Preheat grill to high (450–500°F / 232–260°C) and clean grates with a grill brush.
In a small bowl, mix herbs, olive oil, lemon juice, garlic, salt, and pepper to make the herb rub.
Pat salmon fillets dry with paper towels.
Brush herb rub evenly over both sides of the salmon.
Place salmon on the grill (skin-side down if skin-on), directly on the grates.
Sear with lid closed for 4–5 minutes without moving, until skin is crispy and sides start to cook.
Flip carefully and cook 3–4 minutes more, until salmon flakes easily; internal temp ~145°F (63°C).
Rest 1–2 minutes (optional), then serve with lemon wedges.
