This article is intended for novice to intermediate SEO readers.

You may (or may not) be aware that Google loves Wikipedia. Due to this fact, not so long ago people were spamming wikipedia articles with links to their own websites to receive Google juice (ie: increase their Google page rank).

I want to let people know that wikipedia has recently (earlier this year actually) made it completely worthless now to add links to your own websites from wikipedia articles. Even if you do so, you will no longer receive any Google juice.

How did they do this? It was pretty easy actually. All they had to do was automatically add a "nofollow" tag to all links to external websites. This nofollow tag informs the Google crawler to not bother following the link, and thus Google does not attribute any juice to that destination website.

Make sense? If not, please let me know in the comments below and I will update this article.
