In this guide, we’ll break down everything you need to know to start earning passive income from blogging—whether you’re aiming to earn a few hundred bucks a month or build a six-figure business.

What Is Passive Income?

Passive income is money you earn with little to no ongoing effort. Think of it like planting a seed that grows into a money tree over time.

When it comes to blogging, passive income typically comes from monetizing your content so it continues to earn even after you’ve written it.

Some popular passive income sources for bloggers include:

Affiliate marketing

Display advertising

Digital product sales

Online courses or memberships

Sponsored content (with long-term value)

Step-by-Step: How to Build Passive Income Through Blogging

1. Pick a Profitable Niche

Your niche is your blog’s focus—and choosing the right one is critical.

Ask yourself:

What do I enjoy writing about?

What topics do people search for regularly?

Are there products/services I can promote within this niche?

Profitable blog niches in the U.S. include:

Personal finance

Health and wellness

Parenting

Travel

Food and recipes

Technology and gadgets

Home improvement and DIY

2. Set Up Your Blog the Right Way

To make money long-term, you need a solid foundation.

Here’s what you’ll need:

A domain name that’s short, memorable, and brandable.

A reliable hosting provider (SiteGround, Bluehost, or HostGator are great for beginners).

A WordPress site with a clean, fast-loading theme (speed matters for SEO and user experience).

3. Create High-Quality, SEO-Optimized Content

This is where the magic happens.

Every blog post should:

Solve a problem or answer a question your audience has

Include keywords people actually search for (use tools like Ubersuggest or Google Keyword Planner)

Be easy to read, scannable, and visually appealing (use headings, bullet points, and images)

Link to other helpful content on your site

Pro Tip: Focus on “evergreen” content—topics that stay relevant over time, like “How to Budget on a Low Income” or “Beginner’s Guide to Keto.”

4. Monetize Your Blog

Once your blog has a few solid posts and a trickle of traffic, it’s time to turn those clicks into cash.

A. Affiliate Marketing

Join programs like Amazon Associates, ShareASale, or Rakuten.

Recommend products or services naturally within your content.

Earn a commission every time someone buys through your link.

B. Display Ads

As your traffic grows, switch to Mediavine or AdThrive for higher payouts.

C. Sell Digital Products

Think eBooks, templates, planners, or printables.

Use platforms like Gumroad, SendOwl, or Shopify Lite.

D. Offer Online Courses or Memberships

Teach what you know.

Use platforms like Teachable, Podia, or Thinkific.

5. Build an Email List

Your email list is your golden goose.

Offer a freebie (like a checklist or mini guide) in exchange for an email address. Then, nurture that list with weekly or bi-weekly emails, sharing value and promoting your monetized content.

Tools like ConvertKit and Mailchimp make this easy.
