Trust badges: which ones reassure buyers at the pay button, and which ones get a supplement brand in trouble

A trust badge has to answer two questions at the moment of paying: is my card safe here, and what happens if this doesn't work? Here's what Baymard's seal research found, where badges belong on a VSL funnel, which ones mislead, starting with anything that implies FDA approval, and how to test one honestly.

Trust badges are the seals, card marks and guarantee or certification badges that tell a buyer at checkout the card is safe and the purchase is protected. Shoppers judge a checkout's safety by how it looks, Baymard found, though its studies measure trust, not sales. Show a badge only if its claim is true: nothing implying FDA approval, no certification you don't hold, no guarantee you won't honor.

A badge can't rescue a page nobody believes. By the time a buyer reaches the card fields, the VSL has made its case, and the badges only settle the last doubts, provided every word on them holds up.

Two questions every trust badge answers

At the pay button a buyer is weighing two risks. One is the card: will these details be safe here? The other is the product: what if it doesn't work for me? Security seals and payment marks speak to the first, a guarantee to the second, and certification marks and review badges vouch for the product itself. Each kind makes a claim, and each claim has a condition it must meet:

Six kinds of trust badge and what each one claims

Security and site seals

Claim that a security company has checked the site or its connection.

Show one only while the service is active and covers this checkout
Baymard suggests placing site seals close to the card fields

It says nothing about the product.

Card and wallet marks

Say which cards and wallets you accept. Nothing more.

Visa’s September 2025 brand standards require online merchants that accept Visa to display the Visa Brand Mark, using Visa-provided artwork
A Visa Secure badge belongs only on a checkout that runs Visa Secure, and Visa says it must not imply endorsement

For other networks, check their own brand rules.

Money-back guarantee badges

Promise a refund if the buyer isn’t satisfied.

“Money back” or “satisfaction guarantee” only if you refund the full price on request
Any condition, such as unopened bottles or a return fee, stated beside the badge

Use the same words in the video, on the badge, at checkout and in the confirmation email.

Certification marks such as USP or NSF

Claim that an independent body tested this exact product to its standard.

Only for products the certifier lists
A certified facility or ingredient doesn’t make the finished product certified
Link the certifier’s own listing

NSF says only products that meet every requirement earn its mark.

Review-platform badges

Claim that other buyers rate the product, through a review service.

Only as honest as the reviews behind it
A review site you own or control can’t be presented as independent

“As seen in” logos

Claim that the outlets shown covered the product.

Only for coverage that really happened, ideally linked
Coverage isn’t a recommendation, so don’t word it as one

A badge borrows trust from whoever stands behind it: a security company, a card network, a certifier or your own refund policy. If that party wouldn't vouch for the claim, the badge shouldn't make it.

Do trust badges work? What Baymard's seal research found

Baymard Institute's research on checkout security starts from perception. Every field on an HTTPS page is equally encrypted, yet shoppers see some parts of a page as safer than others (Baymard). In its 2025 survey of 1,026 US online shoppers, 19% had abandoned a checkout in the past three months because they didn't trust the site with their credit card information.

Baymard has also asked which seals reassure most. In a January 2013 survey of US respondents, run through Google Consumer Surveys, it asked which badge gave the best sense of trust when paying online. Of 2,510 responses, 1,286 picked a seal and 49% chose "Don't know or no preference" (Baymard). Norton came first:

Which seal gives the best sense of trust when paying online?

Share of the votes, US respondents, January 2013

Norton~36%

McAfee~23%

TRUSTe~13%

BBB Accredited~13%

Baymard Institute, Google Consumer Surveys, January 9–11, 2013: 2,510 responses, 1,286 of them for a seal. It measures perceived trust, not conversion, and seal names and owners may have changed since.Source: Which Site Seal do People Trust the Most? — Baymard Institute (January 22, 2013)

Baymard asked the question six more times between 2015 and 2023, and its article gives no percentages for those runs, only the pattern: Norton's SSL seal "dominates" in the 2023 study, seals from well-known consumer brands such as Norton and Google perform very well, and a homemade seal did significantly better than SSL seals from established vendors, Norton excepted.

Those results describe how safe a checkout feels, not what it sells. Almost half of the 2013 respondents didn't know or had no preference, and a homemade seal, which nobody audits, beat most security vendors' seals in later runs. No published figure we could verify ties a badge to conversion, so be wary of any "badges lift sales by X%" claim that shows no source or sample.

