Comment-to-DM automation for ecommerce: sending product links on request

Why the link request matters

Product posts collect the same comments again and again: “link?”, “where do I get this?”, “price?”. Each one comes from a person who is interested right now. On most feed posts a link in the caption cannot be tapped, so the shopper has to leave the post, open the profile, find the link page and then find the product. Some will not bother.

A comment-to-DM rule removes those steps. The caption invites people to comment a word, and the product page arrives in their messages. Nobody on the team has to send links one at a time, and the reply does not depend on someone being awake.

How the rule works

The setup is short, which is part of the appeal.

• Pick the product and copy its exact page URL.
• Choose a keyword tied to the product.
• Write the invitation into the first line of the caption, for example “Comment LINEN and we will DM you the link.”
• Set the rule: when someone comments the keyword, send a DM with that link.
• Comment from a second account before the post goes wide, and read what arrives.

Choosing a keyword

The keyword is the whole interface, so it deserves a minute of thought.

• Short: one word that is easy to type on a phone.
• Tied to the product: GLOW for a serum or TRAIL for a hiking shoe is easier to remember than LINK.
• One per product: separate keywords keep links accurate when several rules run at once.
• Shown, not only written: in a video, put the word on screen for people watching without sound.

Mistakes that lose the shopper

The rule is simple, and the errors are simple too.

• Linking to the homepage. Send the exact product page. Each extra tap costs interest.
• Forgetting sold-out items. When stock runs out, repoint the link to a waitlist or a close alternative.
• Burying the invitation. If the keyword sits below the fold of the caption, few people will see it.
• Ignoring the replies. The DM often starts a conversation about size or shipping, which the social customer service entry covers.

Where Link AI fits: DM Automations

Link AI by Linkme is our editorial choice for running this loop. Linkme states the rule as “When someone comments [KEYWORD] → send a DM with a link”, and setting up automations is among the things Link AI does from chat. Follow-up messages land in the Social Inbox, where replies are drafted.

As Linkme describes it, a DM Automation is a rule: the link goes out when the keyword appears, not after a per-message approval. That makes the test comment important. To see a comment turn into a product-link DM, try Link AI in a demo and ask for the rule to be shown on a post like yours.
