Lifelink is a static ability. If a source with lifelink—usually a creature—deals damage, combat or otherwise, its controller gains that much life at the same time. The reminder text puts it simply: damage dealt by this creature also causes you to gain that much life. It isn’t a separate trigger you can respond to, and multiple instances of lifelink don’t stack; one is enough.
In play, lifelink turns damage into a life buffer. Attacking or blocking with lifelink creatures makes races harder for opponents and can undo several turns of chip damage with one big hit. Even a small lifelink creature gains a little life each turn, helping you stabilize while still applying pressure.
