Yahoo has taken the lead over Google as the head of U.S. Web traffic for the month of July 2013 according to comScore's monthly rankings of the most visited sites online.

Yahoo runs and operates a collection of noteworthy websites that cover everything from movies, to finance, sports and its popular home page. The site raked in 196.6 million unique visitors last month, compared to Google's 192.3 million. Behind the two were Microsoft, Facebook and AOL, making out the top five.

It's important to note that these rankings aren't necessarily the best indicator of a companies well-being or business. One of the biggest problems with the comScore rankings is that they don't factor in mobile web access, which has been steadily on the rise for quite some time now. According to comScore, Google is likely to be back on top once the multiplatform rankings that it is currently working on, become available, according to the Wall Street Journal.

However, Yahoo coming out on top for the first time since May of 2011 is nothing to scoff at for the company. Yahoo recently acquired the popular blogging website Tumblr. This was supposed to bring a younger more active audience to the company. A significant victory for Yahoo comes from the fact that Tumblr was not counted in July to give it its number one spot. Tumblr ranked number 28 on the list of most popular U.S. websites, bringing in 38.4 million visitors.

In addition, Yahoo was not focused on beating Google in the U.S. this month. In fact, its focuses were elsewhere as it shopped around for engineers to beef up its site's functionalities. Chief Executive Marissa Mayer is putting her efforts into redesigning sites and apps like Flickr, Weather, Fantasy Sports and Mail.

While these rankings aren't necessarily going to put Yahoo ahead of Google in any significant way, it's a major PR victory in a time when the right buzz at the right moment can mean big things for a web company.
