Ethos examples in ads: 6 kinds of trust a brand borrows or earns

Short answer: ethos in an ad is the appeal to credibility. The ad gives the viewer a reason to believe the brand before it asks them to buy. In ads running on Meta today, that reason comes from one of six places: a famous partner, an expert or creator who uses the product, an award or ranking, reviews from verified buyers, years in business, or proof that the brand does what it says it values.

If you came here for a class, that first paragraph is your definition. The rest is for people who have to make an ethos ad work. Most brands have a credential. The hard part is that viewers have seen a thousand fake ones, so a credential that looks borrowed reads as a lie. Every example below comes with what makes it believable and what would make it fake, including the US rules that turn "fake" into a legal problem. The ads by HexClad, Warby Parker and Nutrafol come from Meta's public Ad Library in October 2026. The Ad Library shows no performance data, so we say when each ad started running, never how it performed.

What is ethos in advertising?

Ethos in advertising is the part of an ad that answers "why should I believe you?". Pathos answers "why should I care?" and logos answers "why is this the right choice?". We covered all three side by side, with the ASPCA ads, in pathos ad examples. This post goes one level down, into where the credibility comes from.

A brand gets ethos in two ways. It can borrow it from someone the viewer already trusts, or it can earn it with something the brand has done. Borrowed trust is faster and costs more. Earned trust is slower and cheaper to run once you have it.

How is ethos different from social proof?

Social proof is one source of ethos: other buyers vouch for you. Ethos is the wider idea. A founding year or an award is ethos without any crowd. If reviews are your main asset, our post on social proof ads covers which review to pick and how to turn it into a hook.

Which ethos examples in ads borrow trust from a person?

The fastest way to borrow trust is a person the viewer already knows. Meta has a format for this: partnership ads, which "allow you to run Facebook and Instagram ads from a creator or other partner's handle" (Meta for Developers, partnership ads, 2026). For a DTC brand, the partner's name sits in the ad's header next to yours, so the viewer sees the relationship before they read a word.

A celebrity partner: Gordon Ramsay with HexClad

HexClad's ad shows Gordon Ramsay in chef whites, holding a pan, under "Buy once. Cook for life. Save $300 off the 12-piece set." In the Ad Library the page reads "Gordon Ramsay with HexClad", a partnership ad, running since August 15, 2026. The body copy says "If you're serious about cooking, start with the right tools."

Why it is believable: a chef stands next to a pan. The fit is obvious, so nobody asks why he is there, and his face makes the durability promise ("buy once") worth taking seriously. The ad leads the collage at the top of this post.

An athlete partner: Arch Manning with Warby Parker

Warby Parker puts a pair of tortoiseshell glasses on an American football, under "Arch Manning is on Team Warby". The page is "Arch Manning with Warby Parker", running since October 1, 2026, and the copy says he "is back on Team Warby for season two". The CTA is "Shop Arch's go-to frames".

This one is weaker on fit: a quarterback does not need glasses for his job. Warby makes up for it with "season two" and "go-to frames". The ad claims only that he wears them. That is the honest version of a celebrity ad.

A creator with a long history: Spike Jonze with Warby Parker

Try on my brand

Warby Parker started this ad on the same day, with a different kind of ethos. The director Spike Jonze draws the ad himself, and the copy says "He's worn Warby Parker for over 10 years. Shop our new collaboration." The 10 years do the work. A creator who has used the product for a decade is more believable than a bigger name who started last month.

What makes a borrowed endorsement fake?

The US rules are specific. The FTC's endorsement guides, revised in 2023, say that when an ad shows the endorser uses the product, "the endorser must have been a bona fide user of it at the time the endorsement was given" (FTC Guides Concerning Endorsements, 16 CFR 255.1). A paid relationship must be "disclosed clearly and conspicuously", and that includes "the provision of free or discounted products" (16 CFR 255.5). What this means for a DTC brand: a creator who got a free sample is a paid endorser, so run the post as a partnership ad with the label, and only claim use the creator really has. If you work with creators often, our UGC creators guide covers the brief.

Ethos advertisement examples that borrow trust from a third party

A third party is anyone who is not the brand and not a paid face: a ranking, a panel of experts, or the buyers themselves. The same list applies if you searched for ethos ad examples or ethos in advertising.

