This format can often be the major contributor to increasing your online impact. A short sharp burst of information directed at the user who is short on time/energy, can stimulate a fast reaction and draw them more closely to your goals.
In our experience the best results come from sites that are really useful, or at least entertaining and ideally topical, linking to a bigger news worthy item / event / offer and supported by a clear ‘call-to-action’.
Speed to market is also important as they tend to have a relatively short life span. They should be monitored by comprehensive tracking tools, naturally showing as much user activity as possible, as well as the performance of any revenue streams.
The inclusion of games/animated graphics/video can maintain interest and allow the us to blend in other visual devices that do not readily fit within the usual corporate environment.
