You should aim for high PageRank Links: Myth.
Of course you want links for high PR pages, but low PR pages also count. In fact, it will look more natural for Google if you have backlinks from a range of PR pages.
Links that aren’t relevant don’t count – Your backlinks have to be “relevant” or theme-related to your website: Myth.
Links from pages with content related to yours are better, sure, but that doesn’t mean links from non-related won’t count.
Links that aren’t indexed don’t count: Myth.
Google crawls a new page, decides the page isn’t worth indexing but still follows the links on it and credits anchor text accordingly.
Link Buyers Get Punished: Myth.
Every time you get a new backlink you spend money: either you spend your own time writing an article, submitting to directories, posting on Forums, or if you pay someone else to write your content (link bait). I don’t think Google is going to check each and every site to see if it’s buying links; in fact I’ve heard of sites actively buying links, were reported to Google and nothing was ever done.
Google actively checks IP’s: Myth.
They may check it upon a manual review but not on a bulk basis.
You have to vary your anchor text: Myth.
Google will never punish you if your anchor text is always the same.
If you build links fast, you will be penalized by Google: Myth.
Of course if you use an automated link building method and build thousands of links per day it may get Google’s attention… However, nothing will happen if you build a bunch of links every day.
If you link is not on a PAGE with PR, it won’t count: Myth.
Link juice will come from the PR and authority of the domain, even if the page itself is PR: n/a.
If you don’t see your links in a “Backlink Checker” tool, Google hasn’t seen them either: Myth.
Google “see” your links and credits them much sooner than you cca see them in backlink checker toos. What you will probably see is your keywords getting higher in the SERPs.
Google “knows” about and has devalued links from Social Bookmarks, Web 2.0 properties: Myth.
Google credits the links for their value, either they are from “normal” websites, social networks, blogs, directories or forums.
