How to Turn Your Existing Content (Blogs, Podcasts, Talks) into a Book

Ever feel like you’re starting from scratch when it comes to writing your business book? Here’s the good news if you’re an entrepreneur: You might already have the bulk of your book hiding in plain sight!

If you’ve been blogging, recording podcasts, holding webinars, giving speeches or presentations, or even sharing long-form social posts—almost any type of content over the years—you’ve already done a ton of the “heavy lifting.” Repurposing that existing content is the fastest way to jumpstart your book project, accelerate your writing process, and finally get your expertise in the hands of more people.

Why Repurposing Content for a Book Works for Entrepreneurs

  • Saves massive amounts of time: You’ve already created valuable material; let’s use it!
  • Spotlights your unique voice and perspective: Your past content captures your style and core messages.
  • Shows what resonates: You can see which topics got the most engagement and build your book around what your audience already wants.
  • Reduces overwhelm: Instead of facing a blank page, you start with a library of ideas, stories, and proven frameworks.

5 Steps to Turn Your Content into a Book

1. Inventory Everything You’ve Created

Start by gathering:

  • Blog posts and articles
  • Podcast transcripts or show notes
  • Webinar recordings and slide decks
  • Video scripts, talks, workshops
  • Email newsletters or even long-form social content

Don’t worry about quality or order yet; just collect everything in one place (Google Drive, Dropbox, etc.).

When I was writing my own book, since I already had SO much content, I started collecting things that weren’t already in one spot (like blog posts were already corralled) into a Google Drive folder. Sometimes it was screenshots of a social media post, or I would copy and paste, other times it was exporting transcripts of YouTube videos.

2. Batch and Categorize Your Content by Theme

Go through your content and group similar pieces. Look for recurring themes, signature frameworks, or repeat questions you answer. For me, some of this was very easy since I can usually categorize by type of marketing (website, social media, email marketing etc), yet my first book was all about mistakes that are common in marketing, so I had to get creative with how I categorized. I quickly found out that case studies were an important part of what I had, so that was another new category I created.

My Favorite Tool:
I personally use Google Notebook LM to quickly batch and organize my content. Here’s how:

  • Upload your collected materials. Each notebook can have 50 sources added, and all different types of content in one: Google docs and Slides, website URL, YouTube video link, and pasted text.
  • Let the tool cluster each group of content into topical groups
  • Review the main categories and spot repeated themes

This step isn’t about letting AI “write” your book for you; it’s about making your existing knowledge instantly visible and organized, so you can spot the gold in your own work. In fact, NotebookLM isn’t very great at writing anyway; what it is good at is compiling and summarizing information. For my own book, I had it summarize by topic, so I had one notebook for website content, one for SEO content, one for social media etc., and even one for my stats and case studies.

3. Select the Strongest Content for Your Book’s Outline

Not everything you’ve created needs to (or should) make it in. Look for:

  • Posts, episodes, or talks that got strong engagement
  • Evergreen how-tos or case studies that show your expertise
  • Stories or lessons you find yourself sharing again and again

Arrange these into a logical sequence that matches the journey you want your book to take readers on (introduction, core chapters, action steps, etc.).

Both ChatGPT and Google Gemini are good at taking the topic clusters that you found or created in NotebookLM and helping you turn them into a sensible outline.

4. Revise, Update, and Add Value

Repurposing doesn’t mean copying and pasting your existing word-for-word. Update examples, refresh statistics, and tie sections together with new transitions.

  • Add extra insights you’ve gained since first creating the content
  • Address questions or objections you hear most from clients
  • Make sure each chapter flows into the next

This is where your book starts to take shape and where your expertise shines through.

5. Fill in the Gaps and Polish

You’ll likely notice a few missing pieces or weak spots in the outline.

  • Draft new sections to bridge gaps or clarify key points
  • Add an introduction and conclusion to tie the whole book together
  • Hire an editor or book coach to help you elevate your draft into a finished, professional manuscript – we can help you with this step!

Real-World Example: My Content Batching Process

When I started working on my own book, I was overwhelmed by the thought of starting from scratch. Instead, I exported years of blog posts, workshop outlines, and even video transcripts into Google NotebookLM. The tool helped me see exactly which themes I returned to again and again—making it easy to build an outline based on my best material.

Important: I didn’t use AI to write my book, and you should not either; but the organization process saved me countless hours and made sure I never lost my unique voice or perspective.

Quick FAQ: Repurposing Content into a Book

Q: Can I really use my blog posts or podcasts for a book?
A: Absolutely! Many bestselling business books start as a collection of blogs, talks, or workshop content—revised and structured for book readers.

Q: Will readers notice if I repurpose content?
A: Not if you revise, update, and tie it together thoughtfully. Your book’s value comes from curation, organization, and the new insights you add.

Q: What if I don’t have enough content yet?
A: That’s okay! Repurposing works with whatever you have—and helps you see what to create next.
