MeridianAI write posts for a network on a schedule. Every network has its own schedule and its own approval switch, so you can run each one differently.

Option	What it does
Post without approval	Off by default. While it is off, automatic posts wait for your approval before they go out.
Add a link	Adds an optional link to posts.
Hashtag count	How many hashtags a post carries, within the network's cap.
Extra instructions	Your own notes that steer what MeridianAI writes for this network.

Automatic social posts wait for approval by default. They go out on their own only after you switch on Post without approval for that network.

How MeridianAI writes for each network

Each post is written for that network's own style and length, so two networks do not get an identical post.
MeridianAI avoids repeating your recent posts.
When a network limits how fast posts can be sent, MeridianOS™ retries automatically.

Write it for me and automatic posts need MeridianAI set up on your site. Stack Digital turns this on for your site.
