Backlinks with blogger

I found that my competition has one blog in blogger pointing a lot of links to their main site...

I want to build one but my problem is content because we are using the writing resource for the blog on the site. So these are my ideas to post content in the blogger blog and get backlinks:

1. Post videos from youtube and the text transcriptions.
2. Posting the same posts from the blog on the main site.
3. Copying short and very recent posts from Facebook which text has still not been picked...
