Here is some great information I found on Diana Urban’s blog.
When you’re revising any piece of writing — a novel, a news article, a blog post, marketing copy, etc. — there are certain words you should delete to make the text stronger and cut your word count. When I’m writing a novel, one of my last drafts focuses on cutting these useless words. Removing them helps speed up the pacing of both action and dialogue, and makes your work more polished and professional. While this might not be the ultimate list of all words you should remove, these are the ones I look for when I’m doing revisions, so I thought other writers out there would find this helpful! Also, my examples below might be exaggerated, but I hope they get the points across.
