The Meta Ad Library is public, free, and the closest thing to a shared record of what everyone in your category is running right now. It is also read badly more often than it is read well, because most of what people want from it is not actually in there.
Here is what a listing gives you, and what it does not.
What the listing tells you
The launch date. Every listing carries the date the ad started running. On its own that is trivia. Compared against the rest of an advertiser's library it is the single most useful number on the page — see below.
Whether it is still active. Meta marks ads as active or inactive, and shows the date range for ones that have stopped. An ad still running months after it launched is the strongest public signal you can get that it is working.
How many variants exist. A listing groups ads that share the same creative into one entry and tells you how many versions are live. A lot of variants means the advertiser is testing around that idea rather than past it.
Which placements it is running on. Facebook, Instagram, Messenger, Audience Network. A creative built for one and dumped into the rest usually looks like it.
The full creative and copy. Video, image, primary text, headline, and the landing page it points at. This is the part everybody uses and it is the least interesting part, because it is the output of a decision rather than the decision.
What it does not tell you
Spend. Outside of political and issue ads, there is no budget figure. An ad running for six months might be carrying the account or might be a forgotten $5-a-day campaign nobody paused.
Performance. No impressions, no clicks, no conversions, no ROAS. Longevity is a proxy for performance and it is the only one you get.
Why. The listing is the finished artifact. It does not tell you what the advertiser was reacting to, which audience it was built for, or what it beat.
The one number worth computing
Sort an advertiser's whole library by launch date and look at what survived.
Ads that ran for a week and stopped are tests. Ads that have been running for three months are the control. The ratio between those two groups tells you how aggressively the account is testing, and the contents of the second group tells you what they have already proven — which is a far better starting point than whichever ad happened to be at the top of the page when you searched.
That is the whole method: not "what are they running", but "what did they keep".
Where to go from here
If you want the same view across every advertiser in your category rather than one at a time, that is what we built Flashfeed for — see pricing for what that looks like.
