How Do I Share Videos?

Each social site is different. I suggest you dedicate a week to each of the major social sites to learn about each and how to build an audience on each, starting with Youtube which is actually a social site too.

In addition to building a following, each site also has their own search algorithms.

Building a following on social media takes a consistent effort over a period of time. For example for Twitter a common strategy is to follow the followers of leaders in your niche in the hopes they will follow you back. After a few days you need to unfollow those that didn't follow you back. There are limits to how many people you can follow and unfollow.

For Facebook, I suggest joining groups related to your niche and participate actively in each. As you become known, invite people to be your friends, building an audience of people interested in your niche. You may also be able to post your videos directly to the groups, depending on the culture of each group.

Once you get each social site set up you can use a site called IFTTT.com to automatically post your YT videos to each, although at first I'd use YT's social share buttons and do it manually.

I'd focus on these sites, one at a time:

Youtube
Reddit
Twitter
Facebook
Instagram
Pinterest

Each has their own cultures which you need to research and respect...

Also, check out which social sites IFTTT.com submits to and create accounts for the secondary social sites and use IFTTT to automatically submit to them.

There are multiple courses, reports, books and videos explaining how to use each social site for marketing which go well beyond the scope of this forum post.

You can share your video on Youtube, Veoh, Vimeo, Liveleak, Metacafe, Dailymotion, Myspace. Those are video-upload website. To get more traffic, you shouldn't forget facebook, G+, LinkeedIn.
