The results were published in the site's monthly ranking of U.S. web activity for July 2013 which is based on data from the comScore Media Metrix service.
According to the researcher, Yahoo had a little over 400,000 more visitors than Google did in the month of July.
As Mashable points out, this is the first time Yahoo beats Google in this category since April 2011. However, the figures fail to include Tumblr in the results, which had about 38.4 million U.S. visitors during the month. In addition, the numbers do not reflect Google's continued dominance in search which accounts for about 67 percent of the market.
The other big winner this month was back-to-school shopping, a topic that seemed to be at the top of the list for a majority of Americans as revealed by a traffic increase in fashion and accessories sites as well as consumer goods sites for school supplies.
