About Realtime Search:

  • The social web is changing how consumers are exposed to and search for information. According to Twitter, 100 million tweets are created each day (as of Dec. 2010).
  • Today's most important (and fastest growing source of) content is being created and shared by key influencers within the social web. As a result, social graphs are quickly replacing PageRank as the new "signal" for what is relevant.
  • Topsy search results are powered by people publicly sharing content within the social web, ranked by influence so that consumers have relevant, realtime results that correspond to the keyword, article or topic they are looking for.
  • Topsy's platform is designed for true web-scale search and extensible to all forms of social content. Companies are turning to Topsy to process realtime data streams to enable social search capabilities within their sites and applications.
