Facebook Comment Auto-Reply: Answer and DM Everyone Who Comments on Your Page (2026)

Your Facebook Page probably gets the same three comments under every post: “price?”, “link?” and “details please”. Each one is someone ready to buy, and each one waits until you get around to opening Messenger.

Facebook comment auto-reply fixes that. Someone comments, and within seconds they get a public reply under their comment and a private Messenger message with the link. This guide covers how it works, what Meta allows, and how to set it up from your phone.

How Facebook comment automation works

Three pieces, all through Meta’s official Graph API:

1. The comment. Someone comments on a post on your Facebook Page. Personal profiles and groups aren’t covered by the API.
2. The public reply. Optional: a short line under their comment — “Sent you a message, Priya! 📩” — so everyone scrolling sees that comments get answered.
3. The private reply. One Messenger message to that person, with what they asked for: a link, a price, a size chart. Meta allows one private reply per comment; when they write back, it’s a normal conversation.

You choose what triggers it:

• A keyword — only comments containing your word, like PRICE or LINK. Best when your post says “comment PRICE and I’ll send it”.
• Every comment — everyone who comments gets answered. Best for giveaways and launch posts.

What you can send

	On the Free plan	On paid plans
Public reply under the comment	✓	✓
Private Messenger reply with your words and link	✓	✓
Up to 3 link buttons under the message	✓	✓
Picture card (image + headline + buttons)	—	✓ Creator and up
Ask for their email or phone	—	✓ Creator and up
Any post / your next post (instead of one post)	—	✓ Pro and up

Two things that work on Instagram but not on Facebook: the follow check (Meta only exposes it on Instagram) and the “tap to get it” step before the DM.

Set it up in yudochat (about a minute)

1. Install yudochat from Google Play or the App Store and sign up free.
2. Connect Facebook and log in with the Facebook profile that manages your Page. On Facebook’s screen, keep only the Pages you want automated ticked.
3. Tap +, choose Facebook, and pick the post.
4. Choose “Only comments with my keyword” and type the word (PRICE), or choose every comment.
5. Write the private reply — what they asked for, plus your link under “Your link”. Add a short public reply if you like.
6. Go live. Test it by commenting your keyword from a different Facebook account — comments from the Page itself are ignored.

New to the builder? The 90-second setup video walks through every step (shown on Instagram — Facebook’s builder is the same).

Replies that sound like you, not a bot

• Use their name. {{username}} becomes the commenter’s name automatically.
• Write a few versions. Add up to five versions of the same message; each person gets one at random, so your comment section doesn’t look copy-pasted.
• Answer the actual question. If the post invites “price?”, the private reply should contain the price, not “DM us”.
• Keep the public reply short. The real answer lives in Messenger.

yudochat also sends each person at most one private reply per post every 30 days, so someone who comments five times doesn’t get five messages.

Facebook vs Instagram automation

If you run both, set them up side by side — same keyword, same message — and every lead lands in one Leads list, sorted Hot or Warm by what they wrote. See the Instagram comment-to-DM guide for what’s different there (follow check, story replies, DM keywords), and YouTube comment auto-reply if you post videos too.
