That said, Yahoo is still far behind Google in making money from the people who visit its websites. After stripping out advertising commissions, Yahoo's revenue came to $1.07 billion in the April-June quarter. Google's, meanwhile, was $11.1 billion by the same measure.
Research firm eMarketer estimates that Google will generate $38.83 billion in worldwide digital advertising revenue this year, more than any other company. Facebook Inc. is at No. 2 with an estimated $5.89 billion, while Yahoo is No. 3 with $3.63 billion expected. EMarketer's figures include mobile ads, which comScore does not count in its Web visitor figures.
It's hard to say if July's figures are a blip or the start of an upward trend for Yahoo. The company is in the midst of a turnaround orchestrated by CEO Marissa Mayer. Mayer, who recently clocked in a year at the helm of the Internet company, has described her plan for Yahoo as a "series of sprints" that will take several years to finish.
Shares of Google Inc. climbed $3.20 to $872.53 in afternoon trading. Yahoo's stock rose 79 cents to $27.85.
