Search for market segments which maintain stability or demonstrate upward movement. For example:

Look at:

Commission rates (recurring commissions are gold).

Digital tools and software products provide 20–50% recurring commissions whereas physical products typically provide 5-10% commissions

Pro Tip: Combine low-cost products to generate regular purchases and expensive products to achieve substantial earnings.

Ask:

What content types do they produce?

Identify the missing elements.

What unique position can you establish to differentiate yourself?

Pro Tip: Similar web or Ubersuggest are used to spy on competitors traffic sources

Step 5: Define Your Audience

Each niche contains multiple distinct sub-groups. Understanding your target audience enables you to develop highly targeted content. Identify the age range together with gender identity and financial status and life habits and key problems of your audience.

Examples:

Finance niche → “College students in the finance niche who want to save money.”

Fitness niche → “Post-pregnancy workout seekers among new mom fitness enthusiasts.”

Tech niche → “Small businesses within the tech industry need affordable AI solutions.”

Step 6: Validate Before Going All In

Validating your niche before complete commitment is essential. You should develop multiple blog entries as well as YouTube content or social media short videos. People’s interaction through comments and link clicks will show your content value.

Another way is to build a small email list. Provide a complimentary guide that users can obtain by providing their email addresses. The number of email subscribers indicates genuine interest within your chosen niche.

Pro Tip: Having dozens of committed subscribers demonstrates your niche remains worth developing.
