The short answer
We matched 12 fill-in-the-blank hook formulas against the opening lines of 1,752 winning Meta video ads. The most used ones are not the strongest: "If you [have X], watch this" appears 53 times and only 1.9% reach the top tier, while numbered lists ("Three signs...") reach it 13.2% of the time.
The 12 formulas, ranked by what the data says
A formula is a sentence shape you can reuse: "Watch what [X] does to [Y]". To find the ones winners actually use, we ran pattern matches over the first spoken sentence of every video ad on the Ad Radar board that has a transcript: 1,752 ads, all live on October 9, 2026, all with $50k or more in estimated spend.
| Formula | Ads | Reach top tier | Median est. spend |
|---|---|---|---|
| "This is [what / the / why]..." | 73 | 9.6% | $238K |
| "Here's what happens when..." | 55 | 7.3% | $252K |
| "If you [have X], watch this" | 53 | 1.9% | $248K |
| "[Number] signs / mistakes / rules" | 38 | 13.2% | $337K |
| "Watch what [X] does to [Y]" | 34 | 0% | $203K |
| "This is how I [result]" | 33 | 12.1% | $292K |
| "X versus Y" | 10 | 40% | $619K |
| "[Audience], ..." callout | 10 | 10% | $344K |
| "Most people think..." | 9 | 11.1% | $302K |
| "Do not buy X until / unless..." | 8 | 37.5% | $287K |
| "I'm your [body part / problem]" | 7 | 14.3% | $454K |
| "Nobody told me / nobody wants to admit" | 7 | 0% | $457K |
Across the board, about 10% of ads reach the top tier (top 10% by winner score, live 21+ days). Anything under 20 ads is a small sample. Read those rows as leads.
The pattern in the table is uncomfortable for anyone writing from a swipe file. The two most copied formulas in health and pet ads, "If you have X, watch this" and "Watch what X does to Y", are the two weakest. They still get to $50k+ in estimated spend (every ad here did), but almost none of them reach the top tier.
Formulas that hold up
1. The numbered list: "[Number] [signs / mistakes / rules] ..."
38 ads, 13.2% in the top tier, median estimated spend $337K. The number promises a finite, scannable payoff, and the noun ("mistakes", "red flags", "rules") tells the viewer what kind of payoff.
PetLab Co. (est. $520K, 110 days, top tier): "Never ignore these three hidden distress dog behaviors: paw licking, itching, and head shaking."
The PetLab line names all three items in the opener, so the viewer can self-check before the second sentence. More numbered openers are in specific-number hooks.
2. The comparison: "X versus Y"
Only 10 ads, but 4 of them are in the top tier and the median estimated spend is $619K. The viewer has usually already compared these two options in their head. The ad joins a conversation that is already happening.
So what's the better foundation, Estée Lauder Double Wear or the Luxe Color Changing Foundation?

Names a famous incumbent next to the product. Solution-aware buyers already searching for "best foundation" recognize the matchup at once.
Template: "So what's better, [known product] or [your product]?" It only works if you can name the incumbent your buyer is actually choosing against.
3. The method reveal: "This is how I [result]"
33 ads, 12.1% top tier, $292K median. The speaker shows the outcome they get and promises the method. It reads as a tip, not an ad.
Serena Williams (est. $873K, 84 days): "This is how I get up to 50 grams of protein per meal."
The number does a lot of work here too. "This is how I eat more protein" would be a weaker line.
4. The pre-purchase stop: "Do not buy X until / unless ..."
8 ads, 3 in the top tier. A small sample, but the shape is distinctive: it sounds like advice against buying, then turns into a reason to buy now or buy here.
Merachfit.us (est. $444K, 37 days, 3 variants): "Do not buy the Mirage Vibration Plate unless you're gonna buy it here and get a double discount."
This one works for product-aware buyers who already know the item. It does nothing for someone who has never heard of it.
5. The personified problem: "I'm your [body part / problem]"
7 ads with a median estimated spend of $454K. The problem speaks in first person, often in animation. It makes an invisible issue concrete and gives the ad a character in the first second.
Koprez (est. $876K, 87 days, top tier, cartoon animation): "I'm your plantar fascia, and every stretch is tearing me more."
Seven ads is too few for a rate, but the format is cheap to test and rarely seen outside health. A pet or cleaning brand could borrow it.
Formulas that are everywhere and rarely win
6. The outcome preview: "Here's what happens when ..."
55 ads, 7.3% top tier. Common in food, supplements and pet. It promises a before-and-after told over time, which is a good promise, but it is used so often that it has become filler in many scripts.
If a woman dyes her grays with box dye today, here's what happens two weeks later.
- Est. spend

