The Ad Library is the counterpart to dark posting. An ad may never appear on a page, but it does appear here. Meta’s library lets anyone search ads that are currently running across its apps by advertiser name or keyword and see the creative, the start date and the platforms it runs on (Meta; Facebook Help).
For commission UGC it is a research tool in both directions. A brand can see which creator videos a competitor is running and for how long, which is a rough signal of what is working. A creator can see whether a brand runs creator-led ads at all, and whether those ads show the creator’s handle, which tells them whether partnership ads and ad spend share are on the table.
Example. A creator is offered a share of ad spend by a skincare brand. Before saying yes, they search the brand in the Ad Library and find 30 active ads, 22 of them creator videos, several running for more than 60 days. The brand scales creator content and keeps winners live for months, which makes a share of spend worth more than a flat usage fee. Example.
When brands use it. The pain this answers: “We paid $300 a video and nine out of ten never beat our control.” Brands check competitors’ creative, look up how long rivals’ creator ads have been running, and pull inspiration for briefs. Running ads that have been live a long time are usually the ones that pay.
The creator’s view. Search any brand before a deal. If its library shows creator-fronted ads running for months, ask for a share of spend or a longer usage fee. If it shows nothing, a per-video fee is the safer deal.
On HourlyUGC. A brand that runs creator-fronted ads can launch Meta Partnership Ads with the creators’ videos from inside HourlyUGC and pay a share of the spend, 1 to 30 %.
