Spot bias by looking for undisclosed financial ties, rankings with no stated method, identical praise across many tools, and buy buttons beside every verdict. The FTC says material connections should be disclosed clearly, close to the claim, and not hidden behind a click or at the end.
What counts as a material connection
The FTC describes a material connection as a personal, family, employment or financial relationship with a brand. Financial does not only mean cash. The agency says disclosure is needed if someone received anything of value for mentioning a product, and that free or discounted products should be disclosed even if the reviewer believes their evaluation is unbiased.
For a buyer, that means a free license, a paid trip, a revenue share on referrals and a speaking fee are all worth knowing about.
Signs on the page
None of these proves bias. Together they are a pattern worth noticing.
- Every product gets a glowing verdict and a button to sign up.
- A ranked list appears with no description of how items were scored.
- Weaknesses are vague ("could be more intuitive") while strengths are specific.
- The reviewer never mentions a test they ran, a version, or a date.
- The wording of the review closely matches product marketing pages.
- Links go through tracking addresses and no disclosure is nearby.
Check where the disclosure sits
The FTC guidance says disclosures should be hard to miss and placed with the endorsement message. It also says that, in videos, the disclosure should be in the video itself and not only in the description. If a video review has a sponsorship note only in a collapsed description, the guidance suggests that is not enough.
Use plain terms as a test. The FTC recommends words such as ad, advertisement or sponsored, and advises against vague tags such as collab.
Compare against other sources
Read at least three sources with different funding models: a community discussion, a reviewer who publishes method, and your own test results. Where they agree, confidence rises. Where one source differs alone, ask why.
Ask the reviewer directly
Independent reviewers usually answer questions. Ask whether any vendor supplied licenses, reviewed the draft before publication, or influenced the ranking. A clear, calm answer is a good sign. Refusal to answer is a reason to discount the piece.
What to do with biased reviews
You do not need to throw them away. A sponsored review may still list real features and real limits. Use it to build your question list. Then verify each claim with a test on your own code, as described in our guide to fair scanner tests.

Quick check
Do affiliate links make a review wrong?
Not automatically. They create an incentive, so the connection should be disclosed clearly and the claims should be checked independently.
Is a free license a conflict of interest?
The FTC says free or discounted products should be disclosed even when the reviewer thinks their evaluation is unbiased. Treat it as a connection worth knowing about.
