TweetUp -- the Twitter-centric search and adverting network -- announced its official debut on Monday. According to TechCrunch, TweetUp's destination site ranks Twitter search results by time
(and a proprietary algorithm) to determine if a result should be ranked higher than other more recent tweets containing queried keywords. Users will also receive targeted paid-advertiser results
within that stream. According to TechCrunch, TweetUp's business model is based on a 50/50 revenue share system, which it considers to be "a pretty compelling offer for advertisers."
TweetUp also offers publishers embeddable widgets, and other contextual layers filled with relevant live tweets based on given keywords. Meanwhile, advertisers can use the TweetUp system to track
the specific Twitter clients running their ads, along with the number of impressions served, and aggregate of followers reached. TweetUp insists that it won't be affected by Twitter's plans to block
third-party ad networks, because it doesn't run ads directly in Twitter's stream. Rather, it inserts them into Twitter search results, which TweetUp generates itself.