Where trust badges go on a VSL funnel

Put each badge where its question comes up:

At the pitch, beside the price. The product question starts when the price appears, so the guarantee belongs next to the offer. In RevvyScales, the guarantee block holds the guarantee's text and up to three badge images and, like the offers, can stay hidden until the pitch, so it appears with the price (theme editor).
Where the buyer picks how to pay. Marks for the cards and wallets you accept, nothing more. Visa's September 2025 ecommerce brand standards say all online merchants that accept Visa must display the Visa Brand Mark on their websites and apps, using Visa-provided artwork (Visa).
Inside the card area. Baymard suggests setting the card fields apart with a border or background used only for them, placing one or two icons inside that area and keeping site seals close to the card fields (Baymard). One or two, not a wall of logos.
Under the pay button. One line with the guarantee in the same words as the video and the offer, so the promise the buyer heard is the one they pay under.
After the order. The guarantee terms again in the confirmation email.

The VSL landing page guide shows where the guarantee sits among the page's other blocks.

Badges that get supplement brands in trouble

Four kinds of badge make claims a supplement brand has to be able to prove. What follows summarizes the regulators' and certifiers' own statements; it isn't legal advice.

"FDA approved", "FDA registered" and the FDA logo

FDA doesn't approve dietary supplements. Its consumer Q&A says that under DSHEA it "does not have the authority to approve dietary supplements before they are marketed" (FDA), and its May 2026 consumer update lists supplements among the products it doesn't approve (FDA). An "FDA approved" badge on a supplement is false in FDA's own words.

"FDA registered" is the subtler version. Facilities that make or hold supplements for US consumers must register with FDA, but FDA's guide for small businesses says a registration number "does NOT convey FDA approval or endorsement of the facility or its products" (FDA). FDA issues no certificate of registration and recognizes none from a private business, charges no fee to register, and isn't affiliated with the companies that sell registration services (FDA). A "certificate of FDA registration" shown as a badge is not an FDA document. FDA's own explainer has chapters on both points, supplements and facilities:

10 Facts about What FDA Does and Does Not Approve #FDAFacts (1-10)U.S. Food and Drug Administration · Jan 25, 2024FDA’s own explainer on what it does and doesn’t approve. Its chapters include dietary supplements (0:34) and facilities (1:35).

The name is off limits as well as the logo. FDA's name and logo policy says its marks, the "FDA" name included, must not be used to indicate or imply endorsement by FDA or in connection with a third-party product, and that unauthorized use may violate federal law (FDA). That leaves no safe way to turn registration into a badge, and little reason to put it in the copy: every facility making supplements for US consumers must register, so it tells a buyer nothing about your product. If manufacturing quality is part of the pitch, point to evidence about the product itself, such as a certifier's listing, and have counsel check any line that names FDA.

A certification mark the product doesn't hold

USP's Verified Mark and NSF's product certification are earned product by product. USP says manufacturers submit products voluntarily, and those that meet its testing and auditing criteria "can display" the Verified Mark (USP). NSF says "only products that meet every requirement earn the NSF certification mark" (NSF), and its public notices count misleading "statements that imply products and services are certified or registered when they are not" as a violation (NSF).

Two easy mistakes: a GMP certificate for the factory, such as NSF/ANSI 455, certifies the facility rather than the product, and a certified ingredient doesn't make the finished product certified. Show a mark only on the exact product the certifier lists, and link the listing; the certificate of analysis post explains what each document proves.

The FTC treats seals as claims too. Under its Endorsement Guides, the name or seal of an organization can be an endorsement (16 CFR 255.0(b)), and its Green Guides, written for environmental claims, state that it's deceptive to misrepresent that a product has been certified by an independent third party (16 CFR 260.6).

A guarantee badge that promises more than the terms

The FTC's guides on guarantees say "Satisfaction Guarantee", "Money Back Guarantee" and similar terms should be used only if the seller refunds the full purchase price at the buyer's request, that material limitations should be disclosed, and that a guarantee should be advertised only if it's performed promptly and fully (16 CFR 239). A "100% money back" badge over terms that keep the shipping or require unopened bottles needs those conditions beside it. The money-back guarantee post covers the terms and their length.

Review badges, press logos and origin claims

A review badge is only as honest as the reviews behind it. The FTC's Consumer Reviews and Testimonials Rule, in force since October 21, 2024, bars presenting a review site or organization you control as independent (16 CFR 465.6); the Endorsement Guides post covers reviews and seals in more depth. An "as seen in" strip claims coverage, so show only outlets that really covered the product, and don't word it as a recommendation. A Made in USA badge falls under the FTC's Made in USA Labeling Rule, which covers a Made in USA seal or mark on product labels and in mail-order catalogs and promotional materials, websites and email included (Made in USA claims).

