Everyone’s primary goal in search optimization is to get their own site’s content to rank first (or as close as possible to first) for specific keywords. If, however, you are having a bit of trouble doing that, it doesn’t hurt to help content you have created on other sites to rank well for similar keywords in search – just make sure that content is branded well enough so people know who to credit for it.
The following are three different types of media you can optimize on other networks with strong domain authority:
1. YouTube Videos
2. Flickr Photos
3. SlideShare Presentations
