Insurance-related keywords result in 24 percent of Google's AdWords revenue, more than any other search term, according to a WordStream study. Search terms using the word “claim” came in at No. 10.

The study examined which keywords demand the highest costs per click (CPC) and are most competitive in terms of high search volume. WordStream used its own keyword database and the Google Keyword Tool to come up with the top 10,000 most expensive English-language keywords over a 90-day period.

Examples of keywords in the insurance category include “buy car insurance online” and “auto insurance price quotes.” The highest CPC generates $54.91.

Coming in behind insurance search words, “loans” and “mortgage” keyword searches contribute 12.8 percent and 9 percent of revenue, respectively. Loans command as much as a $44.28 CPC and mortgages generate as high as $47.12 CPC. WordStream elected to separate these two search words, although it could be argued that they are a single category.

The remaining seven categories, in order of percentage: attorney, credit, lawyer, donate, degree, hosting and claim.
