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!
AdFinder is a tool I use pretty regularly (along with a few others) to find all keyword (branded or otherwise) relevant posts and ads on Facebook.
Another similar hack is to use GrowthBot from HubSpot (installed on facebook messenger or Slack) and ask GB what keywords a competing company is buying in adwords.
I hope this helps!
