Episode Summary
Mark opens with listener feedback from Daleep, who is stuck on niche selection. Mark addresses the anxiety head-on: picking a niche is important, but it is not a lifetime commitment. There is no magical hidden niche that will dump money into your bank account. Any niche where products are being sold represents an opportunity. The goal is to find the intersection of something you are interested in and something commercially viable.
Mark uses a blood pressure monitor example to illustrate that niches exist everywhere. You could build an entire website around blood pressure monitors, covering reviews, comparisons, how-to guides, and FAQ content. Products range from basic manual cuffs to Bluetooth-enabled devices costing over $100. The same principle applies to virtually any product category.
The niche evaluation framework has three main criteria:
Personal interest. Especially for your first site, you need to care about the topic enough to push through the inevitable difficulties. Mark's interest in youth baseball is high because he coaches his son's team and is deeply involved in the sport.
Content creation potential. Can you identify big topic areas for the niche? Within those areas, can you immediately think of specific questions and subtopics? For youth baseball, Mark identifies coaching practices, team management, equipment reviews, training techniques, and personal stories as major content categories, each with dozens of specific topics.
Commercial viability. Two specific tests: First, are there products on Amazon with three-digit price tags? Second, are people buying them? Products with 50 to 300 reviews indicate strong sales volume, since only a tiny percentage of buyers leave reviews. Additionally, check if Google shows ads when you search niche-related terms. Advertisers only spend money when they are making money.
Mark recommends picking one niche and working on it from start to profit rather than starting 14 different sites simultaneously. If a niche meets all three criteria, go with your gut. You are not passing this niche down to your grandchildren.
Key Takeaways
- Do not stress about picking the perfect niche. It is important but not irreversible.
- There is no magical hidden niche. Any category where products are being sold is a potential opportunity.
- Evaluate niches on three criteria: personal interest, content potential, and commercial viability
- Products should have three-digit price tags to generate meaningful affiliate commissions
- Amazon review counts indicate real buyer volume. 200 reviews may represent 20,000 purchases.
- Google Ads appearing for niche keywords confirm that marketers are making money in the space
- Pick one niche and work it from start to profit. Do not spread yourself across multiple sites.
What's Changed Since This Episode
Mark recorded this in September 2016. The niche selection framework remains sound, but the tools and competitive landscape have evolved.
Niche research tools have become dramatically more powerful. In 2016, niche evaluation required manual searches across Amazon, Google, and competitor sites. In 2026, tools like Semrush, Ahrefs, and Jungle Scout provide comprehensive market data including search volume, competition scores, keyword difficulty, and estimated traffic potential. AI tools can analyze a niche's viability in minutes.
Amazon's affiliate commission structure has changed significantly. Amazon reduced commission rates across many categories in 2020, with some categories dropping to as low as 1%. This has pushed many affiliate marketers toward diversifying beyond Amazon to include direct brand affiliate programs, ShareASale, Impact, and other networks that offer higher commissions.
The competitive landscape is more crowded. More people have built niche affiliate sites since 2016, and Google's Helpful Content updates have raised the bar for what content ranks. Sites need to demonstrate genuine expertise and first-hand experience (E-E-A-T) rather than simply aggregating information from other sources.
Content formats have expanded beyond blogs. In 2016, niche sites were primarily blog-based. In 2026, successful niche site builders often combine blog content with YouTube reviews, TikTok short-form video, email newsletters, and podcast content. Multi-format presence builds authority faster and reaches audiences where they prefer to consume content.
Mark's core framework, choose something you are interested in where there is content to create and products to sell, remains the right starting point. The specific tools and tactics have evolved, but the decision-making process is still valid.
