As the search engine giant works to expand its smartphone and tablet based audience, its acquisitions continue.

Yahoo! has just revealed its most recent step in widening its audience of smartphone and tablet users in its purchase of the mobile marketing platform, Sparq.Yahoo Mobile Marketing

This allows users to be able to more conveniently toggle among their smartphone apps.

This is far from the first of the acquisitions that Yahoo! has made recently in the mobile marketing area. In fact, this is only one of a growing number of small startups that are being absorbed by the search engine giant in its efforts to move into the smartphone friendly channel more effectively. The primary benefit of Sparq is that it allows its users to be able to switch from one app to another while using their smartphones. This could be highly appealing to marketers because this capability is believed to help to increase the app usage from the owners of mobile devices.

Sparq integration into Yahoo! could also help the company to use mobile marketing for monetization.

According to the founder of Sparq, Jesse Chor, who is also the company’s CEO, “We are uber passionate about mobile — we’ve been striving to build the best mobile platform possible, and are excited to continue upon that goal with Yahoo.” Chor went on to express that “Words cannot describe how ecstatic we are to be joining such an amazing team with such an inspiring mission. We see endless opportunity ahead.”

The earnings at Yahoo! haven’t been exceptionally good over the last while. During the last quarter of 2013, the company’s reports showed that its earnings had fallen by 91 percent when compared to the same time a year before. That said, one of the reasons that the earnings were as low as they were was that the company had spent a massive amount of money on the acquisition of startups. In fact, in the last quarter alone, there was $163 million spent by Yahoo! on purchasing other companies.

In December, the company took in a number of companies that could contribute to its mobile marketing strategy, including PeerCDN, a content-speeding startup, Evntlive, a startup for “virtual venues”, and SkyPhrase, a natural language software startup that has been compared to Siri.
