Affiliate marketing is simple to explain: you recommend a product, include a special tracking link, and if a reader buys through it, the company pays you a commission. It is also one of the most over-hyped topics on the internet. Professor Press is here to give you the honest version, minus the rented sports cars and screenshots of mystery income.
Done well, affiliate marketing is a way to earn from content you would write anyway, by pointing readers to tools that genuinely help them. Done badly, it erodes trust fast. Let’s do it well.
How Affiliate Marketing Works
- Join a program — sign up directly with a company or through an affiliate network such as Amazon Associates, Impact, CJ, ShareASale, or Awin.
- Get your links — each program gives you unique tracking links for products.
- Create helpful content — include those links where they naturally help readers.
- Earn commissions — when a reader completes a qualifying action (usually a purchase or sign-up) within the program’s tracking window, you earn a commission according to that program’s terms.
Every program has its own rules about commissions, cookie windows, payment thresholds, and where you can promote. Read the terms before you join. Our affiliate programs directory is a starting point for finding options related to WordPress.
Heads up: Results vary enormously, and many affiliate sites earn little or nothing, especially early on. Treat affiliate income as something you build slowly on top of genuinely useful content, not a guaranteed paycheck.
Choose Products You Actually Use
The best affiliate recommendations come from real experience. Readers can tell the difference between “I’ve used this for my own site, and here is what I liked and didn’t” and a rewritten product page.
- Recommend what you know. Start with the hosting, themes, plugins, and tools you already rely on.
- Match your audience. A beginner audience needs beginner-friendly tools, not enterprise software.
- Check the company’s reputation. Support quality, refund policies, and reviews matter because your name is attached to the recommendation.
- Be willing to say no. If a product is not good, do not promote it, no matter the commission.
Professor’s note: Your readers’ trust is your real asset. One bad recommendation can undo months of goodwill.
Disclosure and Link Rules
Disclose clearly
In the United States, the FTC’s Endorsement Guides expect you to disclose material connections, including affiliate relationships, clearly and conspicuously. Other countries have similar rules. In practice:
- Place a short disclosure near the top of the post, before the first affiliate link, not buried in the footer.
- Use plain language, for example: “Some links in this post are affiliate links. If you buy through them, I may earn a commission at no extra cost to you.”
- Also add a full disclosure page and link to it from your footer.
- Some programs, like Amazon Associates, require specific disclosure wording. Follow each program’s rules.
Mark links with rel=”sponsored”
Google asks that paid and affiliate links be qualified with rel=”sponsored” (using rel=”nofollow” is also acceptable). In the block editor, you can edit link attributes directly in the code editor, and link-management plugins such as Pretty Links or ThirstyAffiliates can add the attribute automatically and help you organize links.
Tip: Use a link-management plugin from the start. If a program changes its URLs or you switch programs, you update the link once instead of editing dozens of posts.
Content Types That Work
Honest reviews
Share how you used the product, who it suits, who should skip it, and real pros and cons. Screenshots of your own setup add credibility.
Comparisons
“Plugin A vs Plugin B” posts help readers decide. Be fair, use consistent criteria, and state which you prefer and why.
Tutorials
Step-by-step guides (“How to set up a membership site”) naturally mention the tools involved. Tutorials are often the most helpful kind of affiliate content because the reader learns something even if they never buy.
Resource pages
A curated page of the tools you use, with short honest notes on each, is useful to readers and easy to maintain. See our own resources page for an example.
Building an Affiliate Site on WordPress
- Start with a clear niche so your recommendations are focused.
- Nail the basics of SEO so people can find your content. Our blog marketing hub covers this in depth.
- Build an email list so you are not dependent on search traffic alone.

Common Beginner Mistakes
- Promoting dozens of products you have never tried.
- Stuffing every paragraph with links.
- Hiding or skipping disclosures.
- Promising readers results a product cannot guarantee.
- Expecting quick income and quitting before the content has time to grow.
