The 25 Most Expensive Keywords in AdWords – 2017 Edition!

Way, way back in 2011, when the world was young and fidget spinners weren’t yet a thing, there was lore floating around in the search marketing world that “mesothelioma” was the most expensive keyword to bid on in Google AdWords, costing upwards of $100 per click. But was it true?

I had a little idea: What if we used data from our Free Keyword Tool to determine which keywords had the highest costs per click (or CPC’s) in Google AdWords, driving up online advertising costs?
