Auto-reply to TikTok comments with a link: 5 steps for 2026
A TikTok keyword auto-reply posts your link in a public reply under the comment. Five steps take that commenter to a DM, a Lead tag and a customer.

Yes, you can auto-reply to TikTok comments with a keyword, and the link goes out in a public reply under the comment. Outside TikTok's limited rollout in Vietnam, Thailand and Indonesia, no tool can turn a TikTok comment into a private DM. The private conversation starts when the person writes to you.
For creators, local businesses and small agencies, BetterSocials is our pick. It posts the keyword reply, puts TikTok comments and DMs in one inbox and tags the people asking about price or booking as leads, from $29 a month for four accounts.
Every price here is what the vendor's own page listed in October 2026. Manychat suits teams that want WhatsApp and Messenger in the same tool. Pallyy suits teams that only need TikTok comments in an inbox, which starts on its Pro plan at $25 a month, or $20 billed yearly.
Where the link lands when someone comments your keyword
TikTok decides where your link can go. A keyword reply can only post it in public.
The rule watches your comments for one word and answers every comment that contains it. On TikTok, that answer is a public reply under the comment, with your link in it.
Instagram and Facebook work differently: there, a keyword comment can send the person a private DM with the link, which is what comment-to-DM means. On TikTok, the private conversation opens only when the person messages you. Then a business gets ten replies within 48 hours.
The steps below assume you run a TikTok Business account and have one link worth sending. We also assume your site runs an analytics tool such as GA4 that reads UTM tags, the labels added to the end of a link that name where a visit came from.
Setting up a keyword reply in BetterSocials
BetterSocials builds a keyword reply on one screen, under Comment to DM, then New keyword link. Its setup guide lists five fields and puts the first keyword at two or three minutes of work.
There's no flow builder to draw.
- Accounts: the connected accounts the keyword runs on, all of them or just one.
- When someone comments: the word itself, such as GUIDE or LINK. Capitals don't matter.
- Reply on the comment: what your account posts in public under their comment.
- And DM them this: the message and the link. A TikTok comment has no DM to send, so on TikTok this message posts as the public reply with the link.
- AI replies: off to start. Switched on, each reply is written fresh in your tone instead of one canned line.
After Go live, the keyword answers matching comments on your recent and active videos, while comments on old videos surface in the BetterSocials Inbox for you to answer by hand. Keywords are unlimited on every plan. Nothing is billed per contact.
The same keyword can run on Instagram and Facebook too. There it sends a real DM with the link and posts a public reply under the comment.
Five steps that turn a TikTok comment into a lead
A TikTok comment becomes a lead when each step hands the person to the next one. We'd run these five in order.
- Use a TikTok Business account and connect it. TikTok's DM replies need a Business account. In BetterSocials, you connect from Connected Accounts and sign in on TikTok's own screen, so your password never touches the tool.
- Ask for one word in the video and the caption. Say the keyword out loud and repeat it in the caption, so commenters know exactly what to type. One word per offer keeps each reply matched to the right link.
- Write the public reply with the link. On TikTok the reply is the whole delivery, so the link goes in it. Tell the person they can message you with questions, because their message is what opens the DM.
- Answer the DMs inside 48 hours. Once someone messages you, TikTok allows ten replies within 48 hours of their last message. BetterSocials can draft or send those replies in your voice for accounts outside the UK and Europe.
- Work the Lead tag first. BetterSocials tags every comment or DM that asks about price, booking or availability as a Lead when it arrives. Answer those before the compliments, since they're the people asking to buy.
TikTok's in-app comment settings are filters
TikTok's Help Center describes its comment settings as filters that hide comments until you approve them. With Filter unwanted comments on, "recent comments that may be offensive or spam will be hidden unless you approve them." Keyword filters work the same way: comments with your chosen words "will then be hidden unless you approve them."
The 500-keyword figure you may have seen belongs to LIVE. TikTok's page on comments in TikTok LIVE puts the limit this way: "Add up to 500 keywords or phrases that you want to block and hide from your LIVE chat." Each keyword can run up to 30 characters.
Tools that answer comments work through TikTok's comment API. TikTok's documentation for managing comments on owned videos lists endpoints to create, reply to, like, hide, delete and list comments. Its webhook, a notice TikTok sends to a connected app, fires "within five minutes of a comment or reply being created."
Manychat on TikTok, and what its contacts cost
Manychat works on Instagram, Messenger, WhatsApp and TikTok. On TikTok it meets the same rule as every tool: outside the rollout in Vietnam, Thailand and Indonesia, no tool can turn a TikTok comment into a private DM.
Manychat bills by active contacts. Pro is $39 a month with 2,500 active contacts, and each extra contact costs $0.05 on Pro, billed monthly. On Essential it's $0.10, and on Business $0.025.
