I thought I knew a lot about SEO.... until I joined this forum. I love it here. So much so that I spend time on this forum during classes... I am in law school. Anyone willing to help provide me answers will make me extremely happy! I might even give you free legal tips sometime in the near future I also wouldn't mind if you merely posted a link to another forum thread or only answered one of my questions. It's just difficult to read through topics without understanding these basics: 1. What do people mean when they say "2nd tier" or "1st tier?" I keep seeing this but have no clue what it means. Specifically, I've been searching Private Link Networks and it seems to be a way to promote my backlinks? 2. What is an "auto-approve" article? I've seen members here promote their list of auto-approve websites, what exactly are they promoting? I assumed it meant websites that automatically post your article (with backlink)... but what type of person would care about a backlink from such a shitty website? 3. What the heck is a web 2.0 website? I've heard it used in the context of Facebook and other social media but many of those websites don't pass link PR?. which makes me wonder why members say to post articles in web 2.0 websites? For example, "blast your article on all your web 2.0 websites!" ...I don't see the purpose here. Any help is great help! Thanks!
