Announcements — and why they're off
When the Evidence Engine publishes something for a site, it can announce it on LinkedIn or your Google Business Profile. Both are off until you turn them on, per project.
Why they're off by default
Because connecting an account for one purpose should not volunteer it for another. Posting to somebody's professional feed, publishing under their byline, or putting an update on their public business listing are three different things to agree to, and agreeing to one says nothing about the others — so each is a separate choice.
Turning one on
Open the project's Manage page and find "Announce what we publish". Each surface states the volume before you choose, not after: • LinkedIn — at most one digest post a day: what went live and why, with one link. Not a post per page. • Google Business Profile — at most one post per location per day, and never the same text twice within a fortnight. This belongs to the project because announcing is a property of the business — one LinkedIn page, one Business Profile — not of any one campaign. A campaign that named its own account under SmartStack → Settings keeps using it; this is what answers for every campaign, and for the gap-led loop, that never chose one. Nothing is ever announced that a stranger cannot open: the link is checked anonymously first. Everything we create in Drive is shared the moment it is made, so this almost never catches anything — but a share can fail, and when it does the announcement is held rather than posted as a link nobody can follow.
If your posts have stopped
That is this change, and it is deliberate. Google Business Profile posts used to go out through any connected account on the workspace, without anybody choosing it. They now need the same explicit opt-in LinkedIn has had since 14 August. Turn the project's switch on and they resume.
A feed is somebody's professional presence and a business listing is public. The channel is a guest there — which is why the limits are the offer rather than the small print.
