Excuse me if this has been covered previously. I am just wondering if any developers would mind sharing their experiences regarding free for x amount of time style promotions. Does it noticeably increase exposure to your product? Is their noticeable spillover to other apps released under your name? Are shorter promotions more successful than longer or vice versa? Did you find any results surprising or unexpected? Ultimately, are you pleased with the results and would you recommend this promotional tactic to others?
