What are Click-to-WhatsApp Ads?
Click-to-WhatsApp ads are a type of advertisement on Meta platforms (Facebook, Instagram) that allow users to initiate a WhatsApp conversation directly from the ad.Why?
- Conversations started from these ads are free.
- You have a 72-hour window for conversations instead of the usual 24 hours.
- The conversions are genuine: you interacted with a real person, making it much less likely that a bot was involved.
- Data captured in lead forms or other Facebook ads are auto-filled with stored information, which might not be the client’s most recent data. In contrast, on WhatsApp, you have their current phone number for sure.
How They Work
These ads appear on Facebook and Instagram and include a call-to-action button that, when clicked, opens a WhatsApp chat with your business. This enables immediate and personalized communication with potential customers.Example
Imagine a user scrolling through Instagram and seeing an ad for a new product. They have questions and click the “Message on WhatsApp” button, which opens a chat with your business where they can get instant answers.
