The strategic tag
Names mentioned in the post, with a notification attached. The mention does not cite the people: it summons them.
If the post says nothing about the people it tags, the mention is not citing them: it is using them.
What holds, and what does not
The technique itself is neutral. What changes is the gap between what the line promises and what the post delivers.
Tag the people the post actually talks about, and say what they do in it.
Ask yourself, before tagging, whether the mention serves the person or only the post.
Prefer a private message when the content concerns only one person.
Do not tag ten large-audience accounts in the hope that one will reply.
Do not delegate the distribution to readers with "tag someone who needs this".
Do not cite someone solely to reach their network: the person sees it, and so does their network.
Three markers
The post says nothing about the tagged
The names appear, their work does not. Nothing in the text justifies each mention in particular: the list is interchangeable.
The list is long and well chosen
Five, ten mentions in a row, often accounts in the same sector with large audiences. The selection criterion shows.
The tagging is sometimes delegated
"Tag someone who needs to read this": the reader becomes the channel. Each comment adds a notification the author did not have to send.
The same mechanism, three forms
« Tagging 10 people whose content inspires me: @Sophie, @Karim, @Julie… »
The compliment justifies the mention. Each tagged person receives a notification, and their audience an invitation to come see the post.
« Tag someone who needs to read this today. »
The author delegates the identifying to the readers: each comment produces a notification and one more potential reader.
« @Marie, @Thomas, you live this every day, what do you think? »
The question gives the mention a form of politeness. The reply expected from the tagged relaunches the post in their own network.
The mechanism
The mention converts a post into notifications: each tagged person receives a personal alert, the only channel that escapes the feed's sorting. The post no longer asks to be seen; it is delivered, by name, to chosen recipients.
Being tagged creates a soft obligation. Ignoring a public mention is visible; replying, thanking or reacting is the cheapest way out. And each reaction from the tagged exposes the post to their own network, which was the real object of the mention.
The first hours decide a post's distribution. The interactions of the mentioned people arrive fast, and from accounts often better endowed with audience than the author's: the tag works as an assisted start, whose cost is paid by the tagged.
Four questions
People tagged to widen the reach.
An honest tag cites someone the post talks about, whose work it picks up, or from whom it expects a specific expertise. A reach tag cites an audience.
Look for what the text teaches about each person cited. A list of names with no attached content is a list of notifications.
"This made me think of you" is said in private. Saying it in public is choosing the witness over the recipient.
If the list mostly gathers large-audience accounts from the same sector, the selection criterion was probably not the content of the post.
The neighbors
The name-dropping
The same audience borrowing, with a notification added: the cited name becomes an alerted name.
The keyword comment
"Tag someone" manufactures comments like the keyword does, with one notification per comment.
The bait job posting
Hiring announcements ask for the same tag to reach the readers' networks.
Tag the people you write about, and say what they did.
