Google AdWords is a dynamic, auction-based marketplace where advertisers bid on keywords to compete for top ad placement. The minimum bid per keyword is 5 cents, but this research shows that in highly competitive categories, Google can make up to $50 per click from PPC keyword bids. Despite a diversified product portfolio, advertising on Google sites accounts for the vast majority of its billions in annual revenue.
The keyword categories with the highest volumes and costs represent businesses with very high lifetime customer value – in other words, these industries can afford to pay a lot to acquire a new customer. These most expensive keywords comprise businesses such as lawsuits, mortgage applications, and server hosting. Some high-volume keyword categories have lower CPCs because advertisers have slimmer margins to expend on PPC advertising.
You can find CPC estimates for keywords using a keyword tool like Keyword Planner or our own Free Keyword Tool.

This keyword list was then organized into categories by theme, such as "Insurance." The largest keyword categories were determined by weighting the number of keywords within each category, as well as the estimated monthly search volume and average cost per click for each keyword.
