Summary

• Use a wa.me link with a prefilled message: the customer only has to tap send.
• A different message on each page tells you where the conversation came from.
• The top, the end of each section and a discreet floating button on mobile cover almost everything.

Most visits to a local business website come from a phone. And on a phone, the shortest path from “I like this” to “I’ll get in touch” is almost always WhatsApp. A well-placed button covers that path in one tap. A badly built one opens an empty chat, and the visitor gives up before typing anything.

#The pre-filled message does half the work

WhatsApp lets you open a chat with text already written. It’s the wa.me link with the number and the message:

https://wa.me/5555999999999?text=Olá!%20Vim%20pelo%20site

When the visitor taps the button, the app opens with the text in the message field, and all they have to do is send it. That takes care of the hardest moment in any contact: the first sentence.

#One message for each page

The same button can send different messages depending on where the visitor is. On a product page, the message already names the product. On the quote page, it already asks for a quote. That way whoever answers knows the topic before replying, and the customer doesn’t have to repeat themselves.

• Homepage: “Hi! I found you through the website and I’d like more information.”
• Product page: “Hi! I’m interested in the Type 1 flour, 25 kg bag.”
• Quote page: “Hi! I’d like a quote for a renovation.”

#Where to put the button

Three spots cover almost every case: at the top, for people who arrive already decided; at the end of each important section, for people who decide as they read; and a floating button in the corner of the phone screen that follows the scroll. The floating one has to stay discreet: it can’t cover the content or the button for another action.

#Business account and first reply

Use WhatsApp Business. It shows the company name and profile, lets you set greeting and away messages, and gives you quick replies for the questions that keep coming up. If a message arrives after hours, an automatic reply saying when you’ll be back beats silence.

#Know where each chat came from

When each page sends a different message, you start to see which page brings in the most chats. Add the site’s analytics and you get the real path your customers take: a Google search, a page visit, a tap on the button, a chat. With that path in hand, you can improve the site based on what works instead of guesswork.

#What to avoid

• A button that opens WhatsApp Web on a phone instead of the app.
• The personal number of someone who goes on vacation.
• The same generic message on every page.
• A floating button sitting on top of a form’s submit button.

A WhatsApp button looks like a detail, but it’s often the last step between a visit and a customer. Design that step with the same care as the rest of the site.
