# Auto-reply to comments   
on your Instagram and Facebook ads

You pay for every person an ad reaches. When one of them comments "price?" or your keyword, Reachlee answers publicly and sends the DM with your link in seconds, on the boosted copy as well as the original post. And when someone taps a Send message ad, your flow greets them and carries on the conversation.

## Can you auto-reply to comments on Instagram and Facebook ads?

Yes. When you boost a post or reel, comments on the promoted copy trigger the same comment-to-DM automation as comments on the original. Reachlee replies under the comment and sends one private message with your link, on Instagram and on Facebook Pages, through Meta's official API. For ads that open a chat, the ad click trigger turns the first message of a flow into the ad's greeting and continues when the person replies.

1Comments on a boosted post or reel fire your comment automation. On Instagram, Reachlee matches the promoted copy to the original post for you.

2Use the any-post trigger with a keyword so every post and every boosted copy is covered by one automation.

3For Send message ads, the ad click trigger makes your flow the ad's greeting in Ads Manager. Meta then allows 7 days to reply.

4Each comment can get one private reply, within 7 days of the comment. That is Meta's rule for every tool.

How it works

## Set up replies to ad comments.

01

### Create a comment automation

Pick the post or reel you plan to boost, or choose any post so future ads are covered too. Add the keyword people will comment, such as PRICE or LINK.

02

### Write the reply and the DM

Add a short public reply so other viewers see you answer, and the DM with your link as a button. Keep the DM to what the ad promised.

03

### Boost the post

Boost it from Instagram, Facebook or Ads Manager as usual. Comments on the promoted copy now get the same reply and DM as comments on the original. If you have no creative to boost yet, a generator for [AI UGC ads](https://www.adstellar.ai/features/ai-ugc-ads) such as AdStellar makes creator-style video ads for Meta.

## Why ad comments are easy to miss

When you boost an Instagram post, Instagram creates a second copy of it for the promotion. The app shows you one post, yet comments from people who saw the ad arrive on the promoted copy. An automation tied only to the original post can miss them. Reachlee maps the promoted copy back to the original post, so the comment fires the automation you already built. On Facebook, Meta delivers comments on a boosted Page post like any other Page comment.

* The any-post trigger covers every post, old and new, and every boosted copy, with one automation per offer.
* A specific-post automation also follows the boosted copy of that post.
* Ad commenters are usually new to you, so keep the first DM as text and a button with the link.

What's inside

## What you can send to people who comment on an ad.

The same steps as any comment-to-DM, working on paid reach.

01

### A public reply

A short answer under the comment, so the next viewer sees that asking works.

02

### The link in a DM

One private message with your link as a tracked button, so you can see how many ad commenters tapped it.

03

### A lead-capture question

Ask for an email or phone number in the conversation and save it as a lead before the link is sent.

04

### A reminder

One follow-up for people who got the DM and didn't tap, sent inside Meta's 24-hour window.

05

### A follow check

On Instagram, ask people to follow before they get the link, so paid reach also grows your audience.

06

### AI answers

Reachlee AI can answer open questions such as price, sizes or delivery from the knowledge you give it.

## Send message ads: the ad click trigger

Some ads don't ask for a comment. They open a chat. In Reachlee's flow builder, add the trigger for a click on an Instagram ad or a Facebook ad, and make the first step a message with quick replies. Set the flow live and its greeting appears in Meta Ads Manager under your automation's name. Choose it as the saved template when you build the ad. When someone taps a quick reply or types, the flow continues with the branch you drew.

* Available on Pro and above, for Instagram accounts and Facebook Pages.
* For Instagram, the account must be linked to a Facebook Page so the greeting shows in Ads Manager.
* After someone messages you from an ad, Meta allows up to 7 days to reply.
* Boosted posts don't use message templates. Create this kind of ad in Ads Manager.

FAQ

## Ad comment auto-replies, answered.

Does comment-to-DM work on boosted Instagram posts?

Yes. Comments on the boosted copy of a post or reel trigger the automation on the original post. Reachlee matches the two for you, and an any-post automation covers every boosted copy.

[Comment to DM automation](/use-cases/comment-to-dm/)

Does it work on Facebook ads?

Yes. Meta sends comments on a boosted Page post to the tool like any other Page comment, so a keyword comment gets a public reply and a private Messenger message.

[Facebook comment to Messenger](/use-cases/facebook-comment-to-messenger/)

Why did comments on my ad get no DM?

The usual cause is an automation tied to a different post. Switch the trigger to any post with a keyword so every post and every boosted copy is covered. Also test from an account that isn't the post's owner, because your own comments never trigger an automation.

[Why did my automation stop working?](/guides/why-did-my-instagram-automation-stop-working/)

Can I message everyone who saw my ad?

No. Meta lets a business message only people who engaged first, by commenting, replying to a story or sending a message. An ad comment or an ad tap counts, a view does not.

How long do I have to reply to an ad comment?

One private reply per comment, within 7 days of the comment. After the person replies or taps a button, you have 24 hours to continue the conversation.

[The 24-hour messaging window](/guides/instagram-24-hour-messaging-window/)

What is the ad click trigger?

A trigger in Reachlee's flow builder for ads that open a chat. Your flow's first message becomes the ad's greeting in Ads Manager, and the flow continues when the person answers. It is on Pro and above.

Which plan do I need?

A comment automation on one specific post works on the free plan. The any-post trigger, Facebook Pages and the ad click trigger are on Pro and above.
