Amazon Associates

Amazon Associates is Amazon's official affiliate program and the most popular starting point for beginners. You create tracking links for almost any product sold on Amazon and earn a percentage when a visitor buys through your link. Because shoppers already trust Amazon, conversion rates are typically strong.

Shopify Affiliate Program

Instead of selling products, the Shopify Affiliate Program pays you for referring new merchants who open a paid Shopify store. If your audience includes entrepreneurs, side-hustlers or e-commerce learners, a single referral can be worth far more than dozens of retail product sales.

TikTok Shop Affiliate

TikTok Shop's affiliate program lets creators tag products directly in short videos and livestreams. Viewers can buy without leaving the app, and you earn a commission set by each seller. It's one of the fastest-growing ways for creators to monetize — even with a smaller following.

CommissionSet by each seller — often 10% to 30%
Requirements (US)18+, US-based, 1,000+ followers
Cost to joinFree
Best forShort-form video creators and live sellers

  • In-app checkout means less friction
  • Free product samples from many sellers

Cons

  • Follower and eligibility requirements
  • Results depend heavily on content and the algorithm
  • Availability and rules vary by country

Tips to get your first commissions

What separates people who earn from people who quit after a month.

Start with one platform

Master one traffic source (a blog, YouTube or TikTok) before spreading yourself thin.

Answer buying questions

"Best X for Y", "X vs Y" and "Is X worth it?" content attracts people ready to buy.

Always disclose

The FTC requires a clear disclosure whenever you use affiliate links. It also builds trust.

Diversify programs

Rates change. Combining two or more programs protects your income from a single policy update.

Be honest

Only recommend products you'd stand behind. Trust is what drives long-term conversions.

Track everything

Use separate tracking IDs or campaigns per page or channel to see what actually earns.

Frequently asked questions

Do I need a website to become an affiliate?

Not always. Amazon and eBay accept many social channels, and TikTok Shop is entirely in-app. Shopify generally expects an established content platform. A website does make you more independent of any one social network.

How much money can I make?

It varies widely. Most beginners earn little in the first months while they build traffic. Income depends on your niche, audience size, content quality and the commission rates of the products you promote. See our Earnings Disclaimer.

Is it free to join these programs?

Yes. Amazon Associates, eBay Partner Network, the Shopify Affiliate Program and TikTok Shop Affiliate are all free to join. Be cautious of anyone charging you to "get approved".

Can I join from outside the United States?

Amazon and eBay run programs in many countries. Shopify accepts international affiliates. TikTok Shop availability depends on your country. Check each official site for your region.

How do I get paid?

Each program pays on its own schedule, usually by direct deposit, PayPal or gift card, once you reach the minimum payout threshold.
