Google has added a WhatsApp messaging button to the local panel in Google Search, sitting alongside the existing call, directions, website and share actions for some business listings. The integration was first spotted by search marketer Sachin Patel, who posted screenshots on X and to Search Engine Watch.

The new WhatsApp button appears either in place of the standard chat action or as an additional icon in the action row of the local knowledge panel. The result was replicated on multiple queries and account sessions, suggesting a broader rollout rather than a one-off test.

What does the button actually do?

Clicking the WhatsApp icon opens a pre-populated chat thread in the WhatsApp app or web client, addressed to the phone number Google has on file for the business. Searchers can then ask product, stock or service questions without leaving the messaging surface.

The move extends a thread Google began pulling roughly two years ago. At that point, Google Business Profile started prompting business owners to add a WhatsApp number to their listing. A few months ago, Google took the next step and began attaching WhatsApp numbers to listings automatically for some businesses, even when the merchant had not opted in.

How widely is it rolled out?

The original thread raised a practical concern: "I can't imagine the Apple Store has time and resources to WhatsApp with customers." Yet the result reproduces for at least two independent observers on different account sessions, which points away from a personalisation experiment and toward a wider deployment.

Google has not posted a help document or a blog entry on the change, and a formal rollout confirmation was not available at the time of writing.

Why now?

Three signals point to a deliberate strategy rather than an accidental deployment. First, Google has been investing in Business Profile messaging channels since it began asking merchants for WhatsApp numbers. Second, the local panel action row has been steadily expanding, with menu, booking and appointment links added to the original set of call, directions, website and share. Third, the appearance of WhatsApp follows Google's broader push to keep commercial intent inside its own surfaces - from product panels in image search to the call-and-message shortcuts in Maps.

What should local marketers monitor next?

• Whether Google surfaces a generic "Chat with us" label that uses the merchant's existing GBP chat number instead of WhatsApp
• Click-through behaviour on the WhatsApp button versus the call button, once Google Business Profile insights exposes it
• Any expansion to YouTube or Maps panels beyond Search
• A formal announcement in the Google Business Profile help centre or the Google Ads and Commerce blog, which has so far been absent

The integration is also worth watching because it changes the cost of a missed customer message. With the call button, an unanswered call ends in voicemail. With WhatsApp, a missed message is a permanent text thread the merchant can re-open - and a signal Google can use to score listing quality.
