Review the article on semicolons to ensure you can identify semicolons and know when to use them.
Read your text. Pause at any sentence that contains more than one independent clause (complete idea/sentence).
Are the ideas related? If so, you can use a semicolon to connect them instead of commaand. This will add variety to the structure of your sentences. You shouldn’t do this to every single sentence though, or you will have the same problem with a repeated sentence structure.
Pause at any lists as well as any sentences with connecting words like however, therefore, consequently, etc.
