Twitter search and advertising startup platform operator TweetUp has announced today that its search engine for Twitter will be expanding to include bios and updates posted to other social networks, including LinkedIn and Facebook. Because the company will no longer be solely based on Twitter, TweetUp is changing its name to PostUp.
In April, TweetUp, which was incubated by incubated by idealab, opened registration for its bidded marketplace for real-time search, and in May the company launched its search capabilities on a number of sites at the TechCrunch Disrupt event, including at TechCrunch, Topix.com, and Businessinsider.com.
TweetUp’s search algorithms and marketplace aim to address the needs of both users and tweeters in a single search mechanism. In addition to algorithms that combine a variety of factors to determine relevance, tweeters will soon be able to bid on keywords in a marketplace very similar to what now occurs at search engines. TweetUp also offers any publisher embeddable widgets and other contextual layers filled with relevant live tweets based on given keywords. Now users will be able to source public updates from LinkedIn and Facebook.
Bill Gross, CEO of PostUp says that because most of the authorities that TweetUp are sourcing in its results post comments on multiple networks, it made sense to expand results to LinkedIn and Facebook. Gross adds that over the past few months, more than 12,000 tweeters have registered over 200,000 keywords to date, and impressions have been growing ar 100% per month. To date, PostUp has served over 700 million impressions in three months.
The change in strategy for PostUp isn’t surprising; it’s better to diversify your business model rather than being tied down to one platform (Twitter).
TweetUp has recently closed a $3.5 million first round of funding led by Index Ventures, and have taken investments from SV Angel (Ron Conway), First Round Capital, Betaworks, Steve Case, Jason Calacanis and Jeff Jarvis.