Side by side, the honest version of each badge and the version that gets brands in trouble:

When the seal company was the problem: FTC v. TRUSTe

A seal is a claim that someone performed checks, and in 2014 the FTC alleged that one seal company hadn't. On November 17, 2014, it announced that TRUSTe would settle charges that it deceived consumers through its privacy seal program (FTC). The FTC alleged that TRUSTe's website said seal holders were recertified every year, yet it failed to recertify them in over 1,000 instances between 2006 and 2013. It also alleged that TRUSTe misrepresented itself as a non-profit: before converting to a for-profit corporation in 2008, it gave clients model privacy-policy language calling it one, and afterwards didn't require them to update it.

TRUSTe agreed to pay $200,000, which the order calls disgorgement, under an agreement that isn't an admission (consent agreement), and the FTC approved the final order on March 18, 2015 (FTC).

The FTC acted against the seal company, not the shops that displayed its seal. The lesson still lands on the shops: TRUSTe was one of the top four seals in Baymard's 2013 survey above, a seal shoppers trusted while, by the FTC's account, its recertifications were being skipped. A seal's fame says nothing about whether its checks are current, so prefer seals a buyer can verify, and take down any you no longer pay for or qualify for.

How to test a trust badge honestly

The honest test compares the page with the badge against the page without it, on the same days, with the sample size fixed before you start. The catch is traffic: the smaller the effect you want to detect, the more visitors you need, and a badge is a small change.

Say your VSL page turns 2.5% of visitors into buyers and you'd want to detect a lift of a tenth, to 2.75%, with 2,000 visitors a day split between two versions:

Calculator

A/B test sample size calculator

How many visitors each version needs before a difference in conversion rate means something.

Current conversion rateSmallest lift worth finding (relative)Visitors a day, all versions togetherVersions, the control included

Visitors per version64,199

Visitors in all: 128,398
Days at your traffic: 64.2
Orders per version at the current rate: 1,605

95% confidence and 80% power, the usual defaults for comparing two conversion rates. Fix the sample before you start and read the result when it is reached: stopping the moment one version pulls ahead finds winners that aren’t there. With more than two versions, each is compared with the control and needs this many visitors.

That's 64,199 visitors per version and about 64 days, for a change that takes minutes to make. At the checkout the numbers get harsher: with the 1,250 checkouts a month and 40% completion from our checkout abandonment example, detecting a 5% relative lift takes 9,493 started checkouts per version, well over a year of traffic.

In RevvyScales, the clean way to run the VSL-page test is two versions of the VSL in one folder, identical except for the guarantee badge, with traffic split between them and each visitor kept on one version (folders and A/B testing). Without the traffic, skip the test and decide on the evidence: show the badges whose claims are true, place them where Baymard suggests, and spend your testing traffic on bigger changes, such as the offer or the price.

A trust badge check before launch

Frequently asked questions

What is a trust badge on a website?

A trust badge is a seal, logo or icon that vouches for something at the moment of buying: a security seal for the connection, card marks for the payment methods accepted, a guarantee badge for the refund promise, or a certification mark for the product. Each one is a claim about someone else's checks or your own promise, so it belongs on the page only while that claim is true.

Can a supplement say it is made in an FDA-registered facility?

Not as a badge, and think twice about the line itself. Every facility that makes supplements for US consumers must register with FDA, and FDA says a registration number doesn't convey approval or endorsement, so the claim tells buyers nothing about the product. FDA's name policy also bars using its name in connection with a third-party product or to imply endorsement. Point to evidence about the product instead, such as a certifier's listing, and have counsel check any wording that names FDA.

Do I need to disclose that I paid for a certification?

Not for a normal evaluation fee. The FTC's Endorsement Guides give the example of a company that paid a reasonable fee to have its product evaluated for a seal, and say consumers expect marketers to pay for certification, so the fee needs no disclosure. That example assumes a real evaluation. A seal bought without one, or from a site you control, is a different matter.

Can I make my own trust badge?

You can design a badge for your own guarantee or delivery promise, and in Baymard's later surveys a homemade seal did significantly better than SSL seals from established vendors, Norton excepted. What it can't do is imitate a certification, a regulator or a security company, or promise checks nobody performs. A homemade badge should state your own promise, in your own brand, and nothing more.

Do I have to show card logos at checkout?

Visa's ecommerce brand standards from September 2025 say all online merchants that accept Visa must display the Visa Brand Mark on their websites and apps, using Visa-provided artwork. For other networks, check their own brand rules. A card mark says only that you accept the card; it isn't a seal of approval for your store or your product.

Does a Visa Secure badge show that my store is safe?

No. Visa's September 2025 standards make the badge optional for participating merchants, and say it must not be used to imply endorsement of any product, service or merchant, or as an acceptance mark. Show it only if your checkout really runs Visa Secure, Visa's 3D Secure program, and never present it as a seal of approval for the store or the product.
