How to Use the Word LINK to Send Automatic DMs on Instagram

To have Instagram send a DM automatically when someone comments LINK, you create a keyword automation on the post, set LINK as the keyword, and put your URL in the message. The word LINK is popular because it is short, obvious, and tells the viewer exactly what they will receive. Viralyze handles the matching and sends the DM in about a second, with click tracking built in so you know how many of those comments turned into visits.

This article explains why LINK works so well, how to write the caption and the DM, and when to use a more specific word instead.

Why does the word LINK convert so well?

Because it removes every decision. The viewer does not need to know your product name, remember a code, or find your bio. They type four letters and the thing they wanted shows up in their inbox.

It also creates social proof in the comments. A thread full of people typing LINK tells new viewers that the offer is real and other people want it.

How do you set up the LINK keyword?

In Viralyze it is a one-minute job:

1. Create an automation and pick the post or reel. 2. Add "LINK" as the keyword, and add "link pls" and "link bhejo" as extra spellings. 3. Write the DM and paste your URL. Smart links track clicks automatically. 4. Switch on the public reply if you want "Sent you a DM 💌" under each comment. 5. Test with a sample comment and go Live.

Matching ignores capitals, so "link", "Link" and "LINK" all trigger it.

What should the caption say?

Say the word and the reward in one line. A podcast host promoting an episode might write: "Comment LINK and I'll DM you the full episode." Mention it in the reel audio too, because many people never read the caption.

Keep the rest of the caption focused on the content. The call to action should not compete with three other asks.

What should the DM say?

Two lines at most, with the URL in the first. For the podcast example: "Here is the episode you asked for. The part about pricing starts at 14 minutes." Then the link.

Viralyze applies AI variations so the DM reads slightly differently each time, and it replies in Hindi or Hinglish when the comment was written that way.

When should you use a different word than LINK?

Use a specific word when one post has more than one thing on offer. If the reel mentions a course and a free checklist, LINK is ambiguous. "COURSE" and "CHECKLIST" as separate keywords with separate replies solve that, and they also tag each contact by what they wanted.

Use a specific word as well when you want the keyword to double as a filter. "PRICE" attracts buyers; LINK attracts everyone.

How do you know how many LINK comments became clicks?

Open the automation funnel: comments, matched, delivered, clicked, signed up. The gap between delivered and clicked is the DM's job; the gap between comments and matched tells you whether you missed a spelling.

Every clicker is saved as a contact with the post as their source, and the home screen shows link clicks across all automations for 7, 30 or 90 days.

Frequently asked questions

**Will LINK trigger if someone writes it inside a longer sentence?** Yes. A comment like "can I get the link please" contains the keyword and will match.

**Can I use LINK on every post I publish instead of one at a time?** Yes. Choose the "any post" trigger and the LINK keyword will apply to each new post automatically.

**What if someone comments LINK on an old post after the offer has ended?** Set an auto-pause by date or number of DMs so the automation stops on its own, or pause it manually from the app.
