How to know who is running ads on specific keywords?

I saw that Spyfu shows websites that are running ads for specific keywords. But the data seems to be somewhat stale & incomplete. Are there any better tools?

Been down that rabbit hole myself. Spyfu's decent, but I've found SEMrush and Ahrefs to be more comprehensive. Their ad history feature gives a solid look at who's bidding on what. Also, don't sleep on AdPlexity – it's a bit more on the pricier side but offers real-time data, especially for different geo-locations.

You can use various keyword research tools to find out who is running ads on specific keywords. This information is usually available in the form of detailed reports that give you insights into which companies are bidding on certain keywords and how much they are spending.
