How to Make Money as a Digital Product Reviewer (Without a Huge Audience)

The assumption that stops most writers from trying this is that affiliate income needs a huge following. It doesn't. Someone searching "Kit vs beehiiv" or "best platform to sell a written course" has already decided to buy something in that category. They're not scrolling for entertainment, they're comparing options right before a decision. A specific, honest comparison post can convert that reader at a rate that a general audience of ten times the size never will.

You don't need 50,000 subscribers. You need content that shows up when a small number of people are actively deciding, and a couple of programmes worth linking to when they do.

Only recommend what you'd use anyway

The reviewers who make this work long-term stick to a simple filter: they write about tools and products in a niche they're already active in, and they only recommend what they'd suggest to a friend for free. The reason is practical, not just ethical. Readers can tell the difference between a review written by someone who's used the product and one written to hit a word count and drop a link. The first kind ranks and converts for years. The second kind gets ignored, and eventually gets you dropped from the programmes you're promoting.

Pick two or three categories that overlap with what you already write about: course platforms, email tools, writing software, whatever your audience is already asking you about. Depth in a narrow lane beats a wide list of things you've never actually used.

Write comparisons that answer the actual question

A listicle titled "10 Best Tools for Creators" competes with a thousand identical posts and helps nobody make a decision. The posts that convert are specific: "Substack vs Lesso for selling a written course," "the cheapest way to turn a newsletter into a paid product," "recurring vs one-time commission, which pays more." Each of those answers a question someone typed into a search bar with a decision already half-made.

A comparison post that actually helps includes:

• Who each option is genuinely better for. Not every tool is best for everyone, and saying so builds more trust than declaring a single winner.
• A real trade-off, not just a feature list. Price, learning curve, or a limitation you ran into yourself.
• Your own numbers where you have them. A screenshot of actual earnings, an actual price comparison, a real timeline of how long setup took.
• One clear next step, usually a link to try the option you're recommending.

This is also, not coincidentally, the exact content format that ranks well in search: specific, comparison-driven, and written by someone who clearly used the thing they're describing.

Disclose it properly, every time

This isn't optional, and doing it well costs you nothing in credibility. UK advertising rules (ASA/CAP) and equivalent guidance elsewhere require a clear statement of your commercial relationship any time you share a referral link, whether that's in a blog post, a newsletter, a video, or a social post. The rule that matters most: the disclosure has to come before the link, in plain language, not buried in a footer or an "about" page.

Lesso's own affiliate terms give a good template for what this should look like in practice:

"I earn a commission if you sign up through this link."

That single line, placed near the top of a post or before the link itself, satisfies the requirement and reads as exactly what it is: normal, expected, and not remotely damaging to your credibility. Readers assume you're being paid for recommendations anyway. Saying so plainly builds more trust than pretending otherwise.

Where to put the links

Three placements do most of the work:

• Inline, in the sentence making the recommendation. This is where the highest-intent clicks happen, right after you've made the case for something.
• A dedicated resources or "tools I use" page. Readers who like your work will often check this page directly, and it keeps every link in one place you can update as programmes change.
• The bottom of relevant newsletter issues. If you write about a topic and mention a tool in passing, a single line with your link at the end catches readers who were already nodding along.

Avoid stuffing links into content where the recommendation doesn't fit naturally. It reads as spam, and most programmes (Lesso's included) explicitly prohibit incentivised or misleading placement as grounds for removal from the programme.

Track what actually converts

Most referral links carry a tracking parameter for a reason: it's the only way to know which piece of content is actually earning. Keep a simple list of which posts carry which links, and check back after a few months. A two-year-old comparison post that still ranks can keep paying out long after you've stopped thinking about it, which is exactly the kind of compounding return that makes this worth doing properly the first time rather than rushing it.

Cookie windows matter here too. If a programme only credits you for 7 or 30 days after a click, a reader who bookmarks your post and comes back six weeks later won't count as your referral. Programmes with longer windows, Lesso's is 90 days, forgive slower buying decisions, which matters most for higher-consideration purchases like a course platform or a paid tool subscription.

A worked example

Say you write about tools for newsletter writers and you review course platforms as one category. You join Lesso's affiliate programme, which is free and doesn't require you to be a Lesso creator yourself. You write an honest comparison of platforms for turning a newsletter archive into a paid course, disclose the relationship clearly, and link to Lesso where it's the right fit for the reader.

Every creator who signs up through your link and later sells a course generates a commission: 50% of Lesso's net cut of that sale, for as long as their account stays active, with no cap on how many creators you refer. One creator with a steadily selling $79 course generates a little over $4 per sale for you, indefinitely. A handful of creators referred from a single well-ranking comparison post can add up to a real second income stream without you ever touching Lesso's product yourself.
