Yahoo now has 800 million monthly active users, up 20 per cent since Marissa Mayer took the helm of the then struggling tech giant in July 2012.
Mayer announced the milestone this week at the TechCrunch Disrupt conference in San Francisco, noting that 350 million of its monthly active users are on mobile.
Instead, most of the growth comes from the company's core products like search and Mail, she said. On mobile, Yahoo Mail is one of the company's most popular properties, along with news and finance. Internally, Mayer has placed a greater focus on the company's mobile products, increasing the size of the mobile team by a factor of 10 since she took over.
It seems her efforts are paying off. For the first time in more than two years, Yahoo this summer topped Google as the top web property in the US, according to recent data from comScore. During the month of July, Yahoo sites attracted 196.6 million unique visitors, while sites owned by Google drew in 192.3 million.
But while Yahoo appears to be on the upswing, the company is nowhere near where Mayer wants it to be. The CEO said it could take "three or more years" to get there by focusing on people, products, traffic, and revenue. Her strategy is to attract talented people who can build great products, which will attract users, and generate ad revenue.
So far, Mayer's overhaul effort has included revamping the company's logo, unveiling a new homepage, updating Yahoo Mail, and releasing the Flickr-enhanced weather app. The company has also been on an acquisition spree as of late, picking up IQ Engines to boost Flickr and the news app Summly, among others.
Yahoo's revenue for the second quarter came in at $1.07 billion (£677 million), a one per cent decrease from the same time period last year, though earnings landed at $335 million (£212 million), up from $228 million (£144 million) in 2012.
