You have to remember that on Twitter, you only have 140 characters to work with. (At least for now–who knows what will happen with this 280 character limit in the works.) Your link takes up 23 characters of your tweet, even when you don’t use a link shortener, so you have 117 to say what you want to about the product and disclose that it’s an affiliate link. So you need to be short, sweet, and to the point.
Video is the most powerful form of advertising. It allows consumers to see and understand products before hitting the purchase button, and as visual creatures, we can’t help but watch a well-made, captivating video. Just think about it — video has only been around for about a century, but now it’s everywhere. We have Snapchat videos, 3D movies, videos on our Facebook walls, and more.
Keep conversations centered on the topic of your choice - in this case, related to your affiliate program - but don't be afraid to show a little of your personality in your tweets. Remember that as long as you don't offend or annoy anyone, people are way more likely to form a bond with a publisher who doesn't just push his or her affiliate programs, but also likes to educate, inform and entertain.
The online lead generation is a multi-billion dollar industry. Done right it can be far more profitable than many imagine. Everyone that I know that is in the business and knows what they are doing, for the most part, does 6-7 figures. While that's a huge range, much comes to one's ability to scale and effectively build / manage the infrastructure needed to scale.
