Your link
You pick your link the first time you publish. Short is good.
Your link is the address people type, scan and tap. You pick it the first time you publish, and the builder suggests one from your page’s name.
Use Latin letters and digits, at least 3 of them, with single dots between words if you like. If a link is taken, the builder offers others.
Once your page is live, Copy and Share are on the live screen.
