With your main points thought out, It's time to work on the Introduction. I advise writers to wait until this point simply because it gives them a chance to solidify their thoughts and get ready to make a memorable intro.

Like a stage actor, you've practiced your lines. It's time for that grand entrance.

I break this into 3 parts:

1. Hook
2. Transition
3. Thesis

And yes, the order is important.

First, you want to hook the reader. Look for something that gets the reader's attention and keeps them hooked.

I have a list by my desk. I think it originally came from Neil Patel. It reads like this:

1. Open with a Controversial Opening - “Contrary to popular belief...”
2. Offer the “Why” of Your Content - Focus on benefits
3. Lead with a Memorable Story
4. Get Readers Nodding by Stating the Obvious
5. Use an Analogy, Metaphor, or Simile
6. Cite a Shocking Statistic
7. Open with a Thought-Provoking Question

You might consider making such a list for yourself, too. It's quite helpful when you begin a post, even if you don't do the full outline.

Often, this part of the intro is comprised of only a sentence or two. But sometimes it needs to be slightly longer.

Of course, you don't use all of them on any post. Choose one for each post and make it grab attention.

Once you get their attention, transition to the main point of the post. Then tell the reader what you're going to give them in the thesis.

Be careful not to give everything away in the intro. You want to entice them to keep reading.

Try to create a first paragraph that shows expertise and begins a relationship with your reader.
