In a Thursday announcement, popular microblogging service Twitter revealed that it has acquired Smallthought Systems – a data company associated with the manufacture of a cloud-hosted Web analytics application, ‘Trendly.’ Twitter has incidentally worked with Smallthought Systems in the past, and has also internally used the firm’s ‘Dabble DB’ product.

Noting that Smallthought System’s new Trendly app can parse Google Analytics data, Twitter Kevin Weil said in a blog post that Smallthought staff has “joined our analytics team and will focus on integrating ideas from Trendly into our current tools and building innovative real-time products for our future commercial partners.”

The acquisition - the financial terms of which remained undisclosed – and the resultant integration of Trendly features and technology into Twitter’s existing systems, will essentially give a boost to Twitter’s Promoted Tweets advertising program, which it launched in April, in partnership with Starbucks and Best Buy. The program allows companies to market their products and services on Twitter’s site.

Since the success of Promoted Tweets, like all other ad services, largely depends on Twitter’s capacity to evaluate the popularity and efficacy of the ads for the evaluation and optimization of the campaigns, Trendly as well as other Smallthought products are expected to make a notable contribution to Twitter’s new ad program.
