The Speaker of the House is a powerful position in government. Perhaps the biggest power the Speaker has is that the Speaker decides what gets voted on by the full House.

So, if there is a bill that the Speaker doesn't like, he can absolutely prevent it from ever being voted on.

Right, and that’s true even if it would pass if it came to a vote. So if all Democrats and many moderate Republicans favor a bipartisan bill, the SotH can still stop it.

The SotH also makes committee appointments, including deciding who will chair each committee, and the chairs have a lot of delegated power.
