Yahoo! ( YHOO) is expected to launch its new homepage Tuesday, months earlier than previously planned, according to published reports.

The new design is expected to be available as an option for users when they go to as soon as Tuesday, the Wall Street Journal reports, citing people briefed on the plans.

The retooled page will be introduced in the U.S. on Tuesday; the U.K., India and France later this week. It will roll out to the rest of the world during the next year, according to the Associated Press.

The Internet company has tested several versions of the new page for months, but last month said that it wouldn't be completed until this fall. The company was planning on unveiling it as part of a broader rebranding in late September or October, the people familiar with the matter said, along with update to Yahoo!'s email program, the Journal reports.

The biggest change in the new design is a left-hand menu users can customize with links to dozens of potential third-party software developers may seek to build, such as micro-blogging service Twitter, and Google's ( GOOG) Gmail, said the people briefed on the plans.

Yahoo! is hailing the new look as the biggest change to its front page since the Web site launched 15 years ago. Yahoo! last overhauled its home page in 2006.

Carol Bartz, hired as CEO six months ago, has predicted the revised home page will help revive the company by re-establishing its Web site as an Internet gateway for more people, AP notes. Yahoo!'s Web site remains among the Internet's busiest. More than 570 million people worldwide came to Yahoo! in May, according to the most recent data available from online research firm comScore.

Yahoo! is expected to report second-quarter earnings Tuesday after the closing bell. The Internet search giant is expected to report earnings of 8 cents a share on revenue of $1.14 billion, according to a Thomson Reuters poll of analysts.
