Most digital advertising assumes a familiar path: someone sees an ad, clicks through to a website, and buys or fills in a form. For many businesses and many customers, that path is not the natural one.
In much of Latin America, South Asia, Southeast Asia, Africa and the Middle East, messaging apps such as WhatsApp are part of everyday life, including for dealing with businesses. People ask about prices, check availability, arrange delivery and pay through chat. For them, a conversation feels more natural, and more trustworthy, than an unfamiliar checkout page.
Click-to-message ads are built for that behaviour. Instead of sending people to a website, they open a conversation with the business directly.
How they work
On Meta's platforms, advertisers can run ads that open a chat in WhatsApp, Messenger or Instagram Direct when someone taps them. The conversation often starts with a pre-filled message or a set of suggested questions, so the customer does not have to think about what to type.
From there, the business responds, answers questions, recommends products and, where it makes sense, completes the sale within the chat. Businesses with higher volumes typically use the WhatsApp Business Platform or similar tools to manage conversations across a team, often with automated replies for common questions.
Where they work best
Click-to-message ads are not the right choice for every product, but they are particularly strong in a few situations.
| Considered purchases. | When customers want advice before buying, such as for electronics, education, travel or financial products, a conversation answers questions a product page cannot. |
|---|---|
| Local and service businesses. | Booking appointments, checking availability or requesting a quote often works better in chat than through a form. |
| Markets where chat is the norm. | Where messaging is how people already talk to businesses, a chat-based path can feel far more familiar than a website. |
| Businesses without a strong website. | For smaller advertisers, a well-run chat can replace some of what a full e-commerce site would otherwise have to do. |
The conversation is the product
The ad is only the start. What happens in the chat decides whether the campaign succeeds.
Reply quickly.
People who start a conversation expect a response while they are still interested. Slow replies waste the ad spend that brought them in.
Plan the first messages.
Suggested questions and a clear, friendly greeting guide people towards what they need and make it easier to qualify them.
Mix automation and people.
Automated replies work well for common questions and out-of-hours messages. Complex questions and closing a sale usually need a person.
Respect the channel.
Messaging is personal. Follow up only with consent, keep messages relevant, and follow the platform's rules on what businesses may send.
Measuring what matters
Measuring click-to-message campaigns on clicks or conversations started tells only part of the story. The real measure is what those conversations produce: qualified enquiries, bookings and sales.
That requires tracking outcomes inside the conversation, for example by tagging chats that lead to a sale, and, where possible, sending those outcomes back to the ad platform so it can optimise towards people who buy rather than people who simply start chatting.
Meeting customers in their own channel
Click-to-message ads work because they fit how many customers already prefer to deal with businesses. For advertisers in markets where chat is the norm, or selling products that benefit from a conversation, they can turn an ad into a relationship rather than a single click. The advertisers who do best treat the chat not as a side channel but as the place where the sale actually happens.
