The keyword comment
A required word to leave in the comments to receive a resource in private. The document is the pretext; the comments are the objective.
If the document existed as announced, a link would be enough. The keyword does not trigger a sending: it triggers the algorithm.
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.
If you write, put the resource where it can be read without a counterpart, and say in one line what it contains.
If you offer to send it in private, stick to the sending: the resource first, nothing else unless the reader asks.
If you announce a limited number of sendings, apply it, and say why the limit exists.
Do not present as a service to the reader a device that primarily serves the post's distribution.
Do not promise a "complete guide" of which you show neither the table of contents nor an excerpt.
Do not use the resource as a gateway to an offer that was announced nowhere.
Three markers
A word in capitals, in quotes
"GUIDE", "AUDIT", "PDF". The word is short, visual, and has no other role in the post than to be copied.
Delivery happens in private
The resource is neither attached, nor linked, nor summarized. It travels through the inbox, the only place where the exchange can continue after the sending.
The resource stays vague
A "complete guide", a "detailed method", a "template". No table of contents, no page count, no excerpt: the value is declared, never shown.
The same mechanism, three forms
« Comment "AUDIT" and I'll send you the details. »
The post describes a problem, the solution is withheld. The comment is presented as a formality; it is in fact the price.
« I'll send it to the first 100 people who comment "TEMPLATE". »
The cap adds urgency to the trade. Nothing lets you verify the counter, or that the sending stops at the hundredth.
« To save you the search, comment "LINK" and I'll send it to you directly. »
The detour through the inbox is presented as a time-saver for the reader, when a link in the post would be shorter.
The mechanism
The comment is the interaction the platform values most. Each keyword dropped redistributes the post into the commenter's network, who becomes a relay without having said anything about the content. A hundred identical comments weigh more than a long debate under another post.
The trade then moves the relationship into the inbox. A public comment commits little; a private message opens a direct channel, often automated, where the promised sending can be followed by something else. The resource serves as an opener.
The required word has no sorting function: any comment would have allowed the sending. Its function is to standardize the replies so a tool can detect them, and to make the volume visible. A queue of identical comments is also a display: it shows, under the post, how many people wanted the resource.
Four questions
A resource traded for reach.
Look for it on the author's profile, site, or previous posts. If it only exists in the inbox, the trade is the condition, not the convenience.
If the resource arrives alone, the trade was honest. If it arrives with a meeting proposal or an offer, it was the pretext.
Reread the post ignoring the final promise. If only a problem description remains, the whole text served the trade.
A device repeated identically, with different resources, describes a collection machine more than a one-off share.
The neighbors
The dated urgency
The sending quota or the time limit adds the accelerator to the trade.
The disguised call to action
The same arrival channel: the private message presented as a service to the reader.
The link in the comments
The same trade-off: preserving the post's distribution by moving what would curb it.
Post the link: it costs you less than a keyword.
