Affiliate marketing is the most-promoted and worst-explained income path in blogging. Most of the advice you find online is written by people selling affiliate courses, which is exactly the kind of conflict of interest that tends to produce bad advice. This post is the version I’d write if I weren’t trying to sell you anything at all.
How affiliate marketing actually works
You sign up for an affiliate program, and the merchant gives you a unique tracking link. You include that link somewhere in your blog. A reader clicks it, signs up or buys something, and you get a commission for the referral.
The mechanics here are genuinely simple. The execution that actually earns money is much harder to get right.
What earns vs what doesn’t
What earns
- Posts that match high-intent searches. “Best WordPress hosting” earns more than “What is hosting,” because the reader searching that phrase is already close to buying.
- Genuine reviews of things you’ve actually used, with specific details that aren’t already sitting on the merchant’s own site.
- Comparison posts, structured as “X vs Y” with clear pros and cons laid out for each option.
- Tutorials where the affiliate product is a natural part of the workflow. The reader learns something useful, and the product mention feels earned rather than inserted.
- Resource pages with curated tools you genuinely recommend and would stand behind.
What doesn’t earn
- Generic “10 best X” posts written purely to chase affiliate commissions.
- Reviews of products the writer has never actually touched.
- Affiliate links scattered randomly through posts where they don’t really fit.
- Banner ads for affiliate programs stuffed into the sidebar.
- Pop-ups pushing unrelated affiliate offers at readers.
The pattern that emerges is consistent: readers reward genuine usefulness and punish promotional energy. Posts that try too hard to sell tend to convert worse than posts that genuinely try to help first.
Picking programs
Three things matter most when choosing where to put your effort:
1. Relevance to your audience
The best program is one your readers would buy from anyway, regardless of the affiliate angle. If you write about cooking, recommending cookware works naturally. Recommending web hosting doesn’t fit, no matter how good the commission rate looks on paper.
2. Commission structure
Commission rates vary widely across program types, and they shift more often than most guides admit:
- Physical products (Amazon Associates): roughly 1% to 20% depending on category, though Amazon cut several category rates in 2026, so it’s worth checking current rates directly rather than trusting an old screenshot.
- Digital products and courses: typically 20% to 50%. Higher rates, generally lower volume than physical goods.
- SaaS and subscriptions: typically 20% to 40%, sometimes recurring for the life of the subscription. Often the most lucrative category over time.
- Web hosting: often $50 to $200 per signup. High payouts, but heavily promoted across the internet, so audience trust matters even more here.
3. Cookie duration
How long after a reader clicks your link does a purchase still count toward your commission? Amazon’s window is notably short at 24 hours. Sixty days is fairly standard across many programs. Ninety days or longer counts as generous.
Longer cookie windows mean more of the conversions that happen days or weeks later still credit back to you.
How many programs to join
For a new blog, two to five programs is plenty to start. More than that and you can’t realistically keep up with link rot, program changes, or staying current on the products themselves.
For an established blog in a focused niche, five to fifteen programs can work, with each one covering a different product category relevant to the audience.
Don’t join fifty programs hoping for broad coverage. Most of them will earn nothing and simply clutter your workflow.
Where to put affiliate links
Roughly in order of conversion strength:
1. Inside posts where the product is genuinely the answer
“To set this up, you’ll need a tool like this. I use Tool X, which costs $79 one time.” This kind of mention is contextual and useful. The reader is already looking for the answer, and you simply provided it along the way.
2. In dedicated review or comparison posts
Posts written specifically about products carry higher commercial intent from the reader, which tends to produce higher conversion. If you want the fuller playbook for writing these without sounding like an ad, Aurora’s guide on how to write a product review that doesn’t sound paid covers that in depth.
3. On a dedicated resource page
A standalone page listing the tools you personally recommend, with affiliate links attached. Some readers actively seek this kind of page out.
4. In your About page or email signature
Subtle, persistent placements like these earn occasionally, without asking much of the reader.
