# Instagram ad comment automation: answer "how much?" in seconds

Instagram ad comment automation sends a DM to people who comment on your sponsored posts. With ReplyRep, "how much?" under a paid post gets a price, a link and a code about three seconds later, while the person is still looking at the ad. It runs on Meta's official API and stops the warmest comments of your week from waiting for a person to get to them.

## What is Instagram ad comment automation?

You paid for the impression that made someone comment "price?" under your ad. That comment is a buyer raising a hand. If the answer arrives tomorrow, they have bought from someone else or forgotten why they cared. Ad comment automation answers it by DM straight away, with the product, the price and a reason to buy now.

It works like [comment to DM](https://replyrep.io/features/instagram-comment-to-dm), but on sponsored posts, which is where comments cost you money to get. Every unanswered one is ad spend that leaked.

## How does ad comment automation work?

1. **Your ad runs.** Comments come in from people who have never seen your account before.
2. **Someone comments a keyword.** "price", "how much", "link", "size": the words people actually type under ads.
3. **ReplyRep sends the DM.** About three seconds later, the price, link and code are in their inbox.
4. **Optionally, a public reply.** On paid plans, Comment Auto Reply answers under the comment too, so other viewers of the ad see that questions get answered.

## What does an ad comment automation look like?

**Ecommerce ad**
- Comment keyword: PRICE
- Public reply: Sent you the details 💌
- DM: Hi {first_name}! The Linen Weekender is $89, in four colors. / yourbrand.com/weekender /  / Use FIRST10 for 10% off your first order. Reply SIZE if you want help picking one.
- Follow up: Still thinking about the Weekender? FIRST10 is still good on your first order.

Under ads, people rarely type the keyword you would choose. Set triggers for the words they use, and let AI-generated triggers suggest more for the post. A [Global Trigger](https://replyrep.io/features/global-keyword-triggers) on "price" answers it on every ad and post at once.

## When should you automate ad comments?

- **Ecommerce and Shopify stores.** Price and link to every "how much?" on a product ad. See [Shopify stores](https://replyrep.io/for/shopify-stores).
- **Course creators.** Comment "INFO" under a course ad to get the syllabus and enrollment link. See [course creators](https://replyrep.io/for/course-creators).
- **Local services.** A gym ad offering a free first class answers "FREE" with the booking link.
- **Launches with paid support.** A [product launch](https://replyrep.io/use-cases/product-launch) where the ad and the organic reel share one keyword, so both feed the same list.

**Stop paying for unanswered comments** Set it up on your next ad and see what the comments were worth.

## How do you set up ad comment automation in ReplyRep?

1. **Connect the Instagram account the ad runs from.** Sign in through Meta with a Business or Creator account. ReplyRep never asks for your password.
2. **Choose the sponsored post.** Sponsored ad comments are their own trigger in ReplyRep.
3. **Set the keywords people actually use.** Price, how much, link, size, shipping. Add as many as you need on one post.
4. **Write the DM.** Price, link and code in the first lines, then one question they can answer.
5. **Turn on extras.** On paid plans: a public reply, an Email Collector step to capture the lead, or a Follow Up for people who go quiet.

Most ads are covered in about four minutes. For measuring what it earns, read [measure Instagram DM conversions](https://replyrep.io/guides/measure-instagram-dm-conversions).

## Which keywords work under Instagram ads?

*Common ad comments and what to send*

| They comment | Send |
| --- | --- |
| price, how much, cost | The price, the product link and a first-order code |
| link, shop, where | The product page, with the code repeated |
| size, fit | The size guide link, plus an invitation to reply with their usual size |
| shipping, delivery | Delivery times for their region and the shipping policy link |
| info, details | A two-line summary and the link to the full page |

Set each as a keyword on the ad, or as a Global Trigger if the same question comes up across all your ads. The answer in each DM should be complete on its own, because people who comment on ads often never visit your profile.

## Which plan includes ad comment automation?

The pricing table does not list sponsored ad comments as a separate row, so check [pricing](https://replyrep.io/pricing) for the current details or ask support@replyrep.io. The extras that make ad comments convert are listed: Comment Auto Reply, Email Collector and Follow Up are on Lite and up, from $10 a month.

|  | Free | Lite | Boost | MAX |
| --- | --- | --- | --- | --- |
| Price | $0 | $10/mo | $25/mo | $100/mo |
| Automated DMs a month | 2,000 | 10,000 | 40,000 | 400,000 |
| Comment Auto Reply | Not included | Included | Included | Included |
| Email Collector | Not included | Included | Included | Included |
| Follow Up | Not included | Included | Included | Included |

## What should you know before automating ad comments?

- **Ad comments come from strangers.** Your DM may be the first message they ever get from you, so lead with the answer, not a greeting.
- **Size your plan to your ad spend.** Each answered comment is one DM. A well-funded ad can bring more comments than an organic post.
- **Meta paces sending.** If an ad spikes, paid plans queue the overflow with the [Excess DM Queue](https://replyrep.io/features/viral-post-dm-queue) instead of dropping it.
- **Only people who commented get a DM.** Ad comment automation answers questions; it does not message people who only saw the ad.

## Frequently asked questions

### Can you automate replies to Instagram ad comments?

Yes. ReplyRep answers comments on sponsored posts with a DM, through Meta's official Instagram API. The usual setup sends the price, the product link and a code to anyone who comments a buying keyword like price or link.

### Does ad comment automation help ad performance?

It helps the part after the click that ads managers can't see: the people who commented instead of clicking. Answering them in seconds, with a link, gives those comments a path to purchase that they otherwise would not have.

### Should I also reply publicly under ad comments?

A short public reply, worded differently each time, shows everyone else viewing the ad that questions get answered. In ReplyRep that is Comment Auto Reply, on paid plans. Keep the price and link in the DM.

### What keywords should I use on an ad?

Use the words people really type under ads: price, how much, cost, link, size, shipping. AI-generated triggers can suggest more for the post, and a Global Trigger on price answers it on every post and ad at once.
