I'm trying to move away from backlinking to my blog to target specifically to each blog post. It's still too early to see any result yet. I guess the PR of each blog post is more important than the PR of the blog in term of SERP. how do you backlink? Do you backlink to the website/blog or to each webpage/blog post?
As above ^ I build backlinks to my homepage and deeplink to my popular category pages - with a decent sitemap and site structure the linkjuice gets passed to the posts
Well it depends on what you want to rank. Each page or post will take a different amount of inbound links to dominate the rankings for a specific topic or key phrase. So it might be better to rank highly for a few posts than on page 2 and beyond for many, traffic wise.
Same as above but I would also write a hub and or a lens for each post. This always gives me an extra boost.
Well since I am just now developing my site, I am backling to my main domain after the site gets a proper rank and traffic then I will start backlinking to my posts
It depends. But if someone need specific information I link to category where he can easily see the answer to his question.
