PPC Web Spy - To use this tool, you must be using the Mozilla Firefox web browser (PC or Mac). PPC Web Spy is an extension that you install in Firefox. Basically, you type in a search term in Google and it shows you the organic search results and the paid results (like normal). But, this tool tells you two more things: which keywords the advertiser is bidding on and the actual URL of the landing page that their Google ad goes to. You can just click the Google ad to get to the landing page, but then it charges the advertiser and this is unethical if your only intention is to study their landing page.
I don't use this tool for keyword research. I just use it to study competitors' landing pages. You can sign up for a free account which shows the landing page URLs or you can get the paid version which also tells you which keywords the advertisers are bidding on.