An award or ranking: Nutrafol and the U.S. News badge

Nutrafol's ad, running since October 19, 2026, is a product shot: the Nutrafol Women bottle and a gold badge that reads "Best OTC Medicine & Health Products, U.S. News, Hair growth oils and serums (non-medicated), 2026-2027". The copy is short: "A whole-body approach to hair health."

The badge carries the ad. The copy says almost nothing, because a name the viewer already trusts, a category and a year do the talking. A badge is only as strong as the people who gave it, so if yours comes from a panel, a jury or a test lab, name them in the copy.

Run a badge only while it is current, and show the exact category and year it was given for. A careful viewer reads the small print on a badge before the headline.

Reviews from verified buyers

Try on my brand

Reviews are the ethos almost every brand can afford. Selzee made the ad above for Dalora, a Slovak shop, so the text is in Slovak. It shows three short quotes, each marked "Overený nákup" (verified purchase), and a bar that reads "4,9 z 5 · 168 hodnotení na Dalore": 4.9 of 5 from 168 reviews. The exact number helps. 168 reads like a count, and a round 200 would read like a guess.

The Bombees ad in the collage at the top, which Selzee also made, uses the same move with photos: three cards from "verified parent" reviewers next to the pillow. Every quote must come from a real buyer, because the FTC rule on fake reviews below applies to each one.

The FTC made fake reviews a rule violation in 2024. Its final rule bans reviews "by someone who does not exist, such as AI-generated fake reviews", undisclosed reviews by insiders, and paying for reviews "conditioned on the writing of consumer reviews expressing a particular sentiment" (FTC, final rule banning fake reviews and testimonials, August 2024). In practice, quote only reviews a real buyer wrote, and never write a "sample review" for an ad, even as a placeholder.

Which ethos ads earn trust the brand built itself?

Earned ethos needs no partner and no badge. It is something the brand did, written as a fact the viewer can check.

Heritage and years in business: Kit-Cat Klock

Try on my brand

Selzee made this Kit-Cat Klock ad as a whiteboard note: "Eyes? They roll. Tail? Wags." Then the credential, in one plain line: "One cat clock, 15.5 inches head to tail, made in the USA since 1932." The joke gets the read, and the year gets the trust. A product that has sold since 1932 has survived a lot of competitors, and the viewer does that math without help.

Values and proof of action: tentree

The tentree ad in the collage, also made by Selzee, opens on "Clothes make the man", then "But", then a man in a maroon hoodie and the line "Sasquatch Hoodie plants 10 trees." A value only becomes ethos when it has a number on it. "We care about the planet" proves nothing. "Plants 10 trees" is a promise with a count, and a buyer can ask where the trees are.

When does earned ethos backfire?

When the viewer cannot check it. A founding year must belong to your company, not to a brand you bought. A cause claim needs a page that shows who did the work and where. If your answer to "how do I know?" is "trust us", the ad has only a slogan.

How do you check an ethos ad before and after launch?

Check the claim before launch and the landing page after it. Most ethos fails at one of those two points.

After launch, judge trust where the buyer decides: on the landing page. A credential that gets the click and then disappears from the product page loses the sale there. Put the same badge, quote or partner on the page the ad links to, then check whether the landing conversion rate moves.

Change one credential at a time, or you cannot tell which one moved the rate. The fact-led side of the same test is in our logos ad examples.

How Selzee makes ethos ads

Selzee finds the ads that win in your market right now and recreates them for your brand, with your products, logo, fonts and colors. Some of those ads lead with a credential: a review count, a founding year, a research claim.

Try on my brand

Selzee made the SunPowerLED ad above. It leads with expertise: "Medical-grade PBM backed by clinical research." A line like that needs the study behind it before it runs, and only you hold the study.

Each ad comes with the angle and the insight it is built on, so you know which kind of ethos it uses before you test it. You approve the ones you want and publish them in one click. See how it works on the AI ad generation page.

What to do with this

Pick the one credential you already have and a buyer can check, put it in the headline of one ad, and put the same credential on the page that ad links to. Then test it against the ad you run today. The next credential can wait until the first one has a result.
