Ads, in the same comment start
There is no separate ad trigger to learn: the comment start narrows to ads in one choice.
Ads in the same start
The comment start covers ads; one choice narrows it to them.
- Ads onlyOnly comments on ads
Comments on your Facebook and Instagram ads start the flow; organic posts and reels do not.
Facebook sends an event for every comment on an ad post, and Instagram marks an ad’s comments with its ad id.
- Any post or adAds and posts together
One flow for every comment on the account, ads included.
- Posts and reels onlyKeep ads out
The opposite case: run a separate flow for ads, or none.
- Dark posts included
An ad’s own post that never shows on your feed counts as an ad. To run a flow on one dark post, paste its link in On which posts.
Ads never appear in the post list, so a dark post is picked by its link.
What the ad buyer sees
The same keywords and modes as any comment start.
- Has a keywordprice, how much, cost
Up to 50 keywords, capitals and accents ignored, in any language.
- Any commentEvery comment on the ad
Every commenter gets the private reply, once per person if you choose.
Meta allows one private reply per comment, within 7 days.
- Spam first
Your moderation rules run before the flow, so a scam comment under the ad is hidden or deleted and never gets your DM.
Answer the ad, then the buyer
A reply under the ad for everyone reading, the details in a DM for the person who asked.
Start from comment to DM or keep a separate flow on Ads only next to your post and reel comments; inside one flow, a condition with Commented on an ad sends ad comments their own way. A public reply shows the next reader an answer, the private reply takes the buyer to DMs, and a question there can collect their email or phone.
Ads only, in the app
One choice on the start, on Facebook and on Instagram.
- Ads only
- Comments on ads start it; posts and reels do not.
The rules for ad comments
The same private reply rules as any comment, with Meta’s notes on ads.
| What | The limit | Set by |
|---|---|---|
| Events for ad comments | Sent for comments on ad posts (not for the ad posts themselves) | |
| Private replies per comment | One, within 7 days | |
| Instagram ad comments | Arrive with the ad’s id; Meta notes they may arrive twice, and the builder sends once | |
| Where it runs | Facebook Page ads and Instagram ads | CommentWatchDog |
| Instagram dynamic ads | Meta sends no ad id, so their comments may count as post comments and Ads only may miss them |

Ad comments, cleaned and answered
Spam under an ad is hidden before your DM goes out, on both networks, and a buyer who comments twice can be answered twice.

Questions people ask
Short answers before you start.
Yes. Start a flow with Someone comments and choose Ads only: new comments under your running Facebook and Instagram ads, dark posts included, get your public reply, your DM, or both, in seconds. Instagram dynamic ads are the exception: Meta sends no ad id for them, so choose Any post or ad to cover them.
Yes. Instagram sends ad comments with the ad’s id, and each comment can get one private reply, within 7 days of it. If they tap its button or answer it, the chat is open for the rest of the flow.
Yes. A condition with the rule Commented on an ad sends ad comments one way and post comments another, so one flow can cover both.
Yes. Add a Hide the comment step. Your moderation rules also run before any flow, so a scam comment they hide never gets your DM. To delete spam under ads, see hide or delete comments on Facebook ads.
No. Any post or ad covers ads and posts together; Ads only keeps the flow to ads. Both are one choice on the same start.
