The Ad Library provides advertising transparency by offering a comprehensive, searchable collection of all ads currently running from across Facebook Products. Anyone can explore the Library, with or without a Facebook account.
Note that this only shows ads that are "related to politics or issues of importance" if you search by keyword (like a business or product name), and the pages search seems to be limited - I can't find my own company's page listed, yet we spend millions on FB/IG ads each year. Some competitors pages appear, but others don't.
Still seems like a nice way to spy on your competition, if you can find them.
Edit: looks like you can just put in a page ID in the URL of the search results to show ones for pages that don't appear in the list (you can get the page ID by copying the first number from the profile picture URL from the page)
Edit: I made a reddit post with detailed instructions for getting the ads for any page: https://www.reddit.com/r/Entrepr...
@mzuvella It appears to be the same info but in a bit better interface, and from my experience, the "ads and info" thing didn't appear reliably on all pages - at least now there is a way to get info for any page
