Show producers recently launched internet special Just Rosie, which follows Helen Flanagan's feisty character as she attempts to make it big in the modelling world.
New Media Age now reports that the Just Rosie website has had over 260,000 unique visitors since launch, while 203,351 people have watched the special online episodes and bonus clips. In total, the site has received 1.6m page views.
Just Rosie was also recently broadcast on ITV2 in response to the success of the internet airings.
Ben Freeman, ITV's head of soap and drama, commented: "We know that Corrie fans enjoy playful digital experiences around the characters they know and love, and this adventure with Rosie Webster is a great example of innovative cross platform commissioning at ITV."
Coronation Street bosses have launched a number of other successful online spinoffs in recent months, including tram crash bulletins to tie in with the 50th anniversary episodes, Gary's Army Diaries and Ken and Deirdre's Bedtime Stories.
Rosie will bow out from Coronation Street in February 2012 as Flanagan has decided to leave the soap.
