Tutorial

Your First Comment Keyword Trigger on Instagram

First-time setup guide: choosing a post, testing triggers, public replies, and the checklist we use before turning an automation live.

April 28, 2026 · 2 min read · Liffio Team

Start with the right post

Do not test on a dead post from six months ago. Pick something recent with normal comment activity, or post fresh content this week with a clear CTA in the caption and video.

Pin a comment from your own account that shows the keyword in writing. Example: "Comment LINK and I will DM you the shop list."

Turn off the automation on old posts when the offer expires. Nothing confuses people faster than "here is the Black Friday link" in March.

Create the trigger

In Liffio, go to Automations, choose Comment, select the post, and set the keyword to LINK in all caps if that is what you say on camera.

Decide case sensitivity. Usually you want insensitive matching so Link and link both work.

Set the public reply to something short. Creators often use "Check your DMs" or "Sent." Keep it friendly, not corporate.

Test like you are a follower

Use a second Instagram account or ask a teammate. Comment LINK on the post.

Wait the full delay you configured. Do not assume it failed at five seconds.

Confirm the DM arrived, the link opens on mobile Safari or Chrome, and the public reply appeared under the comment.

Delete the test comment if you want a clean comment section before ads or boosts go live.

Go live checklist

Caption mentions the keyword verbally and in text.

Offer in the DM matches the offer in the video.

Link works while logged out.

Delay is at least 10 seconds.

You have inbox notifications on so real questions get human answers the same day.

Frequently asked questions

What if someone comments the wrong word?
They will not get the automation. Reply manually if it is a close typo, or add a second keyword trigger for the common misspelling.
Can I change the keyword after posting?
Yes. Update the automation, then edit the pinned comment and the spoken CTA in the video caption so everything matches.
