Okay, so I have a question that involves back-links. I'm slightly confused because there seems to be a lot of repercussions for doing it poorly. After searching the forums for about a month and a half, my question basically comes down to two things. What type of back-links and SEO methods should I be using? For example: -Wiki back-links -Yahoo back-links -Blog commenting (not really sure what this is still...) -Web 2.0 -back-links -High PR authority back-links -Social Bookmarking These are some of what I've read about. However, to specify my question further, what I really wanted to know is "What type of back-links should point to my money site"? From what I've read so far, it seems to be quite risky when choosing the type of back-links you want. If you have too many high quality/PR links, then you get penalized for over-optimization. If you have too many low quality back-links, then you get penalized for spammy links. Also, it seems that certain links should are "Tier 2" type links that should be pointed towards a a back-link for your website. For example, I see that there are services that sell Wiki back-or Social bookmarking back-links by the thousands. Are these supposed to point to my money site or be used as a "Tier 2" link? And if they are used as a "Tier 2" link, what type of original link are they supposed to point to then? I'm very, very confused over this matter. Can somebody please advise?
