Online stores that started advertising on Facebook this week (week of October 26, 2026)

How we measure

A store is listed when its first ad in the AdLibrarySpy index started in the week (start date as reported by Meta), it launched 3 or more new ads, and Meta's running-ads count for the store, which the index reads, had been checked before the week and never showed it running an ad. That last check keeps out stores the index simply had not crawled before. A list needs 20 such stores (10 in a niche).

Every number is a count of Meta ads in the AdLibrarySpy index (the ads of the online stores it tracks), not a census of all of Meta. A ranking with too little data behind it is not published.
