BackType announced on it’s blog that it has been acquired by Twitter sometime back. BackType is a small social analytics start-up that aims to help brands and companies understand the business impact of social media, analyze the effectiveness and the value of engagement on Twitter.

We’re thrilled to announce that BackType has been acquired by Twitter! We’ll be bringing our team and technology to Twitter’s platform team, where our focus will be developing tools for Twitter’s publisher partners.

The financial details of the acquisition weren’t disclosed.

BackType offers real-time search for mentions of certain terms on Twitter. It has analyzed over 50 billion tweets, 10 billion links and more than 200 million Twitter accounts. BackType Team stated that by joining with Twitter, it will added insight to tens of millions of publishers around the world who communicate and connect with audience on Twitter.

BackType did offer some amazing technologies initially. They had developed a technology that had the ability to track a person’s comments posted on blogs all over the web. Entering the blog’s URL would give you an RSS feed of all the comments posted around the blogosphere.

BackType’s product BackTweets helps publishers understand the reach of tweets and content and how Tweets convert to potential traffic. Since the acquisition, BackTweets will now be offered to current users for free. However, BackType has closed new registrations for BackTweets and will discontinue the product and API services.

Twitter, on the other hand, might use BackType’s technology to help advertisers track the effectiveness and the value of engagement of Promoted Tweets.
