How to Make Money with Muscle Building Supplements

I struggled for years to make consistent affiliate commissions. The formula I found success with and continue to use today is creating niche websites.

A niche website works extremely well for promoting affiliate products. It is due to the content they contain and the free traffic the content generates.

Initially, I did not know how to earn income with a niche website. I didn’t want to waste time figuring it out on my own so I searched for an online course and found this one.

Following the training and taking action on what I learned is what helped me to transition out of a full-time job into working on my website full-time.

One of the great things about niche websites is that they are beginner-friendly, low-cost, and easy to maintain.

Choosing a Subniche

The first step to creating your niche website is to choose a niche. In this case, it will be in the muscle building niche.

It is completely fine to stay in the general muscle building niche. However, I’ve found that subniches tend to work better in terms of targeted web traffic.

Example of subniches for this niche may include:

  • muscle building for women
  • building muscle over 40
  • bodybuilding for skinny guys
  • vegetarian muscle building

See how much more targeted you can get when you subniche? By doing so, you’ll have less competition in the search engines like Google.

Also, when you do receive traffic, it will be highly targeted which increases the likelihood of people clicking on your affiliate links and buying products that you recommend.

Creating Relevant Content

Content creation is the key to receiving targeted web traffic. The content that you create will be in the form of blog posts.

You’ll want to do a bit of keyword phrase research before writing new blog posts.

Think about what your target audience would be searching for. For example, they may search for products like protein powder. Opening up Google Search and typing in keywords will pull up autosuggest results.

These results will provide you with plenty of new content ideas to write about.

The goal is to write relevant content. For example, I have a blog post that ranks for the term “bodybuilding affiliate programs.”

That same article ranks on the first page of Google for relevant searches such as “muscle building affiliate programs.”

Free Targeted Traffic and Sales

Over time, all of the content that you create will eventually be indexed and ranked in the search engines such as Google.

That is the beauty of a niche website. You don’t have to pay for traffic. That means you get to keep more of the commissions that you earn.

Since your web traffic is highly targeted, it also increases your chances that a majority of your visitors will likely click on your affiliate links and buy products.

I’ve been managing niche websites for years and this online business model works.

Also, keep in mind that many of the affiliate programs listed above and others do have an approval process.

They often look for affiliates that have websites that have content related to their products.

Having a niche website increases your chances of being approved on the first try.

Closing Thoughts

The muscle building niche is a lucrative niche due to the demand for supplements. Don’t forget about the vegan protein powder affiliate programs that offer supplements for the vegan niche.

Creating a niche website is an ideal way to earn a consistent income online.