Where not to put them
- Random sidebar banners with no surrounding context.
- Pop-ups for offers that have nothing to do with the page content.
- The end of every single post, regardless of whether the link actually fits.
- Old posts where the linked product no longer matches what’s being described.
Disclosure
FTC rules in the US, and similar regulations in other countries, require disclosing affiliate relationships clearly. The good news is that clear disclosure doesn’t actually hurt conversions in practice. Readers tend to respect the honesty rather than penalize it.
The standard approach includes:
- A line at the top of any post containing affiliate links: “This post contains affiliate links. If you buy through them, I earn a commission at no extra cost to you.”
- Or a clear, inline disclosure placed near each individual link.
- A global disclosure statement on your About or dedicated Disclosure page, along with the other legal basics; Aurora’s rundown of disclosure, privacy, and legal pages every blog needs covers what else belongs there.
The FTC’s own Disclosures 101 guidance is worth reading directly rather than relying on secondhand summaries, since enforcement expectations do shift over time. Don’t hide the disclosure, and don’t bury it several clicks deep. Blogs that disclose clearly tend to perform better long-term, because readers feel respected rather than managed.
The “use what you recommend” rule
The single most important rule in all of this: only recommend things you actually use or have personally verified work.
Bloggers who recommend things they haven’t touched tend to produce shallow, interchangeable reviews. Readers can usually tell the difference, and search rankings increasingly reflect it too.
Bloggers who write from real, hands-on use produce reviews that competitors genuinely can’t match. The small details, what surprised them, what frustrated them, what made the product click for them, are the actual moat.
The realistic income picture
A blog with 10,000 monthly visitors in a category-fit niche, with affiliate links placed in 10 to 20 high-intent posts, can realistically earn:
- $200 to $2,000 a month from Amazon-style affiliate programs.
- $500 to $5,000 a month from SaaS or course affiliates.
- $0 to $500 a month from physical-product programs outside the top-earning categories.
The variance is wide because conversion depends on several things at once:
- How well your traffic actually matches commercial intent.
- How well your post matches what readers are looking for when they land on it.
- How much readers trust your recommendations already.
- How well you’ve written and placed the link itself.
The bloggers earning $10,000 or more a month from affiliates typically have either much higher traffic or much higher conversion through a tightly focused niche. The ones earning $50 a month are usually getting one or more of these fundamentals wrong.
The traps
Chasing high-commission programs that don’t fit
Hosting programs pay well, but a fitness blog still shouldn’t be promoting web hosting just because the payout looks attractive. Audience trust is the real asset here, and it’s easy to spend down without noticing.
Outdated affiliate posts
A “best X of 2023” post still earning traffic in 2026 is usually full of dead links and discontinued products by now. Audit these posts annually, and update pricing and program details whenever you touch them, since commission structures like Amazon’s have changed materially even in the past year.
Promoting too many products in one post
A “10 best X” post with ten affiliate links tends to convert worse than a “3 best X” post with three. Too many options creates choice overload and readers often click nothing at all.
Treating affiliate marketing as the primary goal
Affiliate income works best as leveraged content, where the content itself is the real asset. Bloggers who optimize for affiliate revenue at the content’s expense tend to burn out the audience that made the revenue possible in the first place. Aurora’s broader look at blog monetization paths puts affiliate income in context alongside ads, products, and sponsorships, if you’re still deciding where to focus.
What actually holds this together
Affiliate marketing works when you recommend things you genuinely use to readers who already trust you. Start with two to five relevant programs, put links in contextual places where they earn their spot, disclose clearly using the FTC’s own guidance as your baseline, and audit your posts annually as programs and prices change. Treat the content as the real asset and the affiliate income as the byproduct, not the other way around. A theme built around clean, trustworthy content presentation, like Aurora, makes it easier for readers to focus on the recommendation itself rather than the ads around it. The “earn $5k a month in 30 days” pitch is selling you a course, not teaching you how any of this actually works.
