How to Run WhatsApp Ads: A Click-to-WhatsApp Campaign Guide
There is no ad space inside WhatsApp; the ads run on Facebook and Instagram and bring people into your WhatsApp chat. Here is the setup, the message flow, the budget and the metrics to watch, step by step.
A WhatsApp ad is a Meta ad shown on Facebook or Instagram that takes the person who taps it straight into your business's WhatsApp chat. There is no ad space inside the WhatsApp app itself; you build the ad in Meta Ads Manager and choose messaging apps › WhatsApp as the conversion location. When someone taps the button, a chat opens with a welcome message you wrote.
This guide covers the setup step by step, which businesses it suits, a message flow that turns chats into sales, budgeting and the metrics to measure.
Who are WhatsApp ads for?
- Products that need advice — customers with questions about price, size or fit decide faster in a chat.
- Appointments and bookings — beauty, education, tourism and other service businesses.
- Local businesses — where "is it in stock, can you deliver today" needs a quick answer.
- Community and channel growth — inviting people from the chat to a channel or community.
What you need first
- A WhatsApp Business account — your business number registered in the WhatsApp Business app or on the WhatsApp Business Platform.
- A connected Facebook Page — link the number to your Page under linked accounts in Page settings.
- An ad account with a payment method — active in Meta Ads Manager.
- A reply plan — who answers, during which hours, with which saved replies?
Step by step: setting up a WhatsApp ad
- Choose the objective — Engagement to grow conversations, Leads to collect contacts, Sales for purchase-focused flows.
- Set the conversion location — at ad set level choose WhatsApp under messaging apps and select your number.
- Audience and location — pick the area and language you serve; do not narrow the audience too much in the first test.
- Budget and schedule — use ad scheduling so ads run when you can answer messages.
- Ad copy and creative — put the offer and the reason to message you in the first line.
- Welcome message and quick questions — write the message shown when the chat opens and 2–4 question buttons.
- Publish and watch the first chats — check reply time and chat quality in the first days.

A message flow that turns chats into sales
| Stage | What to do | Example |
|---|---|---|
| Welcome | Say who you are and how you can help | "Hi, welcome to X. We answer size, stock and delivery questions." |
| Quick questions | Turn the 2–4 most common questions into buttons | "What are the prices?", "Can you ship today?" |
| Qualify | Clarify need and budget with short questions | "Which model are you interested in?" |
| Offer and close | Give a clear price, payment and delivery | Order summary and payment link |
| Follow-up | A policy-compliant reminder for unanswered chats | A short message that adds value |
Budget and cost
With WhatsApp ads you pay for ad delivery on Meta; cost per conversation varies a lot by industry, region and offer. Work the budget backwards from your goal: target sales ÷ chat-to-sale rate = conversations needed. For the full method, see how to set an ad budget.
If you use the WhatsApp Business Platform (API), messaging fees may be billed on the WhatsApp side separately from your ad budget; check Meta's current WhatsApp pricing rules.
Which metrics to track
- Conversations started and cost per conversation — shown in Ads Manager.
- Reply time — how long your team takes to send the first reply.
- Chat-to-sale rate — measure it by labelling chats or logging them in a CRM.
- Cost per sale and ROAS — where real profitability shows; see what ROAS is and how to calculate it.
Common mistakes
- Running ads when nobody can reply — chats that arrive at night have gone cold by morning.
- A generic welcome message — people who type "hi" and wait tend to leave.
- Looking only at conversation count — cheap chats that never convert do not make profit.
- No follow-up — many customers who are still thinking come back after a reminder.
