One of the most important decisions you’ll make as an affiliate marketer is choosing your niche.
Your niche will determine the products you promote, the type of content you create, the audience you serve, and ultimately how much you can earn.
In this guide, I’ll walk you through the same steps and lessons I used to pick, start, grow, and sell my Bitcoin and scuba diving affiliate sites.
❤️ Follow Genuine Passion
It’s a lot easier to succeed when you actually care about the topic.
Over the decade I've been an affiliate marketer, the businesses that have survived the longest are those who follow their edge and passions.
Having experience or knowledge in the niche makes creating content faster, more authentic, and way more enjoyable.
What do you spend the majority of your days doing, or obsessing about?
There's a good chance other people do as well.
Write down some topics that come to mind.

🧠 Lean Into Your Edge
Another niche selection factor you have to consider is the type of content that works best in that space.
You're going to become a content factory. Pick a format you actually enjoy creating.
Certain niches favor different content formats.
Visual niches like fitness or scuba diving perform well on blogs, YouTube, and Instagram.
Technical or analytical niches like personal finance are better suited for blogs, podcasts, newsletters.
Love talking?
Lean into niches that do well with YouTube or podcasting.
Prefer writing?
Go with a niche that does well with blog, email, or written content.
Want to stay anonymous?
Skip niches like makeup and fitness where your face and personality are often part of the brand.
For visual niches, you need think of filming and photography logistics. Creating fitness content will require you filming inside of gyms. Digital niches allow you to screenshot and record from anywhere in the world.
⚖️ Evaluate the Affiliate Offer Landscape
Once your niche is dialed in, it’s time to research the affiliate program landscape to find affiliate offers to promote. I'd reccomend checking out my article on "Finding Affiliate Offers to Promote."
In 2025, most major brands have an affiliate or partnerships department. Worst case, shoot their support or general email and ask if they have one.
What we're looking for are high paying, high converting offers that are from reputable brands in the space. Bonus points for CPAs, recurring, or lifetime commissions.
If a product is on Amazon, you can promote it through Amazon Associates.
📈 Validate Market Demand
This isn't a deal breaker, but you'll definitely want to study the niche and its trend.
I use Google Trends to research long-term interest.
For example, we can go deeper into the fitness niche.
Something like “pilates” or “pickleball” are currently growing making them great niche candidates.
Compare this to the "woodworking" hobby which seems to be on its way out.
Picking an evergreen growing affiliate marketing niche is like buying a home in a great neighborhood.
If you're niche isn't trending up and to the right, that's completely fine, but its certainly something to be mindful of.
