How to Evaluate a Product Before Promoting It: A 5-Gate Checklist (Refund Policy First)

How to Evaluate a Product Before Promoting It

To evaluate a product before promoting it, check five things in this order: the refund terms, whether the vendor can substantiate its claims, whether the reviews are genuine, who is behind the company, and what the affiliate terms say about reversals. If any one fails, walk away — no commission rate is worth your readers' trust.

That is the method in one paragraph; the rest of this guide is how to run each check without a law degree. The order matters. Refund terms are written down and take minutes to read, while claim support can take an afternoon, so failing fast on the cheap checks saves you the expensive ones.

If you have ever recommended something and then watched the refund requests arrive, you already know why this matters more than the payout. Recommending a product with a hostile refund policy or a promise the vendor cannot back up costs you the one asset that makes affiliate marketing work at all: readers who believe you.

The five gates, in plain terms:

• Refund terms — can a buyer get their money back, and does that reverse your commission?
• Claim support — is there real evidence behind the headline promise?
• Review integrity — are the reviews real, complete and visible?
• Vendor credibility — is there a company you can name, contact and check?
• Affiliate terms — do the program rules treat you fairly on reversals and attribution?

We publish the criteria we use ourselves on our review methodology page, so you can hold this article to the same standard you would hold us to.

Why the Refund Policy Comes Before the Commission Rate

A refund policy is not a legal footnote. It is a statement about how the seller expects to treat people after the sale, and it tells you how many of your referred sales are likely to come back out of your balance later. A generous, clearly written policy is a quality signal; a hostile one is a warning you can read in two minutes.

The four refund questions to answer

• How long is the window? Does it start at purchase or at delivery, and is it stated in writing on the checkout page as well as the program terms?
• Who processes it? Does the buyer contact the vendor directly, or is there a self-serve form? A policy that only exists as “contact support” with no stated timeframe is a red flag.
• What is excluded? Digital downloads, consumed coaching hours and subscription renewals are often excluded or pro-rated. Read the exclusions before you write a single word of praise.
• Does a refund reverse your commission? This is set by the affiliate program's terms, not by the sales page, so read it there.

The sales page, the FAQ and the affiliate program's terms should agree with each other. When they do not, the stricter version wins in practice, so plan around it.

Where your commission goes when a refund lands

Whether a refunded order claws back your commission is decided by the individual program, and the detail is often buried in a reversals clause. It also explains why an approved commission is not money in your account yet — the lifecycle from pending to paid is covered in our guide to pending, approved, reversed, paid.

Program terms change without ceremony. Note the date you read them, and re-read the reversals and refund sections before you publish anything that depends on them. For one category worked through, our SEO software affiliate programs guide compares the published terms of the main SEO tool programs.

Can the Vendor Actually Back Up Its Claims?

Most beginners skip this check, and it's the one that most often embarrasses a site later. The FTC’s Endorsement Guides’ examples require advertisers to have competent and reliable scientific evidence for the efficacy claims they make, such as hair-growth claims ^[1]. In plain language:

• Testimonials alone are not proof. A page full of happy-customer testimonials can imply results are typical, and a disclaimer may not fix that unless the vendor has substantiation ^[1].
• An expert endorsement needs serious substance. If someone is presented as an expert, they must have actually exercised that expertise—like examining or testing the product—not just read a summary ^[1].
• Run the claim-support test. Pick the single strongest promise on the sales page and ask: Is there a named study? Who funded it? How large was the sample? Does the study measure the outcome promised, or something else? Does the fine print soften it?
• If the answer to “is there a named study?” is “no, but thousands of happy customers,” that’s a testimonial, not substantiation.

If you plan to write about a product you have not used, our guide to writing an honest product review when you haven’t bought the product explains the difference between analysis and pretending.

How to Tell Real Reviews From Manufactured Ones

Fake reviews are the easiest part of your research to manipulate. The FTC’s Rule on Consumer Reviews and Testimonials (16 CFR Part 465) makes several practices unfair or deceptive ^[2]. In plain language:

• Buying positive reviews with compensation is prohibited ^[2].
• Employees posting about their own business must clearly disclose their relationship ^[2].
• Threatening or intimidating customers to remove negative reviews is prohibited ^[2].
• Presenting a company-controlled site as an independent review source is prohibited ^[2].
• “Clear and conspicuous” means easily noticeable and understandable—not a grey nine-point footer disclaimer ^[2].

