Link building strategy - my weak link!

[CalicoKitty2000]

Please help me understand link building.  I've read the articles on Moz, but they seem vague to me. Specific questions:

1. How do I get my webpage on good quality sites?

2. Guest blogging?  Good or not?

3. What about when people pick up one of our blog stories and publish it on their site with a link back? Is that bad now because it is duplicate content???

4. Forum posts with a link in the signature?  Good or not?

5. Directories - I get it that these are no longer good... are they severely negative? Should I take them down.

6. PR - Looks like this is bad... right???

7. Youtube - any value?

8. Pinterst, LinkedIn, Twitter, Facebook, Instagram?  Any value to backlinks here?

9. What about sites like redit?

10. Anything else I should consider?

Check out Brian Dean at backlinko.com (I believe Brian is also here on MOZ) - he has some excellent ideas for getting links from quality sites with good content creation.  Actually, he has some of the best ideas I have seen in a while.

Hope that helps!

I agree with DJ123. Also recommend John Cooper's link building site - Point Blank SEO. You'll find most, if not all, of the answers to your questions there.
