Something else you may consider along with this general advice is characterization and character hooks.
Characterization is making a character unique and continuing to build on their personality and uniqueness throughout the story.
A character hook helps build characterization, especially with minor characters where characterization isn’t as strong. A hook is something memorable that will help a character stick in a reader’s mind. When a character comes into scene, you can use their hook to help remind the reader who the character is and to strengthen characterization. Hooks can be things like a description, dialogue style, or something that always appears in scene with the character.
In the book Save The Cat! Blake Snyder refers to hooks as giving each character “A Limp and an Eyepatch”.
Here are some examples from one of my favorite series, Harry Potter. Hagrid has beetle black eyes, he is massive, has a wild beard, a soft heart, etc. that make him very unique. You can flip to anywhere in the books and Rowling never uses just his name in a scene. She always takes advantage of the opportunity to strengthen characterization. A more minor character, Filch, is always with his cat, which is his hook. Her books are full of characterization and hooks in every scene. The characters without hooks are the ones I tend to forget. I could never remember who Parvati Patil was, but I could remember Colin Creevey with his ever-present camera and Potter-crush.
