Most knots clamp the hook by the eye. A snell wraps down the shank, which lines the hook up with the line and makes it pull straight into the corner of the fish's mouth. That is why it is the knot for circle hooks and live bait.
A snell is better whenever the hook is doing the hooking by itself — circle hooks, live bait rigs, walleye spinners and catfish rigs. The snelled shank makes the hook rotate and set in the jaw rather than catching somewhere in the middle.
It is the wrong knot for a lure you are working with the rod. For a jig or a crankbait, a Palomar or a loop knot keeps the lure's action, which a snell would stiffen.
The wraps must be snug before you finish. Loose wraps let the hook twist under pressure, which is exactly what the snell is supposed to prevent.
Count your wraps. Five to seven depending on hook size and line. Too few and the wraps spread; too many and the knot bulks up and will not seat.
Keep wraps toward the bend. The further down the shank they sit, the straighter the pull. Wraps bunched at the eye defeat the purpose.
Use it with circle hooks. A snelled circle hook is the standard for catfish and for conserving game fish: the hook slides to the jaw and sets there without gut-hooking.
The snell only pays off with the right hook and the right rig. These are the staples.
The snell and the circle hook are made for each other. The hook rotates and sets in the jaw, which is why it is the choice for catfish and live bait.

Snelling keeps the hook in line with the leader instead of hanging off it. The hook size chart covers the hooks worth snelling, the knot strength calculator shows what it retains, and the best catfish rig guide uses it heavily.
It lines the hook up with the line so the hook pulls straight rather than sideways. That makes the hook rotate and set in the jaw instead of catching elsewhere, which is why it is standard on circle hooks and live bait.
Five to seven. Use fewer on a small hook with light line and more on a large hook, but keep the wraps snug and sitting toward the bend.
No. A snell is for single hooks with a straight shank. Treble hooks get a loop knot or a Palomar.
Not necessarily — the Palomar is one of the strongest hook knots there is. The snell is about how the hook pulls, not about breaking strain.
Yes. A snelled circle hook is the standard catfish rig, and it is also the easiest way to release a fish cleanly because it almost always hooks in the jaw.
