comScore, Inc., a leader in measuring the digital world, released its monthly analysis of U.S. web activity at the top online properties for March 2011 based on data from the comScore Media Metrix service. Green lifestyles were top of mind for many Americans in March as the country took part in the annual Earth Hour (March 26) amid rising fuel costs. Travel sites spiked as springtime rolled in, helping visitors to plan last minute spring break getaways and upcoming summer vacations.

“Green sites earned the #1 spot on the top gaining categories ranking in March - a result of Americans seeking ways to cut back on energy consumption beyond Earth Hour amid a backdrop of skyrocketing gas prices,” said Jeff Hackett, executive vice president of comScore Media Metrix. “Travel sites were also popular during the month as many Americans booked last minute spring break trips and looked ahead to plan summer vacations.”
