WhatsApp Ads are Meta ads that run on Facebook and Instagram and, instead of sending people to a website, open a WhatsApp conversation with your business. You create them in Ads Manager by choosing WhatsApp as the destination, and they perform best when someone replies within minutes and every chat is logged as a sales opportunity. Here are the requirements, the step-by-step setup, the costs and the metrics that actually matter.
What click-to-WhatsApp ads are
A click-to-WhatsApp ad looks like any other ad in the feed, stories or reels, with one difference: its button says something like “Send WhatsApp message”. When tapped, WhatsApp opens with a chat addressed to your number and, usually, an opening message already typed.
One common misconception is worth clearing up: these ads do not show up inside WhatsApp chats. They run on Facebook, Instagram and other Meta placements; WhatsApp is the destination.
Ad with a wa.me link versus ad with a WhatsApp destination
You could paste a WhatsApp link into a traffic ad, but you lose almost all the advantages:
| Aspect | Traffic ad with a wa.me link | Ad with a WhatsApp destination |
|---|---|---|
| Meta optimization | Goes after clicks | Goes after conversations, leads or sales |
| Greeting and suggested questions | No | Yes, set up in the ad |
| Reporting in Ads Manager | Link clicks | Conversations started |
| User experience | May pass through the browser | Opens WhatsApp directly |
Benefits of sending ads to WhatsApp
- A conversation instead of a form: customers ask in their own words and you can handle objections on the spot.
- A shorter sales cycle: you can quote, share your catalog and collect payment in the same chat.
- Real contact data: the phone number comes with the conversation, no forms filled with fake details.
- Later follow-up: with the customer’s consent, you can reopen the conversation with templates approved by Meta.
- A natural fit for Latin American markets, where much of the buying relationship already happens on WhatsApp.
The flip side: a WhatsApp ad creates human work. If nobody replies quickly, you are paying for conversations that go cold.
Requirements before you build your campaign
- A Facebook Page for your business and, if you will advertise on Instagram, a linked Instagram professional account.
- A WhatsApp Business number (app or official API) connected to that Page.
- An ad account in your Meta business portfolio, with a payment method.
- A response plan: who answers, during which hours and with which messages. This matters as much as the ad itself.
If you are unsure whether the app or the API fits this use case, a simple rule helps: if you expect more conversations than one person can handle from a phone, start with the API.
How to create a click-to-WhatsApp ad step by step
Exact option names change with Meta updates, but the general flow in Ads Manager looks like this:
- Create a campaign and choose the objective. The main objectives that support WhatsApp as a destination are Engagement, Leads and Sales (we explain which to pick below).
- At the ad set level, choose where the conversion happens: messaging apps, then WhatsApp. Select the Page and the connected number.
- Set the budget and schedule. Run ads during the hours your team can respond, or make sure you have an automatic reply after hours.
- Define the audience: location, age and interests, or let Meta broaden targeting if your creative already filters for the right customer.
- Pick placements: Facebook and Instagram feed, stories and reels tend to work well for this format.
- Build the ad: image, video or carousel, primary text and headline.
- Set up the greeting: the welcome message people will see and the suggested questions they can tap to start (for example, “How much is it?”, “Do you ship to my city?”).
- Review and publish. Run a test from your phone to see the full experience.
You can also boost an existing post from Facebook, Instagram or the WhatsApp Business app with WhatsApp as the destination. It is faster, but gives you less control over targeting and measurement.
Which objective to choose
| Objective | What it does | When to use it |
|---|---|---|
| Engagement | Maximizes conversations started | To get started, validate offers or when your team can filter volume |
| Leads | Looks for people more likely to become leads | When volume is fine but quality is low |
| Sales | Optimizes toward purchases | When you can send Meta the sales closed in chat |
The logic is to move left to right: volume first, then quality, then sales. To optimize for sales, Meta needs to know which conversations ended in a purchase, which means connecting your CRM to Meta (for example, through the Conversions API).
How much WhatsApp ads cost
There are two separate costs, and it pays to keep them apart:
- The ad: you pay Meta through the auction, based on your budget, audience and competition. There is no fixed rate per conversation.
- WhatsApp messaging: if you use the API, Meta charges per delivered message based on category and country, with changes that took effect on October 1, 2026.
The good news for advertisers: when a conversation starts from a click-to-WhatsApp ad, Meta opens a free 72-hour window for the messages you send through the API. Use it to qualify, quote and close with no messaging cost, and check the current terms in Meta’s documentation. For the rest of your sends, estimate costs with the WhatsApp API pricing calculator.
Best practices for ads that sell
- Reply in minutes, not hours. Buying intent cools fast. If you cannot cover every hour, use a chatbot or an AI agent for the first reply.
- Let the creative prequalify: show a price or range, your service area and what people get when they write. Fewer browsers, more buyers.
- Use helpful suggested questions: the ones your team answers every day.
- Prepare quick replies for the five most frequent questions, plus a qualification script.
- Split campaigns by offer so you know which product drives quality conversations.
- Follow up without being pushy: many sales close on the second or third touch. See how to handle customer follow-up on WhatsApp and use approved WhatsApp message templates once the 24-hour window has closed.
- Test one variable at a time: creative, audience or offer, not all three at once.
Metrics to track
Ads Manager shows you the cost per conversation started. It is a good start, but it does not tell you whether you are making money. Track the whole chain:
| Metric | What it tells you | Where to measure it |
|---|---|---|
| Cost per conversation started | How much each chat costs | Ads Manager |
| First response time | Whether your team answers in time | CRM or support inbox |
| Qualification rate | What share of chats are real prospects | CRM |
| Close rate | What share of chats end in a sale | CRM |
| Cost per sale and ROAS | Whether the campaign is profitable | Matching Meta Ads with your sales |
Without a CRM that logs the stage of every conversation, the last three rows turn into guesses. To go deeper, see why a WhatsApp CRM is what lets you scale this channel.
Common mistakes
- Running ads without a team or automation to reply. The fastest way to burn budget.
- Optimizing for conversations forever. If quality is low, move to Leads or Sales.
- Using a single personal number answered from one phone by several people.
- Not tagging the source of each conversation, so you cannot tell which ad sold.
- Judging the campaign only by cost per message. One pricier chat that closes beats ten cheap ones that never buy.
- Forgetting Instagram: the same ads can run there, and you can complement them with a WhatsApp link for Instagram in your bio and stories.
