Digital Marketing Essentials The free OER textbook for Introduction to Digital Marketing
Targeting before tactics.
Anyone can post. Very few can tell you who the post is for. Digital Marketing Essentials grounds every platform tactic in how people actually decide to buy, so students learn to find the right customer first and then use Meta, Google, YouTube and TikTok to reach them.

Why this book exists
The platforms can find almost anyone. Most marketers can't say who they're looking for.
You know the moment. A business owner boosts a post, spends the money, and gets likes from people who will never buy. They blame the algorithm. The algorithm did exactly what it was told. Nobody told it who the customer was.
Meta and Google can target by place, life stage, interest and behavior with a precision no marketer had a generation ago. That power is wasted without the foundations underneath it: segmentation, targeting and positioning. This book teaches those foundations first, then the platforms, so every post, ad and email has someone specific on the other end.
01
Segment
Who are the different groups in this market?
Divide a market into groups that think, need and buy differently enough to deserve different marketing.
02
Target
Which group do we serve first?
Choose the segment you can reach, win and serve, and say no to the rest, on purpose.
03
Position
Why should they choose us?
Own one clear idea in that person's mind, then build every hook, ad, page and email around it.
Interactive · Targeting Lab
Narrow the audience. Watch the waste disappear.
Add segmentation variables. Each one is a choice Meta and Google will happily make for you, if you know enough to ask.
Your target audience
2.4M
of 2.4M adults in the metro area
If you spray $500 at everyone instead
No target yet
You haven't said who the customer is, so every one of about 41.7K impressions is a guess. Pick a variable to see what that guess costs.
The ad you can now write (0 of 4 layers)
“Get fit with us!”
Written for everyone, so it speaks to no one.
Illustrative figures for teaching (a $12 CPM and rough segment shares), not platform data. Module 2 teaches how to size a real segment.
Inside the book
Follow the customer, from first scroll to loyal advocate
Eight modules in four parts trace the buyer's path: understand how people decide, design the strategy, earn and buy attention, then turn attention into loyalty and prove what worked.
Part I
Discover
Understanding the Modern Buyer
See how people really decide to buy now, then learn exactly who you are trying to reach before you spend a dollar or post a word.
Part II
Design
Building the Strategy
Decide why anyone should choose you over everything else in their feed, then build the owned home base where customers find and trust you.
Part III
Reach
Earning and Buying Attention
Earn attention on platforms you don't control, and learn when it is worth paying for it, using the targeting the platforms already give you.
Part IV
Grow
Turning Attention into Loyalty
Turn strangers into subscribers, subscribers into customers and customers into advocates, then prove what worked and tell that story.
A modern content system
Build assets that compound. Borrow attention that spikes.
Modern marketing runs on two clocks. Long-form content you own keeps working for years; short-form content on rented platforms reaches people today. Students learn to create one pillar piece, cut it into dozens of short ones, and send the attention back home.
Long-term assets
Built once. Found for years.
YouTube videos, search-optimized pages, podcasts and your email list keep earning attention long after you publish. They compound.
- YouTube
- Website & SEO
- Podcasts
- Email list
Short-term attention
Fast reach. Short shelf life.
TikTok, Reels, Facebook and Stories reach people today and fade by Friday. They test hooks quickly and drive people back to what you own.
- TikTok
- Instagram Reels
- Stories & Shorts
The difference from a social media course: every piece starts from a chosen segment and a position. Theory tells you who and why; the platforms tell you how fast.
How every module works
Career-ready skills for everyone. Real results for those who want them.
Many students in the intro course have never run a business. Every one of them leaves with the skills employers hire marketers for. Those who want more apply each skill to a real organization and build a portfolio of work they can show.
01
Skills Track
The core of every module, for every student: the marketer's career kit, from customer research and copywriting to platform fluency, analytics and AI-assisted workflows.
02
Client Track
An optional path, woven into each chapter as sidebars, for students marketing something real: their own venture, a local small business, a campus cause or a family business.
03
Integration Checkpoint
Each module closes by connecting the skill to real work, so the semester produces marketing artifacts (maps, briefs, calendars, ads, sequences and dashboards), not disconnected assignments.
AI in every chapter
An AI advisor for every module, built to coach, not to do the work
AI runs through the whole book rather than sitting in one chapter. Each module has its own AI advisor: bring your draft, get feedback on your thinking, and keep every decision yours.
