I ran through some forums and comments related to SEO, and i see that the majority of webmasters believe in urban legends regarding SEO. I also noticed 80% of information related to SEO is wrong. They are all scared about negative SEO, comment posting, duplicate content, trading links, reciprocal links, off topic links. To me, it is crazy to see the propaganda in SEO websites like SEOmoz. On the other hand, it is good for us, because thanks to the stupidity of some people we can get pagerank without suffering from competition. Just to debunk some rumors. 1. reciprocal links: at the bottom of cnn.com there is a link to cnnchile.com. It means that every cnn.com page has a link in the footer with cnnchile.com. I guess there Houndreds of thousands links since there are many articles created everyday. This a reciprocal link and also a sitewide link on both cnn.com and cnnchile.com. Cnn.com is a PR8 and cnnchile.com is a PR7 2. There are pages on the net where links are hidden in a span tag: That's links that don't appear on the page but they appear in the source code and they are followed by googlebot. Websites get a lots of google juice thanks to those hidden links. 3. External links: the google blog (googleblogATblogspotDOTcom) has 60 external links on its main page and it possesses a PR8 4. Comment posting: googlebot reads comments, googlebot follows comment links. On the Google Inc Webspam chief team Matt Cutts blog, there are comments, and there are also links (with nofollow but links) 5. off topic links: If there would be an off topic links penalty, news website would be heavily penalized because they may have very different links on the same pages due to the diversity of article topics. One can be about child birth, another can be about unemployment. The two links may be in the same article... 6. Penguin or Panda: To me, there is no penguin or panda issues. The issue is related to the competition. If you have PR1 or PR0 pages, you are in competition with many pages but if you have a page with a pagerank 8, you really don't care about penguin or Panda. To be successful, there is a big need of links, wherever they come from, whatever they are.
