Yahoo chief executive Marissa Mayer is working on a plan to persuade Apple to ditch Google as its default search engine in favour of Yahoo, according to a report.
Mayer's effort is in advanced stages, with a detailed pitch already prepared for Apple executives, technology news site Re/code reported, citing sources within Yahoo.
Yahoo senior vice-president of mobile and emerging products, Adam Cahan, is reportedly working on the effort too.
Mayer, a former Google executive, has managed to get support from some Apple executives, including long-time acquaintance Jony Ive, according to Apple Insider. "Mayer has supposedly wrangled support from a few Apple execs including long-time acquaintance Jony Ive," Apple Insider said.
Design head Ive exerts enormous influence over strategy and products in engineering and design-heavy Apple.
Google search, which has been the default search engine in iOS and powered Apple's Safari web browser used on iPhones and iPads for quite some time, pays Apple about $US1 billion per year for traffic driven to its servers and subsequent ad network, Apple Insider said, referring to the same rumours.
Apple's decision to stick with Google's services over the years also reflects a desire to maintain a familiar user experience, the blog said.
Yahoo on Wednesday again posted anaemic quarterly revenue growth as the internet company's advertising business continues to lag its rivals, nearly two years into Mayer's comeback effort.
Mayer is trying to revitalise Yahoo's business, revamping many of its web products, but its ad sales business continues to struggle while rivals such as Google, Facebook and Twitter continue to post strong, double-digit revenue growth.
