Keyword triggers: choosing words people will actually comment
The keyword is the entire interface of a comment-to-DM flow. Nobody reads the instructions under a post twice. A good keyword is something people type without thinking, that nobody writes by accident, and that makes the reward obvious.
Three properties of a good keyword
- Short and easy to type
One word, no special characters. On a phone keyboard, every extra letter is a reason not to comment.
- Unlikely in normal conversation
LINKorGUIDErarely appear under a post by accident. Words likeyesorloveshow up constantly and fire DMs nobody asked for. - Tied to the reward
CHECKLISTtells people what arrives.YEStells them nothing.
Exact match or contains
Most tools let you choose how a comment is compared with the keyword. That choice matters more than the word itself.
| Matching mode | Triggers on | Good for | Risk |
|---|---|---|---|
| Exact match | Only the keyword itself, such as guide | Posts with a very clear call to action | Misses comments like guide please |
| Contains | Any comment that includes the keyword | Casual commenters who add words around it | Also fires on this guide is wrong |
A practical default is contains matching with a distinctive word. The distinctiveness does the filtering, so you can be lenient about extra words around it.
Case, spelling and emoji
People type Link, LINK and link. Treat matching as case-insensitive. Common misspellings are worth adding as extra triggers for the same flow, for example CHECKLIST and CHEKLIST.
Say the keyword in the post
A trigger nobody knows about never fires. Put the keyword in the caption and, in a video, say it out loud and show it on screen. Make clear what arrives and where.
- 1Name the reward
Say exactly what people get, not just that there is something.
- 2Show the keyword
In the caption, ideally in the first line, in capital letters.
- 3Set the expectation
Tell people the message arrives in their DMs, so they know to check their inbox.
One keyword per post
When a single post advertises several keywords, people guess, mistype or pick the wrong one. Keep one keyword per post. If you run several offers, give each its own post. It also keeps your results readable, as covered in what to measure.
Frequently asked questions
In the caption, yes, because capitals stand out. For matching, treat comments case-insensitively so guide, Guide and GUIDE all work.
Yes. Adding common misspellings of the same word is a good use of that. Different offers are better off in separate flows.
Use contains matching with a distinctive keyword. The word does the filtering, so extra text around it does not matter.
