Click-to-WhatsApp ads and site buttons routinely outperform contact forms on mobile because they remove every step between intent and conversation. The lead arrives warm, with an open thread you can nurture.
The funnel that works: a WhatsApp CTA on high-intent pages, an instant auto-greeting that sets response expectations, a short qualifying sequence, and a calendar link once fit is confirmed. Response time under five minutes doubles close rates.
Treat the channel with respect — no broadcast spam, clear opt-outs, business hours honesty — and it becomes the highest-converting entry point on your site.
