Case Studies: Bloggers Making 6-Figure Revenue via Courses
Not every course creator starts the same way. The three case studies below show three very different paths to the same goal: a blogging business that funds itself through paid digital products.
One built a personal brand around rapid, aggressive growth. Another built a slow-and-steady authority site over more than a decade.
The third turned a life of full-time travel into a prolific library of ebooks and courses. All three ended up teaching what they learned.
Case Study 1: Adam Enfroy — From Zero to a Course Called Blog Growth Engine
Background: Adam Enfroy launched his blog, AdamEnfroy.com, in 2019 after working in digital marketing roles.
Rather than treating it as a hobby, he approached it like a startup from day one heavy on keyword research, SEO, and a deliberate content plan.
In his first 17 months of blogging, he grew his monthly traffic from zero to over 500,000 visitors.
Multiple independent reviews say his monthly revenue rose from nothing to six figures in about the same time.
He earned this mostly through affiliate partnerships with software and business tools.
The Product: That growth story became the foundation for Blog Growth Engine (BGE), a paid course and community he co-created with fellow blogger Colin Shipp. The program combines an online course, coaching, and community.
It helps students build and make money from a blog mainly through affiliate marketing. The course includes more than 51 training videos alongside one-on-one coaching support.
Breakdown of the business model:
- Front-end offer: A single flagship course rather than a large product suite, priced at a premium point (reviews place it in the $1,000+ range).
- Traffic engine: Adam’s own blog and a YouTube channel he began publishing to seriously in 2021, which had grown to over 222,000 subscribers — a second content channel feeding the same funnel.
- Retention layer: Weekly live Q&A calls and a coaching team of successful past students, rather than one-on-one time with Adam himself, which keeps the coaching model scalable.
- Monetization mix: Course sales plus his own ongoing affiliate income from the blog itself — he continues to monetize the same way he teaches.
Key takeaway: Adam’s case study is a lesson in documenting your own results as the marketing asset.
The course sells because the instructor’s own numbers are the proof, and the funnel (blog → YouTube → email list → course) mirrors exactly what students are being taught to build.
Case Study 2: Anil Agarwal — BloggersPassion and the Long Game
Background: Anil Agarwal took a much slower path. He started a few early blogs on Blogspot and earned modest AdSense income, then launched a site called Scope for Money in 2008, which he later sold.
In 2010 he launched BloggersPassion, and for the first several years it struggled for traction because it lacked a clear content focus. A content-strategy shift in 2016 changed the trajectory, and by 2018 he was able to leave his job to blog full-time.
The numbers: BloggersPassion grew from about $100 a month to over $10,000 a month. The blog made over $225,000 in 2022 alone.
It averaged about $18,000 a month that year on 2.6 million annual page views. The bulk of that revenue comes from affiliate marketing, alongside selling his own ebooks, brand collaborations, and sponsored reviews.
The product suite: Unlike a single flagship course, Anil built a layered set of digital products:
- A free lead magnet in the form of short, no-cost email courses (a 7-day SEO course and a 10-day blogging course) designed purely to grow his email subscriber list.
- Paid ebooks, including Zero to $10K, a structured guide to reaching a full-time blogging income, sold with a 30-day guarantee.
- A 100-day blogging course aimed at complete beginners, positioned as an affordable, structured mentorship path rather than a high-ticket program.
Breakdown of the business model:
- Funnel structure: Free short-form email course → nurture sequence → low-cost ebooks → higher-priced course, a classic ascension model rather than one big front-end offer.
- Traffic engine: Roughly 80% of the blog’s traffic comes from organic search, supported by a Facebook group that grew past 18,000 members and doubled as a feedback channel for product ideas.
- Affiliate concentration: A single affiliate partnership, with SEO tool Semrush, has contributed more than $459,000 of BloggersPassion’s total historical revenue — a reminder that a well-chosen affiliate program can outperform an entire product line.
- Diversification: Revenue doesn’t rely on the course alone; ebooks, sponsorships, and affiliate income all run in parallel, which insulates the business against any single channel underperforming.
Key takeaway: Anil’s case study shows that a course doesn’t have to be the only — or even the primary — revenue goal.
Making a group of low-cost, easy-to-make digital products can work better than one expensive course launch.
This works well if you have a strong base of organic search traffic. This is especially true in a crowded niche like blogging-about-blogging.
Case Study 3: Ryan Biddulph — Blogging From Paradise’s Volume Model
Background: Ryan Biddulph’s story starts with a layoff. After he lost a security guard job in New Jersey, he started blogging to build an income he could run from anywhere. He eventually became a full-time digital nomad.
He lived and blogged from places like Bali, Thailand, Cambodia, and Costa Rica for over ten years. He did not try to get one viral hit.
Instead, he grew his business by publishing a large number of articles. He has written over 10,000 articles on his blogs and for clients during his career.
The Product Suite: Blogging From Paradise doesn’t lean on a single flagship course. Ryan built a large and growing library of low-priced ebooks. These titles talk about blogging mindset.
They also cover income strategies. They cover networking. They report on his island-hopping lifestyle. He also offers blogging courses and freelance writing and coaching services.
New titles are added on a steady cadence rather than launched as one-off events, so the catalog itself becomes a recurring revenue engine.
Breakdown of the business model:
- Top of funnel: Heavy free content output blog posts, guest posts, and especially blog commenting on other established blogging sites, which built visibility and backlinks long before paid ads or SEO tools were part of the equation.
- Ascension path: Ryan describes his own approach as creating and connecting publish free content until an audience trusts you, then layer in ebooks and courses for passive income, then add freelance services like writing or coaching for less passive but higher-margin income.
- Product cadence over product size: Instead of one expensive course, the model relies on many small, affordable digital products, which lowers the barrier to a first purchase and turns repeat buyers into a steady revenue base.
- Networking as marketing: Endorsements and connections with established names in the blogging and marketing space acted as a distribution channel, extending reach without a paid ad budget.
Key takeaway: Ryan’s case study is a counterpoint to the single-flagship-course model. A freelance blogging background plus many small digital products can add up to a similar income. Free content and steady networking do the hard work that a large ad budget would usually do.
What These Three Have in Common
They have different prices and different schedules. But they use the same basic design.
- Free content built the audience first. None of the three sold a paid product before they had traffic and trust.
- Each product was a translation of the creator’s own results, not a theoretical framework — the instructor’s story is the marketing.
- Multiple revenue streams run side by side. Affiliate income, course sales, ebooks, and freelance services rarely replace one another; they stack.
- List and community growth were treated as infrastructure, not an afterthought — all three built lead magnets, ebooks, or free courses specifically to fuel later launches.
If you want to model your own course business on one of these, pick the version that fits your resources and patience.
Adam’s path compresses years of growth into a fast, high-investment sprint built around one premium course.
Anil’s path spreads the same outcome over ten years with lower-risk moves across a small product suite.
Ryan’s path trades a single big launch for steady publishing and a wide catalog of small, affordable digital products.
Note: The figures above come from public interviews, income reports, and third-party course reviews. These numbers vary somewhat. Treat them as examples of scale and growth, not as audited financials.
