After Padna/Penguin, I hear a lot about quality over quantity for back links. They say that low quality links could harm you now etc.
Many pieces of advice here say good quality blog posts, good quality articles, relevant blog commenting etc. etc. But my problems with that are
1: It takes time to write a good quality article or articles, or read a blog article and write a relevant comment. (And with your blog comments you don't even know if they will be approved.)
2: Good quality sites, blogs etc. where we can post articles are limited, especially if you want them in a relevant niche.
3: There may be many good quality, and relevant sites/blogs where you can write articles, blog posts, or comments, but it takes times to find them
So, it is very time consuming and I could probably make only a few good links per day at best. But at the same time, you can't get #1 by only 100 or so quality links (unless they are REALLY high quality). So it seems you need more backlinks. For example, for answers/replies to a question on this site asking how many links you should build a day, I read many people here say don't make links too many per day, 10-20 should be fine. You may disagree with this of course, but my point is that it seems even 10-20 links per day is considered little here and it seems a lot of people agree with it.
So...my question is...how do you build "high quality" links that many? How do you find sources where you can put 10-20 links/day? How do you write good quality article a lot enough to make 10-20 links/day? To me, making even 5 would be really time consuming and I don't have time especially when what you do is not just SEO in the day.
I just read many posts/replies on this site saying "You just have to build good quality links" but I'm just at a loss for how you do it (I mean, good numbers of them when you have other things to do in the day).
Am I missing something?
