How Much Did Michael Jackson Rock the Web?

By Jenna Wortham

As news of Michael Jackson’s death began to spread last Thursday, the crush of people flocking to the Web for information overloaded several Web sites and services, causing AOL’s instant messaging service, news sites, Twitter and Wikipedia to buckle under the strain. But just how much traffic are we talking about? Compete, a Web analytics firm based in Boston, crunched some numbers and came up with a few data points to help illustrate the surge.

It found that there were 9.98 million queries for the terms “Michael” and “Jackson” across the top 25 search engines and news and social media sites in the week ended June 27. Compete said that was more than 24 times the number of queries for information using the terms “Iran” and “election” during the week before. Google, which said that its systems initially interpreted the spike in searches as an attack, fielded the most requests, handling 61 percent of the queries. Yahoo Music pulled in a hefty 45 percent of Web surfers seeking the pop maestro’s albums, music videos and merchandise, according to Compete. YouTube ranked a distant second with 23 percent. Compete said Yahoo’s dominance was probably a result of spillover from its coverage of Mr. Jackson’s hospitalization. Yahoo said its coverage broke traffic records, generating 800,000 clicks in the first 10 minutes that the story was posted. The increase in interest in Mr. Jackson’s legacy has been reflected in record-shattering sales of music, both online and at retail stores.
