Competing with YouTube
In many cases all you need is to be told how to do something. If you search for an answer to a problem you are likely to find a YouTube video showing you how. Often these videos are overly long and take an age for the solution to your problem to become evident and are more an excuse for the maker of the video
The use of YouTube in your own webpages
W3C do actually suggest this. I have even implemented a solution to provide some instructional videos linked from my Parish Council website.
You could always use Facebook or Instagram
The use of other Social Media should also be considered.
