Sometimes it's better to show people something instead of making them read. In today's world, time is a very limited resource. Being able to watch a short video about a product is something most web users look for today.
Developing a short video trailer for your Guide will not only provide an extra promotional push and get your potential customers excited about your content, but it will also provide the reading-averse with something they can watch.
Naturally, you may be leaning towards creating a complicated, and flashy video for your product, but some of the best promotional videos are done with nothing more than a webcam or smartphone. Kickstarter, a popular crowd-funding service, has noticed that campaigns with more polished videos tend to raise less money than those that are barebone, and minimal.
Your video can be as simple as sitting in front of your web cam and speaking about your Guide, highlighting why you are so passionate and knowledgable about the subject matter. But it can also be built like a traditional commercial with teaser content, and fun props. There is no guaranteed formula for success. Everyone's approach is different. The most important thing to consider before publishing a promotional trailer is whether or not it fits into your overall branding, and addresses your primary audience.
As a case in point, check out this amazing promotional videos created by Peter Walsh for his "Ultimate Kitchen Organizer" Guide:
Walsh's promo videos address his primary audience, they provide insights into what someone will see in his Guide, and they're upbeat. Videos can increase conversions significantly, as long as they illustrate the content effectively.
A little production value goes a long way with video content, but you don't need a $10,000 budget to provide something of value to your audience.
