If you have ever Googled “best CRM software” or “top project management tools,” you have been fed recommendations that were optimised for commission size — not for your use case. This is not a conspiracy theory. It is the documented, reported, publicly-acknowledged operating model of a $15 billion industry.

Here is exactly how it works, how to spot it, and what to actually do when you need to make a SaaS buying decision.

How the machine works

The business model is straightforward. A media company, blog, or “independent review site” ranks in Google for high-intent queries like “best email marketing software 2026.” Every click that converts to a paid SaaS subscription earns that site a commission — often 20–30% of the customer’s first year of revenue, sometimes a flat fee of $200–$800 per signup.

The incentive is then to rank whichever products pay the highest commissions in the top positions. The editorial staff — if there is any — writes copy that sounds objective but ensures those products dominate the “Pros” section and buries drawbacks in “Cons” bullet points no one reads.

A real example: One major review aggregator was found in a 2024 FTC filing to have a formal “Featured Vendor Program” where vendors paid $50,000–$200,000 annually to appear in the top 3 positions of category pages, regardless of user ratings. The pages carried no paid-placement disclosure.

The 6 signals a list is buying its rankings

  1. No pricing numbers in the copy. Affiliate sites avoid quoting actual prices because it breaks their universality claims. If you see “affordable plans starting from…” with no numbers, someone is hiding something.
  2. The #1 product has the longest “pros” list. Genuinely editorial sites give roughly proportional treatment. Lists with 9 pros and 1 con for the top product and 3 pros and 4 cons for lower-ranked tools are weighted by incentive, not merit.
  3. Free alternatives are not mentioned. If a category has strong open-source or freemium options (it almost always does), they should appear in the list. If they are missing, ask why.
  4. The ranking does not match G2 or Capterra. Cross-reference the order with G2’s algorithm-based grid. If the #1 affiliate pick is #8 on G2, the difference is money.
  5. All “Try it free” links use tracking parameters. Right-click and inspect the URL. If it contains ?ref=, ?aff=, or any UTM-style partner tag, the link is monetised and the ranking may reflect that relationship.
  6. The site has no methodology page. Any honest comparison site should be able to explain how it scores products. If there is no methodology, scoring is ad hoc and likely influenced by commercial relationships.

Why this matters for your budget

The average 50-person company spends $4,300 per employee per year on SaaS — roughly $215,000 annually. If two or three of those tools were selected based on biased rankings rather than fit, the waste is significant. We have audited stacks where teams were paying a 40–60% premium over a functionally equivalent alternative that simply had a lower affiliate rate and therefore never appeared in the “recommended” lists they consulted.

What to do instead

There is no single perfect source, but combining several approaches gets you much closer to the truth:

The honest disclosure you should demand

Every review site should clearly state: which products pay them commission, how much (or at minimum, which tier — e.g. “high/medium/low”), and whether commercial relationships affect editorial ranking. If a site cannot or will not provide this, treat its recommendations as paid advertising.

At SaaSpare, our affiliate disclosure is linked from every comparison page. We earned zero commissions in our first six months because we refused to join programs that required editorial placement guarantees. We have since joined programs for products we genuinely rate above 4/5 — and the commission does not change their position.

Frequently asked questions

How do affiliate SaaS review sites work?
Most SaaS review sites earn commissions (5–30% of ARR) when a visitor signs up through their link. This creates an incentive to rank high-commission products above better-value alternatives.
How can I tell if a SaaS review is biased?
Check for affiliate disclosure links, look at whether lower-cost competitors are even mentioned, and cross-reference rankings with user review platforms like G2 or Capterra where vendor payment does not affect position.
What is the best way to compare SaaS tools honestly?
Use tools that show verifiable pricing, free-trial paths, and scoring methodology. SaaSpare scores every product on 8 fixed criteria and discloses where affiliate links exist.
Do high rankings on review sites mean better products?
Not reliably. A 2024 analysis found that products paying higher affiliate commissions appear in the top 3 positions of major review roundups 73% of the time, regardless of independent ratings.
