Short answer: a logos ad persuades with a fact the viewer can check, such as a number per serving, a price, a spec or a side-by-side comparison. Huel's "400 calories, high protein, high fiber and it takes 60 seconds to make" is a logos ad. So is Warby Parker's "Buy one Rx pair, get 20% off additional pairs."
Most ads that try to sell on facts either promise "premium quality" with nothing to check, or cram eight numbers into one picture that nobody reads. This post shows 10 logos examples in ads, sorted by the kind of proof each one uses. Four come from Meta's public Ad Library, pulled in October 2026, and six are ads Selzee made for brands. The Ad Library does not show results, so we show the ads as patterns, with the date each one started running. The same list applies if you searched for logos advertisement examples or examples of logos in advertising.
What is logos in advertising?
Logos is persuasion through proof: the ad shows, or seems to show, that its claim is true. The Stanford Encyclopedia of Philosophy entry on Aristotle's Rhetoric (revised 2022) puts the reason it works in one line: "we are most easily persuaded when we think that something has been demonstrated." In an ad, the demonstration is short. It is a number, a price or a picture of two products side by side.
The same entry names two forms of rhetorical proof: a deduction built from what the audience already accepts, and a single example that stands for a similar case. Both show up on Meta every day:
| Form of proof | How it works | In an ad |
|---|---|---|
| Deduction from what the viewer already accepts | "You want protein at breakfast. This has 40g per meal." | Huel Trial Box |
| One example for a similar case | "Here is your old wallet. Here is ours." | Ridge vs old wallet |
What does a logos ad need that a pathos ad does not?
A logos ad needs a claim that someone could prove false. "Feels amazing" cannot be wrong, so it proves nothing. "Heat-safe up to 900°F" can be wrong, and that is why the viewer believes it. We covered the feeling side in our pathos ad examples, and credibility in ethos ad examples. This post stays with proof.

Add as preferred sourceWhich logos ad examples are worth copying?
The logos ad examples worth copying use one of six kinds of proof. Here they are, with the ad that shows each one:
| Kind of proof | What the viewer checks | Example line | Ad |
|---|---|---|---|
| Number per unit | Does it beat what I eat or use now? | "40g protein per meal" | Huel |
| Time or effort | Will it fit my morning? | "takes 60 seconds to make" | Huel |
| Offer math | How much do I save? | "get 20% off additional pairs" | Warby Parker |
| Spec callout | Will it survive how I use it? | "Heat-safe up to 900°F" | HexClad |
| Comparison | Is it better than what I have? | "Slim" vs "Bulky" | Ridge |
| Guarantee | What if it fails? | "Lifetime warranty" | HexClad |
Numbers per serving or per meal
400 calories in 60 seconds (Huel). The Huel ad at the top of this post, running since October 15, 2026, packs four facts into one text block over a glass of shake: 400 calories, high protein, high fiber and 60 seconds to make. The opener, "this breakfast hack feels illegal", is a joke. The numbers do the selling. The offer at the end, "$40 of freebies", has an asterisk that limits it to new subscribing customers.
The Trial Box (Huel). A second Huel ad, running since October 16, 2026, puts three numbers in a row under the headline: "16 meals | 40g protein per meal | 8 flavours". The body copy adds price math: "Under $3 per meal." A unit number turns a box price into a breakfast price, the comparison the buyer makes anyway.
17g protein per serving (Khloud). Selzee made the Khloud ad in the collage above with one number as the whole headline. A snack buyer compares protein per bag, so the ad answers that question in four words.
Price math and offer math
20% off additional pairs (Warby Parker). In this ad, live since October 6, 2026, the headline is the offer: "Buy one Rx pair, get 20% off additional pairs." The body removes the next doubt, "no promo code needed!", and the link headline adds free shipping. The fine print says "Restrictions apply".
A price list for leads (Quinn Marketing). Selzee made this ad for an agency as an iPhone note. It lists what each step of a lead is worth to a service business, "New website inquiry: $50" up to "Project completion: $500", and ends on "Quinn Marketing audit: FREE". Next to the value of one lead, the free audit looks like an easy yes.
Spec callouts and guarantees
The grill topper (HexClad). Running since August 15, 2026. Three thin lines point from the product to three facts: "Heat-safe up to 900°F", "Easy-to-clean nonstick surface" and "Lifetime warranty". The first is a spec, the second a benefit, and the third a guarantee that answers "what if it breaks?"
Running socks (SUMS). Four callouts sit around a pair of socks in this Selzee ad: anti-blister protection, cooling mesh, arch band support and anti-slip band. Each label sits next to the part of the sock it describes, so the viewer checks the claim with their eyes.
Side-by-side comparison
Ridge vs old wallet (Ridge). This Selzee ad splits the screen: a slim metal Ridge wallet on navy, a bulky leather wallet stuffed with receipts on grey. The words are two adjectives, "Slim" and "Bulky", but the photos are the proof. The viewer sees the difference before reading anything.
What makes a logos ad weak?
A weak logos ad gives no fact to check, or so many that none of them lands.
Adjectives where the number should be
The Thrive Market ad below shows where the line runs. It asks "Tired of inflated grocery prices?" over a cart of groceries. That is a problem hook: it makes the viewer feel the price pain, and the number waits on the landing page. To make the same ad work as logos, the figure has to move into the picture. If your product page has a real figure, such as an average saving per order, put it in the headline. If it has none, do not invent one.
