Messenger, WhatsApp or website: which channel should your chatbot start on?

You've decided to put a chatbot to work for your business. The very first question is where. On your website? On Messenger, where your customers already write to you? Or on WhatsApp, because everyone has it? Picking the wrong order won't sink you, but it can cost you weeks: you set up a channel that barely gets any questions, while you keep answering the important one by hand at ten in the evening.

In this article we go through the channels one by one: what each is good for, where its limits are, how much work it takes to set up, and in what order it makes sense to launch. At the end you'll get a simple decision rule you can run on your own business in ten minutes.

First, check where your customers ask questions today

Before you set anything up, take a quick inventory. Go through the enquiries of the last two weeks and count where they came from:

• how many came in on Messenger,
• how many as Instagram DMs,
• how many on WhatsApp or by text message,
• how many by email or through your website contact form,
• and how many people phoned with a question a good description would have answered.

This inventory is worth more than any general advice. For a beauty salon, Messenger and Instagram usually win; for a webshop, it's the website and email; for a B2B service provider it's often the contact form. Put the chatbot first where most of the repetitive questions arrive today, because that's where it pays off fastest.

Website widget: the easiest place to start

The website chat window takes the least admin. You paste one line of JavaScript into your site, and it works on WordPress, Wix, Squarespace, Shopify or a custom-built site. You don't need a Meta account, business verification or a separate phone number.

What it's good for: it answers people who are already on your website, which means they're interested. They ask about prices, delivery and free slots. If the chatbot answers right away, they don't leave the page planning to write "later".

Its limit: only people who reach your site will see it. If your customers mostly discover you on Facebook or Instagram, website chat alone won't catch them.

A bonus you only get here: proactive greetings. You can have the chatbot say hello on its own, for example when someone has been looking at your pricing page for more than 30 seconds. ChatAutomata's live visitor view also shows you who is on your site right now and which page they're on.

ChatAutomata's free plan does exactly this: one chatbot on your website, 100 messages a month, with no time limit. It's the cheapest way to try it. If the first week shows that visitors ask different things than you expected, you can fix that calmly while traffic is still low, before the chatbot starts talking on your busier social channels.

Messenger and Instagram DM: where your customers already write

If Facebook and Instagram messages lead your inventory, don't start with the website. Messenger and Instagram DM catch questions where people already write to you, often after a post or an ad, in the evening or at the weekend.

What you need to prepare:

• For Messenger, a Facebook Page you're an admin of.
• For Instagram, a professional (business or creator) account linked to your Facebook Page. It doesn't work with a personal account.

The key limit: the 24-hour window. Under Meta's rules, a business can reply freely within 24 hours of someone messaging it. After that the conditions are much stricter. That's no problem for a chatbot, since it replies instantly, but you can't use it to send promotional messages, such as a sale, to everyone who ever wrote to you. Here the chatbot is customer service, not a newsletter.

What to watch: Messenger and Instagram messages are short and direct. "How much is it?", "Any free slot on Saturday?", "Where are you?" dominate. Your knowledge base should have short, precise answers to these, not a three-page description. We wrote about this in detail using a beauty salon as an example: taking bookings on Messenger after hours.

WhatsApp: a strong channel that needs more preparation

For many customers WhatsApp is the most natural channel, especially if you already arrange things with them there. For a business chatbot, though, you don't use the regular WhatsApp app but the WhatsApp Business Platform (Meta's business API).

What that means in practice:

• The phone number has to be registered with the business platform. It's worth using a separate number, because a number connected to the platform can't be handled the same way as the app on your own phone.
• Meta may ask for business verification (company details, documents), which can take a few days.
• There's a 24-hour customer service window here too. To message someone outside it, you need a pre-approved message template, which Meta charges for separately.

When it's still worth it: if your customers specifically prefer WhatsApp, for example foreign guests at a holiday rental, or services where people send photos and documents. ChatAutomata answers here from the same knowledge base as on your website, so you don't have to write everything twice.

If you're just starting out, WhatsApp is rarely the right first choice. Let the chatbot run for a week or two on a simpler channel, fill the gaps in your knowledge base, and only then connect it here too.

