Ask HN: Contemporary 2014 resources on SEO

Hello all, I'm asking what resources are you using for creating SEO-friendly website. The story about this question is that last such thread was 6 years ago [1] and I guess things have changed by now. Anyway everything I'm reading consists a lot of words like "may be", "usually", "somewhat" and other non concluding statements that make me feel the whole SEO-business is actually somehow a SCAM. I'm particularly interested in: 1. Infinite scroll navigation ( Should I include noscript tag and put pages links or what is the technique in general to make the pages indexed ) 2. How to replace javascript UI elements with crawlable links ( for example a price slider ) [1] https://news.ycombinator.com/item?id=277259
