Hi,

 

 

Im looking to purchase a/the latest tools to identify what keywords competitors are bidding on, and how much they are likely to be spending on PPC.

 

Market Samurai and Spyfu used to be the industry standard. Just wondered what you guys are using these days?

 

Is there a legal way to do this?

Or these tools are just providing some "professional" estimates?

SEMRush has something that lets you check what sort of ads they are running. It's not illegal as it runs the keywords on that page and checks for the ads

is it legal way to see privacy of others.
