Put WhatsApp Where the Offer Is
A floating button helps. It is not enough on its own. Repeat WhatsApp next to the offer on Home, on each service page, and on Contact. The buyer should not hunt for a green icon after they decided.
Use a label that names the job: “WhatsApp Us,” not a mystery circle. The Contact page still holds hours, email, and the legal entity. WhatsApp is the fast path, not the only record of the business.
Prefill So You Know the Page
A blank chat makes the buyer type from memory. Prefill the first line with the page or the offer: the service name, the URL, or the campaign. You will reply faster and you will know which page worked.
Keep the prefill short. A novel in the compose box looks like spam. One sentence is enough. Change the text per landing page when ads are live.
Show Hours and Who Replies
If nobody reads chat after 6pm, say so near the button. “We reply in business hours” beats a typing ghost that never comes. Name a person or a desk if the brand is small enough.
Do not claim 24/7 unless that is the actual roster. A missed chat is worse than honest hours. Put the same hours on Google Business Profile so the two surfaces do not argue.
When a Form Still Helps
Use a short form when the job needs files, a date, or a written record: tenders, clinic intake, school applications. WhatsApp still sits beside it for people who will not type a form on a bus.
Do not ask for ten fields before a quote. Name, contact, and the job are enough to start. Email can copy the same message if you need a backup.
Do Not Hide It in the Footer Only
Footer WhatsApp is a fallback. The conversion path lives in the hero and next to proof. If the only tap is behind Contact Us, you already lost the tired buyer.
If you are also running ads, the landing page must use the same number and the same promise. Check the URL with how to check a site before Google Ads.
