The Basics
What is comment selling?
Comment selling turns the comment section of a social broadcast into the checkout. During a live shopping stream, every product carries a short code on screen. A viewer who wants it doesn't hunt for a link - they type a keyword and the code, right where they're already watching and chatting.
That matters because buy-intent comments are the most perishable traffic there is. "How do I order?" written under a live video converts if it's answered in seconds - and evaporates if it isn't. Comment selling automates that answer: a public reply confirms the order on the stream (which nudges everyone else watching), and a private message delivers the checkout link straight to the buyer.
Why It Works
The shortest path from
"I want it" to "ordered"
Up to 10×
higher conversion than conventional e-commerce: companies report live commerce conversion rates approaching 30%, according to McKinsey.
2
messages per order, sent automatically: a public reply everyone watching sees, and a private one with the product link.
0
manual replies typed during your live - you present, the automation sells.
How It Works
From comment to checkout
in three steps
02
Every product gets a code on screen
Stremify renders your catalog into a branded live stream where each product carries its shop code, price, and discount - so viewers always know what to type.
03
Comments turn into orders
A viewer types "SHOP 42". Stremify replies publicly, sends the checkout link privately, tags it with UTM parameters, and the order appears in your dashboard in real time.
Manual vs automated
What changes when
the comments sell for you
Plenty of sellers run comment selling by hand: someone watches the comments, writes down who claimed what, and messages each buyer a link after the show. It works until the stream gets busy.
| Step | By hand | With Stremify |
|---|---|---|
| Spotting a buy comment | A helper reads every comment as it scrolls past | Any comment with your keyword and a product code, like SHOP 42, is picked up |
| Confirming the order | Typed reply, often minutes later | A public reply from your template, e.g. "Hey @anna, we've got your order for the linen dress" |
| Sending the link | Copy-pasted DMs after the live ends | A product card with the link, sent as a private reply by DM or Messenger |
| Double claims | Checked against a spreadsheet | The same comment never creates two orders, and a viewer can't claim the same product twice in one stream |
| Knowing what sold | Reconciled after the show | Orders appear on your dashboard during the stream; every link is UTM-tagged and click-tracked |
Setup checklist
How to set up comment selling
-
1
Connect the account you sell from
An Instagram professional account (Business or Creator) or a Facebook Page. Comment selling needs the account connected to Stremify, not just a stream key, because replies and private messages go out through it.
-
2
Import your products
Connect Shopify, WooCommerce or Magento, or a product feed URL. Each product gets a short shop code that appears on screen next to it.
-
3
Choose a keyword
SHOP is the default; you can set your own per store and override it per campaign. Pick a short word viewers can type in one go and that doesn't turn up in normal chat.
-
4
Write the public reply
Use {username} and {product} placeholders, for example "Hey @{username}, we've got your order for {product}. Check your messages." Keep it short: everyone watching reads it.
-
5
Test before you go live
Start a short test stream and comment your keyword and a code from a second account. You should see the public reply, the private message, and the order on your dashboard.
-
6
Tell viewers how to buy
Put the instruction on screen and say it out loud every few minutes: "Comment SHOP and the number to order."
Best practices
Getting more orders from the comments
- Keep codes short and visible. Numbers are faster to type than product names, and viewers only use a code they can read on a phone screen.
- Use the same keyword every show. Regular viewers learn it, and the first comment in a new stream shows everyone else how to order.
- Let the public replies work for you. Each reply shows other viewers that people are buying, so a friendly, specific reply beats a generic "thanks".
- Give each product a deadline. A countdown or a limited-time discount on screen gives viewers a reason to comment now rather than later.
- Keep checkout in your store. The link goes to the product page in your own shop, so payment, stock and customer data stay in the system you already use.

Tracked end-to-end
Every link is UTM-tagged, so each order traces back to the exact stream, product, and comment that made it.

Comment-to-buy orders land in your dashboard the moment they happen - watch the live convert while it runs.
Comment selling FAQs
What is comment selling?
Comment selling is selling products directly through the comments of a social media broadcast. Instead of pushing viewers to a bio link or an external shop, they type a keyword and a product code - like "SHOP 42" - under your live stream, and the sale is handled from there: an automatic reply confirms the order and a private message delivers the checkout link.
How does comment selling work with Stremify?
Every product in your live stream carries a shop code on screen. When a viewer comments your keyword plus the code (for example "SHOP 42"), Stremify replies publicly under their comment and sends them a product card with a checkout link privately - by DM on Instagram, by Messenger on Facebook. No typing on your side, no missed comments.
Which platforms support comment selling?
Stremify runs comment-to-buy on Instagram Live and Facebook Live. You can also stream a campaign to YouTube or Twitch, but the automatic comment replies and private checkout links work on your Instagram and Facebook broadcasts.
Do my buyers need an app or an account?
No. Buyers just comment - the reply and the private checkout link arrive inside the platform they are already using, and the link opens the product page on your own store. There is nothing to install and no marketplace account to create.
Can I customize the keyword and the replies?
Yes. You choose the trigger word (SHOP, BUY, or anything else) and can customize the public reply and the call-to-action per campaign, so the automation still sounds like your brand.
How much does comment selling with Stremify cost?
Comment-to-buy is built into Stremify. The platform is credit-based: you buy streaming credits and pay only for the minutes you stream. There is no subscription, and every new account gets free credits to try it out - no credit card required.
What happens if a viewer comments the same code twice?
Nothing extra: a comment never creates more than one order, and the same viewer can't order the same product twice in one stream, so re-posted or duplicated comments don't turn into duplicate orders.
Where does the buyer pay?
In your own store. The private message links to the product page in your shop, tagged with UTM parameters, so payment, stock and customer data stay in the system you already use.
Is comment selling the same as comment-to-buy?
Yes, they are two names for the same thing: viewers order by commenting during a live stream instead of following a link. Stremify calls the feature comment-to-buy.
