Winning Meta ads by niche and country: how many, how long, which format
Published 13 Nov 2026. Data read ads' status and Meta's format read 2026-11-12 and 2026-11-13; figures computed 2026-11-13 05:31 UTC (each creative counted once). Source: Meta's Ad Library (EU transparency data), read by Poseidon, unless the text names another source.
As read on 12 and 13 November 2026, 16 niche and country markets in the EU have at least 30 different winning e-commerce ads from at least 5 shops. Weight loss in France is the biggest, with 210 different winners from 19 shops, and video is its most common format; in 8 of the 16 markets, the single image leads instead.
A winning ad is one still running after 21 days or more. An ad counts for a niche when its main promise (title, first sentence or landing link) names it, from shops checked by hand: the rule Poseidon checked by hand at 95%. Brands often run the same creative on many ads: each creative is counted once here. The format is Meta's own label for the ad.

"Most common format" is the format with the most winning ads in that market, and its share of the market's winners. Medians are over all the market's winners (30 or more each).
What the table shows
- Single image leads in 8 markets, video in 8. No other format leads anywhere.
- Close calls. In menopause in Spain, video (15) is one ahead of single images (14). In weight loss in the Netherlands it's 13 images against 11 videos, and in Italy 31 against 28.
- Bloating leans on video in Italy, Germany and Spain (57% to 78% of winners), on single images in France.
- Run lengths vary widely. Medians range from 50 days (bloating in Spain) to 164 (cellulite in Italy). See how long winning ads stay live for quartiles.
How this was measured
- Source: Meta's start date, status and format label for each ad, read by Poseidon on 12 and 13 November 2026; figures computed on 13 November 2026 at 03:05 UTC.
- Which ads: winners (still active, live 21 days or more) from e-commerce shops checked by hand, whose own words name the niche. Each ad counts in the country holding the largest part of Meta's breakdown for it.
- Which markets: 30 different winning ads or more, from 5 shops or more, no shop above 40% of the ads and the three biggest shops at 90% at most. Other markets are left out.
- Days live: from Meta's start date to the last day the ad was seen running, so they're a floor, not a final length.
- Correction, 13 November 05:30 UTC: three shops whose ads named the niche only in passing were removed after a second check. Bloating in Poland fell under the shop-share rule and left the page; menopause in Germany went from 87 to 84 winners, weight loss in Italy from 69 to 66.
- Update, 13 November 06:50 UTC: each creative now counts once (a brand often copies one creative to many ads), and a market needs 5 shops. Counts went down (weight loss in France 227 to 210 different ads, menopause in Germany 84 to 46): an ad now counts when its main promise names the niche, the rule checked by hand. Bloating in Spain passes and joins.
- What this can't tell you: which format sells more. A format being common among winners shows what brands keep running, not what converts.
FAQ
Which format should I use in my niche?
This page shows what the winners in each market use most, not what works best for you. The market's own page lists its biggest ads with their reach.
Why is my country or niche missing?
It has fewer than 30 winning ads from checked shops today, or a few shops make up most of them. Markets are added when they pass.
How often is this updated?
The market pages are rebuilt every night. This article is dated: the read date is at the top.
