WhatsApp

Also known as: WhatsApp Business, Meta WhatsApp

WhatsApp is Meta's messaging app, used by people and businesses for one to one and group conversation across mobile and web. Businesses reach customers through the WhatsApp Business app for smaller teams or the WhatsApp Business Platform for programmatic messaging at scale. It functions as a support, transaction and retention channel rather than a public, indexable content surface.

What it is

WhatsApp is an encrypted messaging service owned by Meta and one of the most widely used messaging apps globally. Business use runs on two tracks: a free app aimed at small businesses with profiles, catalogues and quick replies, and an API based platform for CRM integrations, template messages and automated flows. Messaging to customers generally requires an opt in and, outside an open conversation window, approved message templates.

Why it matters

Messaging captures high intent conversations that never appear in web analytics, including questions that would otherwise be typed into a search engine. Click to WhatsApp ads give paid social a direct response route that ends in a conversation rather than a landing page, which suits considered purchases and local services. As AI assistants absorb more informational queries, owned conversational channels become a more reliable way to reach existing customers.

How it works

Teams connect WhatsApp to their CRM or helpdesk through the Business Platform, define opt in points on site and in ads, and build template messages for order updates, reminders and reactivation. Conversations are routed to agents or handled by automated flows, with handover rules for complex cases. Performance is tracked by conversation volume, response time and downstream orders, with unsubscribes watched closely because heavy templated messaging erodes trust fast.

When it applies

It applies in markets where WhatsApp is a default communication channel, and in any business where sales depend on back and forth questions, quotes or bookings. It is also relevant for post purchase updates and retention where email open rates are weak.

Examples

  • A local kitchen fitter runs click to WhatsApp ads so enquiries arrive as chats with photos attached.
  • An online pharmacy sends order dispatch and delivery updates through approved WhatsApp templates instead of SMS.
  • A travel agent uses the Business Platform to route incoming chats to the right consultant based on destination keywords.

How it is measured

  • Conversations started, by source, including click to WhatsApp ads and on site entry points
  • Cost per qualified conversation and conversation to order rate
  • Median first response time and resolution time
  • Opt in growth and opt out or block rate per campaign