Telegram and internal channels

Technically, Telegram is the fastest channel to connect: creating a bot takes minutes and there's no business verification. Among Hungarian small businesses, however, only a small share of customers use it, so it works best as an extra channel, or for communities that already have a Telegram group.

Internal channels are worth a mention too. ChatAutomata can send notifications to Slack, Microsoft Teams and Discord, for example when a new lead comes in or a visitor asks for a human. These aren't customer channels; they're for your team. You don't need to watch the chat dashboard all day, because the important events show up where you already work.

The recommended launch order

If there's no clear winner in your inventory, this order works for most small businesses:

1. Week 1: website widget. The risk is lowest here. Fill your knowledge base, watch the conversations and improve the answers. We explain how in our article on training a chatbot on your own content.
2. Week 2: Messenger and Instagram. Same knowledge base, new channel. This is where the short, quick questions arrive, so check that your answers are concise enough.
3. Weeks 3–4: WhatsApp, if your customers are there. By then your knowledge base has matured, and the wait for business verification doesn't hold anything up.
4. Any time: internal notifications to Slack, Teams or Discord if you work as a team.

For the details of the first month (what to watch, when to step in, when to let it run), here's a week-by-week guide: launching a chatbot: the first 30 days.

How much work is each channel? A quick comparison

• Website widget: 10–15 minutes to set up, no Meta admin. Good for: interested visitors on your site, proactive greetings.
• Messenger: about half an hour if you already have a Facebook Page. Good for: quick questions after posts and ads.
• Instagram DM: similar, but you need a professional account linked to a Facebook Page. Good for: visual trades (beauty, photography, crafts).
• WhatsApp: the most preparation (number, verification, templates). Good for: longer conversations, foreign guests.
• Telegram: ready in minutes, but few Hungarian customers use it.

A note on plans: ChatAutomata's free plan covers website chat. The Pro plan includes all eight channels (web, Messenger, WhatsApp, Instagram, Telegram, Slack, Teams, Discord) and is free until 31 December 2026. That means you can try every channel until the end of the year and decide which ones to keep based on your own data.

Two typical situations

A beautician who gets most clients from Instagram. The inventory shows that two thirds of the questions come in as Instagram DMs, mostly between eight and ten in the evening, and half of them are the same: how much a treatment costs and when there's a free slot. The website widget can go live on day one, since it takes five minutes, but the real gain comes from connecting Instagram in week two. If the chatbot answers from the price list and can see free slots in the calendar, most evening messages are confirmed bookings by morning instead of unanswered questions.

A small webshop where questions come after the order. Here the inventory points to the website and email: "Where's my parcel?", "When will it arrive?", "Can I exchange it?". The website widget is the first step, and with a webshop connection (for example WooCommerce, Shoprenter or Unas) the chatbot can check the order status too. Messenger is only a second step here, because most buyers go back to the website after ordering, not to the Facebook Page.

The lesson is the same in both cases: the right channel isn't the one that's popular in general, but the one where your customers ask.

One knowledge base, many channels: don't forget this

The most common mistake is writing separate answers for every channel. Three months later the website shows the new price and Messenger still shows the old one. In ChatAutomata, one chatbot works from the same knowledge base across all its channels, so when you change an answer once, it updates everywhere.

The same goes for live handover. If the chatbot can't answer, or the visitor wants to talk to a person, a team member can take over the conversation on any channel and then hand it back to the chatbot. Lead details all land in one place, whatever the channel. How a conversation turns into a customer is covered in our article on lead generation with a chatbot.

If you're a service provider taking appointments, have a look at the booking chatbot page; if you run a webshop, see the webshop chatbot. Both work on any channel: booking a slot or checking an order status works the same on your website as on Messenger.

Decide in ten minutes

Here's the whole thing as one simple rule:

• If most questions arrive on your website, or you don't know where to start: website widget.
• If your customers write on Facebook or Instagram: Messenger and Instagram, alongside the website.
• If you already arrange things with existing customers on WhatsApp: WhatsApp, but as a second step.
• If you work as a team: switch on notifications to your internal channel.

The Pro plan is free until 31 December 2026, so you can try every channel with no risk. Sign up for free, start with your website, and in two weeks your own conversations will show you where to go next.
