We've written more specifically about writing captivating introductions in the post, "How to Write an Introduction [Quick Tip]," but let's review, shall we?

First, grab the reader's attention. If you lose the reader in the first few paragraphs -- or even sentences -- of the introduction, they will stop reading even before they've given your post a fair shake. You can do this in a number of ways: tell a story or a joke, be empathetic, or grip the reader with an interesting fact or statistic.

Then describe the purpose of the post and explain how it will address a problem the reader may be having. This will give the reader a reason to keep reading and give them a connection to how it will help them improve their work/lives.
