Landing Page > Opt-in > Offer: This is usually the best method. You bring the visitor to your website or funnel system. You have a giveaway for email signup. The email signup starts an autoresponder sequence that provides more information, gains trust and closes the deal. Consider adding a bonus offer to set yourself apart from other affiliate marketers of the same product.
With drop shipping, you’re effectively partnering with a manufacturer or wholesaler to sell their products. This way, you don’t pay upfront costs to buy inventory, aren’t sitting on unsold items taking up expensive warehouse space, and don’t have to deal with shipping the products yourself. You simply create your site, fill it with drop shippable products, and drive in customers, with almost everything else done for you.
