I was wondering if there's a way to spy on competitor's ads (like be able to know things about their campaigns, such as who are they targeting, their budget, etc.). I've googled around and I don't seem to find a good way to do it. Thanks!
Facebook recently made it super transparent. You just need to go to your competitors' page and look at the tab on the left. You will see "Info & Ads". Inside you'll see the active ads, the one that are running right now.
