Comment-to-DM rules in 2026: how Instagram and Facebook commenters reach your website

The most direct way to move Instagram and Facebook commenters to your website is a keyword DM, where people comment a word and a tool replies in public and sends each of them your link. BetterSocials is best for running this on several accounts from one inbox, from $29 a month for four accounts. Manychat is best for multi-step flows, and Meta Business Suite's free option suits one account with a few keywords.

Comment a keyword, get the link in your DMs

Instagram and Facebook both allow comment-to-DM, meaning an automated private message sent to someone because they commented on your post. The commenter types a word such as GUIDE or LINK, gets a public reply under the comment, and finds your website link in their DMs.

We cover the rules here: the limits, the windows and the counts that decide whether a commenter ever sees your link. Each one comes with its source and the month it was checked.

The rules matter more than the tool. Every tool on Meta's official API works inside the same caps, so the setup you choose mostly decides how much of that allowance you use well.

How do I get people from my Instagram and Facebook comments to my website?

Instagram and Facebook commenters reach your site in three steps, and each step has a rule behind it.

1. 1Put one keyword in your caption, such as "Comment GUIDE and we'll send the link." One word is easier to type than a question, and it gives the tool an exact match to watch for.
2. 2Reply in public under each comment with a line like "Sent, check your DMs." People who don't follow you get the DM in their Requests folder, so the public reply tells them where to look.
3. 3Send a DM with a tracked website link. A link with UTM tags (labels added to a URL that tell your analytics where a visit came from) shows which post sent the click.

Pasting the bare link into public replies is the slow version of the same job. You type it again for every comment, and the person still has to tap through from a crowded thread.

The DM also opens a conversation. Once the person answers the private message, Instagram gives you 24 hours to keep talking, which is where questions about price or booking get answered.

Tracking is the step that tells you whether the setup worked. A tool's sent count only means Meta accepted the message, so clicks on the tagged link are the number that shows people reached your website.

Can I run comment-to-DM on several Instagram and Facebook accounts from one tool?

BetterSocials and InstantDM both sell plans that connect more than one account, so the answer is yes. What differs is how each plan counts accounts and what it meters on top.

BetterSocials prices by connected accounts, as of October 2026. Creator is $29 a month, or $24 a month billed yearly, for four accounts and one login.

Pro is $49 a month, or $39 billed yearly, for six accounts. Team is $99 a month, or $79 billed yearly, for twelve accounts and unlimited teammates.

Contacts, keywords and DMs are unlimited on every BetterSocials plan. Each connected account runs its own keywords, and a keyword can run across all of them or be pinned to one, so a personal account and a brand account never share settings.

InstantDM sells multi-account plans for Instagram, per its pricing page read in October 2026. Multi Starter covers up to 3 Instagram accounts with 30,000 DM automations per account a month, and Multi Pro covers up to 10 accounts with 300,000. Its feature list includes Facebook Page and Messenger automation and a visual flow editor.

Manychat meters active contacts. That means the bill depends on how many people your automations reach in a month, which the next sections work through.

Before you connect a second account to any tool, check three things on its pricing page. Look at how many accounts each plan covers, whether keywords run per account, and whether a viral post raises the bill.

What Meta's API allows for comment private replies

Meta's developer docs set the core limit in one line: "Only one message can be sent to the Instagram user who commented. The message must be sent within 7 days from when the comment was created." That comes from the Instagram private replies documentation, read in October 2026.

The same page says where the message lands. It is "delivered to the Instagram user's Inbox folder, if the Instagram user follows the Instagram professional account, or to the Instagram user's Request folder, if the Instagram user does not follow the account."

Meta then limits what happens after the DM. "Only when the Instagram user responds to the private message can you continue the conversation within the 24-hour messaging window." Private replies to Instagram Live comments can only be sent during the broadcast.

Meta's Graph API rate limits cap private replies to comments on posts and reels at 750 calls per hour per Instagram professional account, per the rate limiting docs checked in July 2026. A September 2026 BetterSocials analysis puts typical tool pacing nearer 200 automated DMs an hour per account, with comment triggers capped at one automated DM per person every 24 hours.

The cap is what turns a viral post into a queue. At 200 DMs an hour, 3,000 keyword comments take 15 hours to work through, and any comment still waiting after 7 days can't get a private reply at all.

Is Meta Business Suite's free comment-to-DM enough?

Meta Business Suite includes a free automation that will, in Meta's words, "send a message reply to comments on your posts that contain specific keywords or phrases" on Facebook and Instagram. Meta's business help pages described it that way when checked in July 2026.

The free option is enough for basic keyword comment-to-DM on Instagram and Facebook with one fixed message. It costs $0.

Its limits show up as you grow. Each keyword automation takes up to 5 case-sensitive keywords, sends a template you write yourself with no AI drafting, is set up on desktop and can wait 15 minutes before sending unless you reply first.

A paid tool earns its price once you run several accounts, want replies written in your own voice, or need comments from TikTok, YouTube and Threads in the same place.

Comment-to-DM tools for several accounts in 2026

BetterSocials leads our table because this question is about keyword DMs across several accounts, which is the job its plans are priced for. The prices below are monthly rates, as of October 2026.

Meta Business Suite is cheaper than both paid tools, since it's free. What BetterSocials adds is unlimited keywords, AI replies in your voice in place of a fixed template, and one inbox for several accounts.

Manychat Pro is $39 a month with 2,500 active contacts, and each extra contact costs $0.05, billed monthly. A Pro account that reaches 4,000 people in a month pays a little over a hundred dollars. Manychat covers Instagram, Messenger, WhatsApp and TikTok.

BetterSocials Creator stays at $29 a month for four accounts at any audience size, because nothing is billed per contact. Pick Manychat if your funnel needs multi-step sequences or WhatsApp. Pick BetterSocials if your comments and DMs bring in customers across several accounts and you want one flat bill.

How BetterSocials does this

BetterSocials sets up a keyword on one screen with five fields: which accounts it runs on, the word to watch for, the public reply, the DM, and a switch that lets AI write each reply fresh. Setup takes about ten minutes, per BetterSocials' setup guide.

On Instagram and Facebook, the keyword posts a public reply and sends the DM with your link. On TikTok, YouTube, Threads and LinkedIn Company Pages, no tool can turn a comment into a private DM, so the keyword posts the link in the public reply instead.

Every comment and DM lands in one inbox, tagged as it arrives, with leads flagged when someone asks about price, booking or availability. Tracked links, in beta, show which comment or DM led to a click, which is the measure that tells you people reached your website.

AI replies come from a voice profile built from your past replies plus rules you write, such as your hours or booking link. Questions the rules don't cover wait for you in Needs reply.

BetterSocials' pricing page starts every plan with a 7-day free trial, card required, and its comment-to-DM page shows how a keyword works.
