WhatsApp links: click-to-chat, previews and the forwarded message

WhatsApp is the only major channel where you cannot see anything. No opens, no per-recipient clicks, no forwards, no read receipts you are allowed to aggregate. It is end-to-end encrypted and it is meant to be opaque.

That makes the link the only instrument you have, and it makes what you put in the message unusually important.

The click-to-chat link, correctly formatted

wa.me/919876543210 opens a chat with that number. Full international form, no plus, no spaces, no dashes, no leading zeros. wa.me/919876543210?text=Hi%2C%20I%20saw%20the%20poster opens the same chat with a message already typed.

The pre-filled text is the useful half and almost nobody uses it well. A message that already says "Hi, I saw the poster at the station" tells you the source of the enquiry in the first line of every conversation, without any tracking at all. Change the text per placement and your inbox sorts itself.

The URL-encoding is where people come unstuck: a space is %20, a comma is %2C, a newline is %0A. Get one wrong and the link either drops the message or fails to open. Build it with a tool rather than by hand.

Why shorten a wa.me link at all

Because wa.me/919876543210?text=Hi%2C%20I%20saw%20the%20poster%20at%20Andheri%20station is 76 characters of noise on a poster, and because you cannot change it once it is printed.

gc.mw/chat is ten. It points at the wa.me link, so the behaviour is identical, and the number behind it can change when the sales phone changes, which happens more often than anyone plans for.

It also gives you a count. WhatsApp will never tell you how many people opened a chat from that poster; the short link will.

A worked example: separating the send from the forward

A clinic sent a monthly broadcast to about 1,400 patients and could never explain why enquiries kept arriving weeks later.

They put two codes in circulation. gc.mw/apr went in the broadcast message. gc.mw/aprp went on the printed slip handed out at reception, pointing at the same booking page.

The broadcast code took a sharp spike on send day, then a long tail that kept going for three weeks at a level far above zero. That tail is forwarding, messages passed into family groups, one recipient at a time, entirely invisible in any dashboard except the click count.

Roughly a third of the month's clicks arrived after day three. The clinic moved its follow-up call script to start on day five instead of day two, because that is when the forwarded audience was actually reading.

The QR on the counter

A click-to-chat link inside a QR code is the highest-conversion piece of print a small business can make. Someone points a phone at a card and lands in a chat with a message already typed. No form, no app, no typing.

Every gc.mw link has its QR at gc.mw/chat.qr for a PNG and gc.mw/chat.svg for print. Scans are recorded separately from clicks because the encoded URL carries a ?qr marker, so the counter card and the broadcast message never blur into one number, and if you have ever tried to justify printing 500 table cards from a single total, that split is the missing evidence.

Trust, which is the real constraint in India

Forwarded scam links are an everyday experience for most WhatsApp users here. A random code from a shortener with a mixed reputation gets fewer taps than a legible one, and both get fewer than a link on a domain the recipient recognises.

Our alphabet drops 0, O, I and l so a link read aloud on a call cannot be mistyped, and custom aliases on Pro let you use words. If your links go to strangers rather than customers, put them on your own domain, the custom domain links page has the two DNS records, and see the link-in-bio product page for the page that holds the chat link alongside everything else.
