Most of the local clients I work with (clinics, repair services, small shops) get almost all their leads from a WhatsApp button or a tap to call link, not from forms. In GA4 I usually set a click event on wa.me and tel: links and mark it as a key event, then import it to Google Ads. The problem is a click is not a real lead, people tap and never send the message. Some clients see 40 clicks and maybe 10 actual chats. How are you handling this? Do you just optimize for clicks and accept the noise, use call tracking numbers, or something else like asking the client to log real leads and uploading them as offline conversions? Curious what actually worked for small budgets.
