How do MOST people search your social media content?

[mikemartel]

Do you know where most people search social media content, maybe find directly on YouTube, Facebook, Google+ or Instagram?
Is it through search engines?

Almost people search content on social networks from keywords, tags, groups, pages and profile names.

I am not sure content on social media can be used on this case unless it can be useful for search engines when someone searched there.
