How to Automatically Send a Link When Someone Comments on Your Reel

To automatically send a link when someone comments on your reel, you attach an Auto-DM to that reel, choose a keyword, and paste the link into the message. From then on every matching comment receives the link privately, in about a second, without you opening Instagram. Viralyze does this through the official Instagram API, and it tracks every tap on the link so you know what the reel actually produced.

This guide walks through the practical choices: which link to send, how to phrase the caption, and how to read the numbers afterwards.

Why send the link by DM instead of in the caption?

Because Instagram captions do not have clickable links, and comments do not either. People who want your link have to leave the reel, open your profile, find the bio and then find the right link. Many of them never complete that trip.

A DM puts the link one tap away from the comment they just left, while they are still interested. That is the entire reason comment-to-link automation exists.

How do you set up the link DM?

Setup takes about a minute in Viralyze:

1. Create a new automation and pick "comments on a specific post". 2. Choose the reel. 3. Add a keyword. A Notion template seller might use "TEMPLATE" plus "template please" and "link pls". 4. Write a short DM and paste the link. The app's smart links track clicks automatically. 5. Test it with a sample comment, then set it Live.

If you prefer, you can attach a product checkout page instead of a plain link, so the DM leads straight to payment with 0% platform fee.

What should the caption say?

Tell people the exact word to comment and what they will get. "Comment TEMPLATE and I will DM you the free planner" works better than "link in bio" because it gives one clear action and one clear reward.

Say the keyword in the reel itself as well, as spoken text or an on-screen caption. People who watch without reading captions still need to know what to type.

Can you ask people to follow before they get the link?

Yes, with the follow-gate. When it is on, commenters who do not yet follow you are asked to follow first, with up to three polite nudges before the link goes out. People who already follow receive the link immediately.

Use it when growth matters more than speed. Leave it off for paid offers, where any extra step costs you sales.

How do you know the link is working?

Open the automation and look at the funnel: comments, matched, delivered, clicked, signed up. The gap between delivered and clicked tells you whether the DM copy is doing its job.

On the home screen, Viralyze also lists your top reels by DMs sent, so you can see which reel earned the most link requests and make more content like it. Each person who clicks is saved as a contact with the reel recorded as their source, and the list exports to CSV whenever you need it.

What happens if someone replies to the DM?

Their reply shows up in the Inbox with the original comment attached, so you have context without digging. Reply from the app or in Instagram within the 24-hour window Meta provides.

This is where sales often close: someone taps the link, has one question, asks it, and gets an answer the same hour.

Frequently asked questions

**Does the person need to follow me for the DM to arrive?** No. Instagram allows one private reply to any comment within 7 days, follower or not. The follow-gate is optional.

**Can I send a different link for a different keyword on the same reel?** Yes. Each keyword can have its own reply, so "TEMPLATE" can send the free planner and "PRO" can send the paid version.

**Will the link DM look spammy?** Each message is varied slightly by AI so it reads naturally, and the optional public reply, such as "Sent it to your DMs", is rotated too.
