Increasing Conversion Rates Boost Your Revenue ("Reduce Risk")

Friends, having looked at Congruence, Customer Testimonials, Urgency, A/B Testing and CTA Testing ... which other techniques can we use to increase conversion rates? One answer is to reduce actual or perceived transaction "Risk" among prospects and current customers. For a Landing Page "Opt-In" request clearly state that you will not share the person's contact information with others and will not put them on an email "spam" list. Moreover, they can "Opt-Out" at any time. For product or service purchases risk reduction methods include a no questions asked "30-day money back guarantee", a "try then buy" process or even an "extra incentive" if the buyer is not 100% satisfied (e.g. a full refund plus a bonus ... such as cash, a complementary ebook, white paper, etc.).