A Pro account that reaches more than 2,500 people in a month pays $39 plus $0.05 for every contact past that line. BetterSocials doesn't bill per contact, so in that same busy month the Creator bill stays at $29.
If you want multi-step sequences in a flow builder, or WhatsApp in the same tool, Manychat is the better fit. BetterSocials fits when the job is a keyword reply plus answered comments on TikTok, Instagram, Facebook and YouTube, and DMs on the first three, from one inbox.
The limits TikTok sets on business DMs
TikTok never lets a business, or any tool, start a DM. The person writes first.
Then the clock starts. BetterSocials's own pages put the window at ten replies within 48 hours of the person's last message.
The limits below come from BetterSocials's product documentation, read in October 2026.
| Rule | Limit |
|---|---|
| Who writes first | The person, never the business |
| Replies | Ten within 48 hours of their last message |
| Reply content | Text up to 6,000 characters, or one image |
| Account type | A TikTok Business account |
| Replies from apps | Accounts outside the UK and Europe |
BetterSocials answers TikTok DMs from the DMs section of its AI replies, which has three settings: Off, Draft for me and Reply in my voice. On Reply in my voice, a DM gets an answer about a minute after it arrives. When your AI rules don't cover what the person asked, the DM waits for you in Needs reply.
The AI reads the conversation so far, so it doesn't repeat itself or ask for something the person already said. After five AI replies in one conversation in a day, the rest wait for you.
Counting the leads TikTok comments bring in
Every new comment and DM in BetterSocials gets a tag when it arrives: Lead, Spam, Support, Comment to DM or Archived. A Lead asks about price, booking or availability. Lead detection is free and on by default.
A new lead sends a push notification to your phone. Leads you haven't answered get at most one reminder email a day.
Link tracking is where TikTok falls behind. BetterSocials adds UTM tags to keyword links on Instagram, Facebook, YouTube, LinkedIn Company Pages and Threads, and TikTok keyword links go out untagged for now.
BetterSocials never rewrites a link you typed into a template, so type the UTM tags into the TikTok link yourself. In GA4, the visits show under Reports, then Acquisition, then Traffic acquisition, in the session source / medium rows.
What we would do, and what BetterSocials costs
For creators, local businesses and small agencies whose comments and DMs bring in customers, BetterSocials is the tool we'd start with. During the 7-day free trial, we'd connect the TikTok account that gets the most comments and write one keyword. Then we'd answer the Lead tags by hand for a while. AI replies for DMs would come after that.
BetterSocials has three plans. Creator is $29 a month for four social accounts and one login. Pro is $49 a month for six accounts. Team is $99 a month for twelve accounts with unlimited teammates. Every plan includes unlimited contacts and unlimited keyword automations, and the trial needs a card. BetterSocials's pricing page lists the plans, and its step-by-step setup guide covers the first keyword.
FAQ
What does TikTok's own comment automation do?
TikTok's Help Center describes comment filters and keyword filters that hide matching comments until you approve them. LIVE chat has a block list of up to 500 keywords. To answer a keyword comment with your link, you connect a tool that works through TikTok's comment API, such as BetterSocials.
Can a TikTok comment trigger an automatic DM?
No, not outside TikTok's limited rollout in Vietnam, Thailand and Indonesia. Everywhere else, TikTok doesn't let BetterSocials or any other tool start a DM from a comment. The keyword posts a public reply with your link instead, and once the person messages you, you can answer in their DMs.
How many times can a business reply to a TikTok DM?
Ten replies within 48 hours of the person's last message. Each reply is text up to 6,000 characters or one image, never both, and the account has to be a Business account. TikTok never lets a tool start a DM, so the person always writes first.
What does Manychat cost for TikTok automation?
Manychat Pro is $39 a month with 2,500 active contacts, and each extra contact costs $0.05, billed monthly. Manychat works on Instagram, Messenger, WhatsApp and TikTok. BetterSocials Creator is $29 a month for four accounts with unlimited contacts and unlimited keywords.
Can AI answer my TikTok DMs?
Yes. In BetterSocials, the DMs section of AI replies answers Instagram, Facebook and TikTok DMs in your voice, for TikTok accounts outside the UK and Europe. The AI reads the conversation first, and after five AI replies in one conversation in a day, the rest wait for you.
Can I track clicks on a TikTok keyword link?
No, not with BetterSocials link tracking yet, because TikTok keyword links go out untagged. Link tracking covers Instagram, Facebook, YouTube, LinkedIn Company Pages and Threads. BetterSocials never rewrites a link you typed, so add your own UTM tags to the TikTok link and read the visits in GA4.
