Videos can make learning easier and more memorable as they involve more than one of your senses.
You are listening and watching and possibly also taking notes, all this can help you to remember the training more effectively.
However people differ in the preferences of learning styles, what suits you? Quick 1 or 2 minute training videos are very useful and a lot of information can be covered in a short time on video.
They can easily be stopped and started and replayed if necessary to understand a point.
These short videos need to take just one aspect of the training and focus on that.
Make a collection of these short videos to cover a more complicated task and combine them together as a set.
as an illustration EzineArticles offer 1-2 minute training videos to help their authors improve their articles.
Longer training videos, often around 10-20 minutes are used for longer presentations but if they get much longer, the attention span suffers and you are less likely to remember all the details.
Usually the beginning and end remain the best remembered parts.
However it does depend how interested you are in the topic and how good the presenter is as to whether it holds your attention or not.
For example Weebly offer training tutorials for their free websites.
These are probably 20 minutes long.
Of course it is possible to make PowerPoint presentations but it will help your customers to relate to you if you begin and end with a full face shot.
If you show yourself as a person, even briefly, it will help your conversions.
Generally people like videos because they are easy to watch, especially now as many people use phones and other mobile devices which are smaller and make reading articles more difficult on the move.
If you are selling your videos you can also make transcripts of your videos so customers have the choice of how they learn.
Another simple way to make videos, is to video an interview, maybe interviewing an expert in your niche or perhaps a customer who has had great success with your products.
Webinars and workshops can be videoed, these can be given away as bonuses or sold, or even to encourage new customers.
If you give away fantastic offers new visitors are impressed and are more likely to trust you and purchase your products in the future.
If your videos are of a good quality and informative about a much-needed and popular topic, you have just made yourself a good saleable product.
I have just discovered Sarah Staar' s videos on YouTube.
On reviewing them I have noted how professional her videos have become over the years, they are also very informative.
So begin now and learn to make good videos as the YouTube following is massive and will only get bigger.
As an extra benefit Google owns YouTube so you will be automatically increasing your rankings - don't forget keywords in your titles and description boxes.
