WordStream, a venture capital-backed provider of hosted software that automates most of the manual work involved with creating and optimizing both paid and natural search engine marketing campaigns, has done some research to discover which keyword categories fetch the highest costs per click (CPC) in Google’s AdWords solution.
And of course, they made an infographic based on the results of their research (embedded below).
WordStream compiled data from its own, vast keyword database and the Google Keyword Tool to determine the top 10,000 most expensive English-language keywords over a 90-day period.
Subsequently, the list was organized into categories by theme. The largest keyword categories were then 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.
The top twenty keyword categories that demanded the highest costs per click are:
1. Insurance (example keyword: “auto insurance price quotes”)
2. Loans (example keyword: “consolidate graduate student loans”)
3. Mortgage (example keyword: “refinanced second mortgages”)
4. Attorney (example keyword: “personal injury attorney”)
5. Credit (example keyword: “home equity line of credit”)
11. Conference Call
20. Cord Blood
Unsurprisingly, the list of most expensive keyword categories is clearly a result from people who, en masse, turn to the Web in search for help, whether it’s for financial, educational, professional services or medical aid. WordStream concludes that the keyword categories with the highest volumes and costs represent industries with very high lifetime customer value: in other words, companies that can afford to pay a lot to acquire a new customer because of the nature of their business.
But I would have personally never imagined that ‘insurance’ would be netting Google up to almost $55 per click. Think about that for a minute.
