What do you recommend for the length of a first launch? 5 days or 7 days? My niche is social media and this product is on Linkedin. I will be doing an affiliate contest for overall leaderboard, some prizes for first to 100, 50, 25 sales, etc. If the launch goes well, I will also be adding some 2 day total contests in the middle of the launch to keep momentum going. What is everyone's experience with the length of launches and how does it affect whether affiliates would like to participate and promote for you? I appreciate any help! Thank you!
