Marketing Intelligence
The power of affiliate marketing starts with you. After all, you make it much easier for people to take the plunge and buy when you back a product or service.
Beyond supporting valuable products, affiliate marketing can benefit affiliates and even customers (in some niches). In order to really make money online with an affiliate marketer, you need to find a lucrative niche that makes sense for you.
So, what are the best affiliate marketing niches for you to bring in the most passive income? Here we’ll help you answer that question, but first, let’s take a deeper look at affiliate marketing.

Affiliate marketing is the process of promoting products or services and earning a commission. Bloggers, marketers, and businesses can use affiliate marketing to showcase products they enjoy using.
Depending on the niche, the degree of involvement of either of these parties changes. For instance:
In the beauty industry, consumers generally know that some brands offer discounts through their affiliates. So they will sometimes go the extra mile to find an affiliate website link and land a better deal. Meanwhile, in the SaaS industry, the competition among software vendors is so intense that they’ll aim to provide the most appealing deal to get you (the affiliate) to promote their tool over others – because it’s worth it.
A niche generally describes an industry of similar products or services that attracts the interest of a particular set of people.
Start with industries you’re already active in and you are known for. List the tools and services you use the most and find valuable. Is Canva your go-to for creating designs for your social media posts? That’s “graphic design apps” for you. Crazy about Grammarly? That’s the super competitive “blogging tools.”
Other classic sources to utilize for ideation are Pinterest and Amazon’s extensive department directory.

Remember, to focus on niche ideas and sub-niches that are targeted for your expertise and audience. If you focus on a popular niche that is also targeted, you can present yourself as more of an expert and build more trust, by creating tutorials and blogging. This will help you develop your online business in a focused way and maximize your payouts.
You also should pay attention to what’s trending in this research phase. The most effective way to do this is with keyword research with a tool like Similarweb. You can identify the top trends and related keywords to help guide your research. If you are specializing in a micro-niche that is already losing relevance, you want to check for related keywords and trending keywords to help you identify related terms, but more profitable niches. This an experience many affiliate marketers faced when the first pandemic hit and the global economic environment did a total one-eighty.
Just because a niche is out there doesn’t mean people are actively looking for it. You can use Google Trends to see what consumers need and how their preferences change in time:

Here’s an example of a seemingly up-and-down trend that has maintained its influence and interest over the past five years

This helps you prioritize which niches you want to target first, saving you time in the long run.
Once you’ve got a better idea of which general industries you’re interested in turning to for your affiliate marketing strategy, you can take a deeper dive into your specific industry’s trends.
Similarweb’s Industry Analysis feature provides an up-close look at the general industry traffic, top-performing websites, and even device distribution so you’ll know when it’s time to up your mobile game.

The tool also provides a great starting list of industry players that might have their own affiliate program. Run these market trend analyses regularly whenever a new economic, social, or political change could impact month-over-month traffic and interest.
Not all niches are created equal though. Competitive industries can bring in huge profits but it can take years to land a top 10 position on Google’s search results page (SERP) or within YouTube’s listings.
A profitable niche is also one with active customers who make recurrent purchases. This lets you as an affiliate marketer also sell more and grow your revenue.
This said it’s the low-competition niches that you’ll find easier to compete for. As an added bonus, the fewer the resources on these topics, the higher the chance is for someone to make a purchase via your link.
Let’s go through a series of potential niches and evaluate how you can profit from them:
If you’ve narrowed down your list of niches, it’s time to assess their profitability factors:
There are two key factors to consider when doing the actual SEO keyword research:
To get started, create your first list of keywords. You can go over to Amazon to see which keywords vendors use in their product titles or drop a starting keyword into a keyword research tool like Similarweb.
The Keyword Generator will provide a comprehensive list of related and trending keywords along with question queries. Compare the volume and trend growth for each one of them before adding them to your final affiliate marketing keywords spreadsheet. You can then prioritize these keywords based on search volume, real click rates, paid vs. organic clicks, SERP competition, and more.
Run your website through Similarweb’s competitive analysis tool to find new competitors and get insights into their own strategies.
Here’s what to focus on:
These benchmarks will help you assess whether a niche is worth going for or the competitive landscape is out of your reach for the moment.
Using Similarweb‘s Referral and Affiliate Research tools, you can go through this five-step process, and evaluate potential affiliate partnerships.
But what if you’re searching for affiliates yourself?
This digital marketing intelligence platform also works if you’re looking for new referral (and link) opportunities for your brand. Analyze the fit of future partners by researching their traffic sources, top keywords, paid efforts, and audience engagement level.
Review your partners’ outgoing traffic to spot competitors that already get traffic from them. You can use this information to find better-performing referral opportunities (by traffic quality) or renegotiate your current affiliate partnerships and programs.