The hypothetical version adds a character and a time frame. The script then walks through the salon alternative, $200 and three hours, before the product appears.
The hypothetical version ("If a [person] did X, here's what would happen") appears in only 4 ads, so we can't rate it. The Polar line shows why it reads better than the bare "here's what happens when": it has a person, an action and a date.
7. The condition gate: "If you [have X], watch this"
53 ads and only 1 in the top tier (1.9%). It is the most common opener in problem-aware health ads, and it filters correctly, but it gives the viewer no new information. They already know they have X.
If you've got a crack spreading across your windshield, you need to see this before you spend hundreds on replacement.

One of the better versions of a weak formula: it adds the cost of the alternative ("hundreds on replacement"), so the gate carries a reason to keep watching.
If you use this shape, add a stake after the condition, as Musette Beaumont does. "If you have X, watch this" alone is a filter with no hook.
8. The ingredient demo: "Watch what [X] does to [Y]"
34 ads, zero in the top tier, median $203K. Almost all of them come from a handful of pet and digestion advertisers running the same shape with a different ingredient each time.
Pup Labs (est. $359K, 248 days): "Watch what apple cider vinegar does to your dog's belly."
These ads clearly earn their keep (248 days live is not an accident), but the formula has saturated its niche. If three competitors already run "Watch what X does to Y", your version is the fourth one the viewer has seen this week.
9. The confession: "Nobody told me ..." / "Nobody wants to admit ..."
7 ads, none in the top tier, but a high median estimated spend ($457K). Small sample, so no verdict. The best one ties the confession to a sharp opinion:
Gaige Gibbs (est. $457K, 155 days): "Nobody wants to admit this, but cooking for one is a scam."
The flexible formulas
10. "This is [what / the / why] ..."
The most common shape (73 ads, 9.6%) is barely a formula. It points at something on screen. It works when the visual does the hooking, and fails when the visual is a product on a table.
11. The audience callout: "[Audience], ..."
10 ads, 10% top tier. The first word names who the ad is for.
Nobl (est. $389K, 182 days): "Overpackers, this bag's for you."
Thrive Causemetics (est. $298K, 47 days, 4 variants): "Ladies, if you have brown eyes, you need this."
Thrive runs the same line by eye color ("if you have green eyes" is a separate ad). That is a callout used as a targeting system inside the creative, which is how broad targeting expects you to work.
12. The belief flip: "Most people think ..."
9 ads, 11.1%. The opener states a common belief and sets it up to be broken.
Marlene's Pet Shop (est. $313K, 234 days): "Most people think cat scratchers exist to protect furniture, but scratching was never about furniture in the first place."
This is the formula version of the contrarian reveal, which has the highest top-tier rate of any common hook mechanism on our board. See contrarian hooks.
How to use these formulas without sounding like everyone else
- Pick formulas from the top half of the table first. Numbered lists, comparisons and method reveals have both volume and above-average top-tier rates.
- Check your niche for saturation. Search transcripts in your category for the formula's fixed words ("watch what", "if you have"). If more than a few active competitors use it, move on.
- Fill every blank with a specific. A number, a named competitor, a price, a time frame. "Here's what happens two weeks later" beats "here's what happens".
- Add a stake to any gate. "If you have X" needs a cost or a surprise after it.
- Write one body, test four formulas. Keep everything after the first sentence identical. That is the cleanest way to learn which shape works for your buyer.
- Retire a formula once it shows up in your competitors' ads. The zero in the "Watch what X does to Y" row is what saturation looks like.
The pillar list of 60 real openers groups hooks by pattern rather than by sentence shape, and AI hook generator prompts shows how to have Claude fill these templates from real winners instead of from its own defaults.
