A day after unveiling its most recent quarterly earnings, Yahoo! (NASDAQ: YHOO) is again making headlines. The company announced that it has added to its rapidly growing list of acquisitions by purchasing AdMovate. The early-stage company concentrates, in its own words, on the delivery "of personalized, hyper-local targeted offers through the mobile channel." The terms of the deal were not disclosed.

The acquisition is in line with several of Yahoo!'s recent purchases concentrated on the mobile computing sphere. Earlier this month, it announced it had bought app makers Qwiki and Bignoggins Productions.

The AdMovate deal should also help shore up the company's advertising, a point of concern to many investors. In an official company blog entry posted on another recent acquisition, Tumblr, Senior Vice President of Display Advertising and Advertising Technology Scott Burke admitted as much by saying that "this acquisition is part of our efforts to invest further in our ad tech platforms -- Apt, Genome, and Right Media -- and make buying easier for advertisers and agencies."
