Google might be one of the most successful companies in the tech world, but that doesn’t mean that Larry Page and Sergey Brin are not permanently looking for ways to grow and expand their company.

Less than a week after integrating Zagat’s services in Google Maps, the Mountain View-based company has announced an even more important acquisition. Meebo will become Google’s subsidiary, after a transaction that many consider to be part of a strategy to expand and strengthen the Google Plus social networking service.

According to a still unconfirmed piece of information, Google will pay around $100 million for Meebo, a service founded in 2005 as a browser based instant messaging program supporting multiple IM services, including Yahoo Messenger, Windows Live Messenger, and AIM.

Meebo grew significantly over the past few years, and, aside from integrating in its IM program services like Facebook Chat or Google Talk, also launched a couple of mobile apps, a content aggregator and, most importantly, a toolbar which can be easily added by publishers to their websites.

Google’s plans with Meebo have not been revealed, but it’s safe to assume that the search giant will use at least a part of Meebo’s crew to expand the reach of Google Plus. In fact, Google has released a short statement saying that “with the Meebo team’s expertise in social publisher tools, we believe they will be a great fit with the Google+ team.” and “we look forward to working with the Meebo team to create more ways for users to engage online.”

Naturally, we don’t know what will these new “ways for users to engage online” be, but we will probably see a fresh Google+ toolbar coming in the future. Either that or Google will be trying to unify its messaging platform by bringing together G+, Talk, and Voice, which would be even cooler.

The transaction hasn’t been sealed just yet, but all the formalities and technicalities are expected to be done very soon. While this is a beneficial deal for both parties, there will be a few people suffering from Google’s newest acquisition. No, we aren’t talking about Google’s competition, but about some of Meebo’s employees in the sales and marketing departments, who will reportedly be laid off after the transaction will be officially completed.
