WordStream has put together a rather interesting infographic showing where Google makes its money. "We did some research on what are the most expensive keyword categories in the world to figure out where (specifically) Google makes their billions in ad revenues," WordStream Founder Larry Kim tells WebProNews.
Below is what they came up with.
They managed to turn the infographic into an ad, but the data is still interesting.
To come up with this, WordStream compiled data from its own trillion-keyword database along with the Google Keyword Tool to determine the top 10,000 most expensive English-language keywords over a 90-day period. Then they organized the list by categories.
