Click to WhatsApp Ads: How to Turn Facebook and Instagram Ads Into Real Conversations

Lipi prints wedding cards in Old Dhaka. Last winter she ran her first ad with a “Send WhatsApp message” button and Tk 500 a day. By the second evening her phone showed 140 unread chats. Most said one word: “price?”. She answered until 1 am, quoted the same rates sixty times, and booked four orders.

The ad had worked. Everything after the ad had not. That is the usual story with click to WhatsApp ads: getting conversations is the easy half. This guide covers both halves, with more time on the second.

How click to WhatsApp ads work

They are ordinary Facebook and Instagram ads with one difference: the button opens a WhatsApp chat with your business instead of a website. The person sees a pre-filled first message, taps send, and the conversation is in your WhatsApp inbox with a small label showing which ad it came from. Marketers often shorten the name to CTWA ads.

You build them in Meta Ads Manager. You pay Meta for showing the ad, exactly as with any other campaign. There is no extra charge from WhatsApp for receiving the message in the WhatsApp Business app.

Look at where people fall away. A large share tap the ad and never send the message. More leave when the reply takes an hour. The ad platform reports the top of this funnel. Your profit is at the bottom.

Is WhatsApp the right destination for you?

Buyers in Bangladesh often want to talk to a person before paying, especially for anything customised, expensive or bought on cash on delivery. That makes chat a natural fit. It is a poor fit when you sell a low-priced item in volume and nobody is free to answer. Three hundred chats a day with one person replying is not a sales channel. It is a queue.

A fair test: if you already close most sales in the inbox, WhatsApp ads will suit you. If your website already takes orders without conversation, keep sending traffic there and use WhatsApp for retargeting and support.

Before you launch

• The WhatsApp Business app on a number that stays with the business, not an employee’s personal SIM.
• A complete business profile: name, category, description, hours, address, website.
• The number linked to your Facebook Page. In Page settings, find Linked accounts, choose WhatsApp and confirm with the code sent to the phone.
• A catalogue with your main products, photos and prices, so you can send an item card instead of typing.
• Someone assigned to reply for the hours the ad runs.

If several people must answer from one number, the app allows a limited number of linked devices. Beyond that you need the platform version, explained in WhatsApp Business API in Bangladesh.

Setting up the campaign

1. Choose the objective. In Ads Manager, create a campaign with the Engagement objective for conversations, or Sales or Leads if you can report results back to Meta.
2. Set the conversion location to Messaging apps and tick WhatsApp. You can tick Messenger and Instagram too if you answer there.
3. Pick the performance goal. “Maximise number of conversations” is the starting point for most accounts.
4. Set audience and budget. Limit the location to where you deliver. Our Facebook ads targeting guide covers the choices.
5. Schedule the ad for hours when someone can reply, if your budget type allows scheduling. Otherwise set an away message for the night.
6. Build the ad. Add the video or image, the text, and the “Send WhatsApp message” button.
7. Edit the message template. Write the pre-filled message the customer will send, or add tappable questions such as “What is the price?” and “Do you deliver to my area?”.

That last step is skipped by most advertisers and matters more than it looks. A pre-filled message of “Hello! Can I get more info on this?” tells you nothing. “I want the price list for 100 wedding cards” tells you what to send back.

Writing the ad so the right people message

A messaging ad that hides the price gets the most chats and the fewest sales. The purpose of the ad is to filter, so the people who write in are already partly sold.

• State a price or starting price. “Wedding cards from Tk 35 each, minimum 100 pieces.”
• State where you deliver and the delivery charge.
• Show the product in use, ideally on video, with size and material visible.
• Tell them what to send. “Message us your event date and quantity for a quote.”
• Say when you reply. “We answer 10 am to 10 pm.”

Yes, this lowers the number of chats. It lowers the number of useless ones much faster.

The first five minutes

People who message from an ad are usually messaging two or three other sellers at the same moment. The first useful reply tends to win. Prepare three things inside the WhatsApp Business app, under Business tools.

Greeting message

Sent automatically to a new contact. Use it to answer the obvious and ask one question.

Away message

Sent outside your hours. Say when you will reply, and keep the promise.

Quick replies

Saved answers you insert by typing “/” and a shortcut. Write one for each question you answer daily: price list, delivery charge and time, payment methods, return policy, how to order. Ten good quick replies cut reply time more than hiring another person.

A chat flow that closes

You do not need a clever script. You need the same four moves every time.

1. Answer what was asked. If they asked the price, give the price in the first line.
2. Ask one qualifying question. Size, quantity, area or date. One, not five.
3. Recommend one option and send its catalogue card or photo. Too many choices stall the chat.
4. Ask for the order plainly. “Shall I book this for you? I need your name, full address and phone number.”

Confirm the order in one message that repeats the item, total, delivery charge, address and date. It prevents disputes and cuts refused parcels. For more on that problem, see how to reduce fake COD orders.

Following up

Many buyers go quiet after the quote. Use labels in the app, such as “New”, “Quoted”, “Ordered” and “Follow up”, and send one polite message the next day to everyone labelled “Quoted”. One follow-up is service. Five is spam, and people who block or report you hurt the quality rating of your number.

Measuring what matters

Ads Manager shows “messaging conversations started” and the cost of each. It cannot see which chats became orders unless you tell it. In the example above, the ad with the cheap chats is the expensive one.

The simple method

WhatsApp shows which ad a chat came from at the top of the conversation. Keep a sheet with a row per order and a column for the ad name. Once a week, divide each ad’s spend by its confirmed orders. Ten minutes of work, and you will make better decisions than most advertisers who look only at Ads Manager.

The advanced method

With the WhatsApp Business Platform and a CRM or partner tool, you can send “Lead qualified” or “Purchase” events back to Meta through the Conversions API. The campaign can then optimise for buyers instead of for people who merely chat. If your reports and reality disagree, begin with how to fix ad tracking.

Mistakes that drain the budget

• No price in the ad. You pay to be asked the same question hundreds of times.
• Running ads while nobody is replying.
• Choosing the cheapest-chat ad without checking orders.
• Typing every answer by hand when quick replies exist.
• Using a personal number. When that staff member leaves, the customer list leaves too.
• Sending promotions to everyone who ever messaged. Blocks and reports can get a number restricted.
• Scaling the budget before the inbox can cope. Double the budget only when replies are still fast at the current level.

What Lipi changed

She did three things in one afternoon. She added “from Tk 35 per card, minimum 100 pieces” to the ad text. She set a greeting that asked for the event date and quantity. And she wrote eight quick replies and showed her younger brother how to use them between 6 pm and 10 pm.

The following week she received fewer than half as many chats and booked more orders than before, and she was asleep by eleven. Nothing about the targeting or the budget had changed.