What to look for on a live review page: open the two- and three-star reviews first (on a legitimate page they exist). Check whether dates cluster around a product launch or repeat the same phrases. Check whether negative reviews get a substantive reply or a legal-sounding threat. Then check who owns the review site—if the “independent review” domain is registered to the vendor, you’re reading an advert.

Google’s reviews system, updated 10 December 2025, rewards in-depth research and original analysis over thin summaries ^[3]. That’s another reason to write your own honest, specific evaluation. Our guide to “best X” lists done right shows what that looks like in practice.

Vendor Credibility: The Five-Minute Background Check

You do not need a private investigator. You need a company name, a way to contact it, and evidence that it has been around long enough to have a refund history.

• Name and address. A registered business name and a physical address in the footer or terms. No address anywhere on the site is a fail.
• Support. A support email or ticket system that is not simply a contact form promising a reply “within 24–48 hours” with no evidence anyone answers.
• Pricing honesty. The price on the sales page should match the price at checkout, including any mandatory upsell or subscription. A surprise recurring charge at checkout is a trust problem you cannot write around.
• Consistency. The refund policy on the sales page, the checkout and the program terms should say the same thing.
• Program behaviour. Has the affiliate program changed its commission structure recently? Do affiliates publicly complain about unpaid commissions? Search the program name plus “payment” and read the last year of results.

While you are in the program's dashboard, sanity-check the numbers you will be tempted by. A big advertised EPC is a network average, not a promise to you; our explanation of what EPC means in affiliate marketing walks through that. If you plan to write about how long a cookie lasts, our explanation of cookie duration and attribution windows covers what the number actually measures.

The Due-Diligence Scorecard You Can Copy

Copy this table into a document and fill one row per product. Give each row a pass or fail, plus one line of evidence and the date you checked. Working through the table gives you a written basis for the decision instead of second-guessing whether a commission was worth it.

My own scoring rule: eight passes means promote; six or seven with rows 1, 2 and 3 all passing means publish with caveats; anything else goes in the “not yet” folder and stays there until something changes.

Before you spend another dollar on a tool, run every option through this scorecard. If you want the full pre-promotion sequence—research, disclosure, publishing—in one printable list, grab the free affiliate marketing checklist below.

An Illustrative Example: Two Products, Two Outcomes

Illustrative example. The click and conversion numbers below are assumptions chosen to make the arithmetic easy to follow. They are not typical results and they are not a prediction.

Product A pays 40% on a $97 product, so each sale earns 97 × 0.40 = $38.80. Over 100 clicks you make 4 sales: 4 × 38.80 = $155.20 gross. Two buyers refund, and the program reverses those commissions: 2 × 38.80 = $77.60 reversed. Net: 155.20 − 77.60 = $77.60.

Product B pays 50% on a $49 product, so each sale earns 49 × 0.50 = $24.50. Over the same 100 clicks you make 8 sales: 8 × 24.50 = $196.00 gross. One buyer refunds: 196.00 − 24.50 = $171.50 net.

Product A has the higher price and the more impressive-sounding commission. Product B pays you more than twice as much from the same traffic. In this illustration, that gap comes from the assumed sales-per-click and refund rates — the inputs your due-diligence reading helps you estimate — rather than from the headline commission percentage alone.

The point is not that cheap products always win. It is that the refund clause and the reader's fit belong in the same calculation as the percentage, and you can only put them there if you checked them first.

Writing the Recommendation Honestly Once a Product Passes

Passing the checklist earns a product a fair hearing, not a standing ovation. What you publish still has to be accurate.

The Endorsement Guides require that a material connection between you and the seller be disclosed clearly and conspicuously; their examples treat a disclosure that is easy to miss as not clear and conspicuous ^[1]. Part 465 uses the same “easily noticeable and easily understandable” standard in its definition ^[2]. Put the disclosure where a reader meets it before the first link, not in a footer. Our FTC affiliate disclosure examples show how that reads on a blog, in email and on video.

Then be specific about your process. The Guides' examples show how endorsements can imply experience the endorser does not have — a testimonial suggesting regular use would be deceptive if the person only used the product in a demonstration ^[1]. So state what you examined: the sales page, the refund policy, the program terms, published studies, public reviews. Say what you did not examine, and why.

Three habits keep this maintainable:

• Date the post and add the last-checked date for the pricing and refund terms.
• Include the drawbacks you found in the same section as the benefits, not buried at the end.
• Re-check on a schedule — our guide to refreshing old affiliate posts lists what to re-verify first.

If you are comparing two products that both pass, structure the post so the reader can decide, not so the higher payer wins. Our comparison post template is built for that.
