To not write a bad novel, focus on having a clear beginning, middle, and end. Make sure your story has a purpose and that the events flow logically. And don't rush the development of characters and their relationships.

One big no-no is having a confusing plot. Make sure your story flows logically and readers can follow easily.

Well, first of all, you should have a clear plot in mind. Don't start writing without a plan or you might get lost in the middle.
Read a lot of well-written fiction to understand what works and what doesn't. Also, get feedback from others and be willing to revise.
A big mistake is not using subtext effectively. Dialogue that is too straightforward can be boring. Subtext adds depth. Also, don't overuse dialogue tags. Sometimes it's better to let the dialogue flow without constantly reminding the reader who is speaking. And make sure the dialogue is appropriate for the time period and setting of the story. If it's a historical story, modern slang would be out of place.
