Google Gets Hot Again

In that regard, the company's forays into the related display, video, and mobile markets will take center stage.

Investors will be looking for more commentary on the regulatory approval process surrounding Google's proposed takeover of DoubleClick. During the quarter, Microsoft(MSFT Quote) spearheaded an aggressive campaign to convince legislators that a combined entity would give Google too much power and threaten user privacy.

Google also introduced ads on its YouTube video-sharing service. While the ads are still in a trial stage, the company's indication of how they're performing -- and when they'll start helping earnings -- will be important.

Finally, Google's plans for the mobile arena will be closely scrutinized. Speculation about what the company will do has been rampant, with competing theories speculating whether the company will introduce a handset or limit itself to providing software.

Along with another strong quarter for search, Google will have to deliver some sharp thinking about how it plans to move beyond its core sector if it's to keep the support it has recently won.
