Click-to-WhatsApp ads: turning ad clicks into conversations

Click-to-WhatsApp ads are Meta ads on Facebook and Instagram that open a WhatsApp chat with your business instead of a website or form. They suit businesses that sell through conversation, which is most of India. You can use the WhatsApp Business app for small volumes or the WhatsApp Business Platform (API) for automation, CRM integration and better tracking. Judge them on qualified conversations and sales, not message count.

200 “Hi”s and no replies

A Kannur interior designer got 200 WhatsApp chats in a week from a ₹7,000 campaign. Most said only “Hi” or asked the price, then went silent.

Nobody replied for hours, and there was no greeting or quick question to qualify them.

They added a pre-filled message, an instant greeting with three quick-reply options (budget, room, city) and a 10-minute reply rule. Chats fell to 140, but site visits doubled.

Illustrative example based on a common pattern in Kerala e-commerce accounts. Numbers rounded.

What click-to-WhatsApp ads are

In Ads Manager, choose a messaging destination with WhatsApp under the Engagement, Leads or Sales objective, and connect your WhatsApp number to the Page.

With the WhatsApp Business Platform you can connect a CRM, tag leads by ad, and send purchase or lead events back to Meta. Meta has made replies within 72 hours of an ad click free (free entry point); check current WhatsApp pricing for template messages.

Cost per qualified chat = ad spend × 1.18 ÷ chats that answered your qualifying questions

When the number lies

Conversations started ≠ leads
Many chats are a single “Hi”. Count chats that answer your questions.
Sales happen offline
Without CRM tracking, Meta can’t see which chats bought.

Mistakes to avoid

  • No greeting or quick replies

    People drop off after “Hi”.

  • Slow replies

    Leads go to competitors who reply first.

  • Judging on cost per conversation

    Cheap chats, no sales.