Too many numbers at once
Count the facts on the Blueland pouch in the collage: 60 laundry loads, 3x odor removal, 100% plastic-free and 2-in-1 stain and odor. That works on a pack, where the buyer holds it. In a feed, the viewer scrolls past before reading a list. Pick the one number your buyers compare first and make it the headline, then let the others sit on the product or in the body copy.
| Number of facts in the headline | What happens | Fix |
|---|---|---|
| 0 | The viewer has nothing to check | Swap the adjective for the fact behind it |
| 1 to 3 | Each fact gets read | Keep it |
| 4 or more | The eye skips all of them | Move the extras to the body or the pack shot |
Huel gets away with four because its text block is the whole ad, and the joke in the first line pulls the eye in before the facts start. An ad with a product shot and a short headline has no such room.
How do you make a logos claim safe to run?
Have the proof on file before the ad goes live, and make it match what the whole ad suggests, including the picture. That is the US rule.
What the FTC asks for
The FTC Policy Statement Regarding Advertising Substantiation (1984) says an ad can imply more support than it states, and then "the advertiser must possess the amount and type of substantiation the ad actually communicates to consumers." How much proof is enough depends on factors the statement lists, among them the type of claim, the product, the consequences of a false claim and "the amount of substantiation experts in the field believe is reasonable." For a DTC brand, a split-screen photo like Ridge's implies a measured difference, so keep the measurement.
For health claims the bar is higher. The FTC Health Products Compliance Guidance (December 2022) asks for competent and reliable scientific evidence: tests or studies "conducted and evaluated in an objective manner by experts" and "generally accepted in the profession to yield accurate and reliable results." It also says that fine print such as "Results not typical" does not cure a deceptive claim. So a supplement or skincare ad cannot hide a weak claim behind an asterisk. An asterisk can only explain an offer, the way Huel's explains who gets the freebies.
What to keep on file before launch
| Claim in the ad | What to have on file | Example from this post |
|---|---|---|
| Nutrition number | The nutrition label or lab sheet, same serving size | 17g protein per serving |
| Time or speed | Your own timed test of the real steps | 60 seconds to make |
| Price per unit | The pack price divided by the unit count, at today's price | Under $3 per meal |
| Discount | The offer terms, and the restrictions stated in the ad | 20% off additional pairs |
| Spec | The manufacturer's spec sheet or test report | Heat-safe up to 900°F |
| Comparison | A measurement of both products, same conditions | Slim vs bulky |
| Health or "clinical" claim | Studies on the product or its dose, read by an expert | "Backed by clinical research" |
The last row needs the most care. If an ad says "backed by clinical research", the research has to back that claim for that product, at the dose or use the ad shows.
When does logos beat pathos?
Logos usually wins when the buyer is comparing options and needs a reason to pick yours. Pathos usually wins when the buyer does not feel the problem yet. Here is the starting rule we use. Test it on your own account before you trust it:
| Situation | Lead with | Why |
|---|---|---|
| The category is bought on specs (cookware, socks, tech) | Logos | Buyers already compare numbers between tabs |
| A promo or sale is running | Logos (offer math) | The discount is the news |
| Retargeting people who viewed the product | Logos | They know what it is and need the last reason |
| The buyer must switch from a habit (old wallet, bottled detergent) | Logos with a comparison | The old product is the benchmark |
| A new category the viewer has never thought about | Pathos | No one compares specs for a problem they do not feel |
Can one ad carry both?
Yes, and the Huel ad does. The joke in the opener stops the scroll, and the four facts give the reason to click. For how to write a line that does both, read how to write ad copy.
How do you test a logos headline against a pathos one?
Run two ads with the same image, audience and budget, and change only the headline. Then read click-through rate next to conversion rate, because a fact can win the click and lose the sale, or the other way round.
- Write the pair. Logos: "40g protein per meal." Pathos: a line about the morning the product fixes. Keep the offer the same in both.
- Hold everything else still. If the picture changes too, you will not know which change moved the number. Our ad creative testing guide covers the setup.
- Read both rates. A logos headline can get fewer clicks and still bring more buyers, so one rate alone can pick the wrong ad. Put each ad's impressions, clicks and conversions into the calculator below and compare the CTR and the click-to-conversion rate.

Logos examples in ads: FAQ
What is an example of logos in an ad?
Huel's ad that says its shake has "400 calories, high protein, high fiber and it takes 60 seconds to make" is logos: every part of it is a fact the viewer can check. HexClad's "Heat-safe up to 900°F" is another. Selzee makes fact-led ads like these for your products.
How do you use logos in advertising?
Put the one fact your buyers compare first into the headline: a number per serving, a price per unit, a spec or a side-by-side comparison. Keep the proof for that fact on file before the ad runs. To get ads built around your own numbers, Selzee recreates winning ads for your brand.
What is the difference between logos and pathos in ads?
Logos persuades with proof, such as a number or a comparison, and pathos persuades with a feeling, such as relief or hope. Logos tends to lead when buyers compare options, pathos when they do not feel the problem yet. To test both on your audience, Selzee makes ads for each appeal.
Are logos claims in ads regulated?
Yes. In the US the FTC expects advertisers to hold a reasonable basis for a claim before the ad runs, and health claims need competent and reliable scientific evidence. Fine print does not cure a misleading number. Selzee builds ads from your brand's own products, so you can check each number against your records.
Is a logos ad better than an emotional ad?
Neither wins everywhere. We start with logos on retargeting, sales and spec-driven categories, and with pathos on cold audiences meeting a new category. Only a test with the same image and audience tells you which wins for your brand. For new versions to test, Selzee makes new ads every day.
Before your next logos ad goes live
Read the headline and circle the fact. If there is no fact to circle, it is not a logos ad yet. If there are more than three, keep the one your buyers compare first. Then open your files and find the proof for the one that stays.
