Yahoo is again the top US web property, winning out against Google when it came to Americans visiting its sites at least once last month.
Research firm comScore said Yahoo had 197 million unique visitors for the month. This compared to Google's 192 million unique visitors in July.
Microsoft (180 million), Facebook (142 million) and AOL (117 million) made up the rest of the top five, respectively.
ComScore lists the top 50 web entities based on the total US online population of 225 million, so Yahoo had the impressive reach of over 87 percent.
According to ComScore, Yahoo was number one for the first time since May 2011 - music to the ears of new(ish) CEO Marissa Mayer.
Since arriving at the company Mayer has overseen a string of acquisitions, using the fresh expertise to try and get Yahoo back on a firm footing after a decline in leading edge services and a fall in web traffic, which affected revenue.
And before anyone asks: no, Yahoo's visitor figures do not include those of the recently acquired Tumblr. ComScore has measured those separately at 38 million, giving Tumblr 28th place.
After the Tumblr acquisition in May, Yahoo said it will continue to operate as a separate business with David Karp remaining as CEO.
In June, Google led in the comScore figures with 193 million visitors, with Yahoo on 189 million, demonstrating Yahoo's impressive leap through July.
