Some days, affiliate marketing feels like learning a new language you never signed up for.
A lot of the vocabulary sounds strange at first, but once you get the hang of the basics, everything starts to click.
Here’s my go-to guide for affiliate marketing terms explained simply.
Affiliate Marketing Terms Explained
👉🏻 Affiliate
That’s you. You share a link, product, or service from someone else, and if someone makes a purchase through your link, you earn a commission.
Think of it as recommending your favorite product to a friend and getting a small “thank-you” bonus when they try it too.
👉🏻 Merchant (or Advertiser)
The company that owns the product or service. If you promote a brand’s offers through your content, you’re the affiliate; they’re the merchant.
👉🏻 Commission
Your reward. It’s what you earn when someone purchases through your affiliate link. It’s a thank-you for connecting a buyer and a product.
👉🏻 Affiliate Link
A unique web link that the merchant gives you, so clicks and purchases can be tracked back to you. It ensures you get proper credit for every sale.
👉🏻 Cookie
Not the edible kind. In affiliate marketing, a cookie is a small tracking file that remembers who referred a visitor to a website. It helps make sure your referral still counts even if the visitor doesn’t buy immediately.
👉🏻 Cookie Duration (or Cookie Life)
This is how long your referral is remembered after someone clicks your affiliate link, usually 30 to 90 days. If a purchase happens within that time, you still earn your commission.
👉🏻 Niche
Your main topic or focus area is the space where your content lives. Staying consistent within a niche helps you attract and serve the right audience.
If you’re still figuring that out, see Niche & Brand for guidance.
👉🏻 Conversion
A “conversion” happens whenever a visitor clicks your affiliate link and completes a desired action, such as making a purchase or signing up for something. It’s that satisfying “it worked!” moment.
👉🏻 Traffic
The number of people visiting your site, reading your posts, or clicking your links. More traffic usually means more chances for conversions.
👉🏻 SEO (Search Engine Optimization)
Making your website easier to find on Google and other search engines. Our traffic section has step-by-step tips for beginners.
👉🏻 CTR (Click-Through Rate)
The percentage of people who click your affiliate link after seeing it in your post or email. If 100 people see it and 5 click, your CTR is 5%. It’s a way to measure how engaging your content is.
👉🏻 Payout Threshold
The minimum amount you must earn before a company sends you your commission. Some set it at $10, others $100 or more.
👉🏻 Disclosure
Always let readers know you may earn a commission if they click your links. Being transparent builds trust and is legally required in most countries.
You can see how I phrase it at the top of my Wealthy Affiliate Review.
Making These Terms Make Sense
Let’s bring it into context with quick, real-world scenarios:
Example 1:
You write a blog post recommending a laptop stand. Someone reads your review, clicks your affiliate link, and buys it a week later. Because the cookie saved their visit, you earn a commission.
Example 2:
You share a productivity tool on Pinterest. Two hundred people see your pin (traffic), ten click the link (CTR), and a few sign up for a trial (conversion). Once your total earnings reach the payout threshold, you get paid.
Example 3:
You run a website about affordable travel. When visitors book hotels through your affiliate link, the tracking system attributes those purchases to you. That’s how affiliates get rewarded.
Getting Started with Confidence
Affiliate marketing can look complex from the outside, but once you understand the language, it’s just a set of simple steps.
Here’s a quick path to start confidently:
1. Pick a Niche You Actually Enjoy.
Choose something you can talk about naturally and consistently. For inspiration, check Affiliate Marketing 101: A Beginner’s Guide.
2. Find Good Affiliate Programs.
Start with brands or services you already use and trust. Amazon Associates and digital-tool platforms are great starting points.
3. Write Honest Reviews.
People value real experience over perfection. Your authenticity is your best marketing.
4. Add Links Naturally.
Use affiliate links where they genuinely fit the conversation. And always include a brief disclosure note.
5. Focus on SEO Basics.
A little structure goes a long way. Learn how in Setting Realistic Goals for Your Affiliate Marketing Journey.
6. Check Your Stats, But Don’t Obsess.
Analytics help you see what works best, but remember: steady effort beats constant tweaking.
Common Questions
Is affiliate marketing really worth it?
Yes, as long as you talk about products or tools you genuinely recommend. It’s one of the simplest ways to earn income from content you already enjoy creating.
Can I promote things I haven’t tried?
You can, but it’s better to share products you know or trust through reputable reviews. Transparency builds credibility.

Most affiliate programs are free. You’ll only need a place to share your content, such as a blog or website. If you’re ready to build one, start free with Wealthy Affiliate.
