TLDR; New to IM, built amazon site, want to start giving it some backlinks, looking for solid resources. So I'm fairly new to IM and brand new when it comes to anything SEO related. I have built an amazon affiliates website, nothing I'm really attached to but I just wanted to try it out and see if I could get myself some traffic and possibly some sales. I consider it to be more of an education than an actual attempt at income. I've got the site built and have a decent amount of content on the site. Where I didn't plan ahead was doing any kind of keyword research when deciding on what content to put on the site. My goal is to learn the keyword research and go back and adjust for this. Anyway, now that the site is about a month old and content has been dripped on it over the course of a month I want to start learning the actual SEO parts. I've been reading up on web 2.0s but it's like a mine field out there when trying to find content that will actually teach you something and not just try and sell you some spammy service. I understand that 2.0s contain content and provide a link back to your main page, but do they always just contain 1 link or is it better to have a few links from that page to the main page? Also, for tier 2 links, I think I understand that pointing multiple tier 2 sites back to your 2.0 is the correct way to do things. Am I mistaken? Are there any good resources, preferably videos, that teach this kind of information? Also, am I heading in the right direction or do I really need to focus on keywords for my main page before I start spending time on content for 2.0s?
