Since when? Google is happy for seo to be done on sites if it helps users and search engines find their way round the site. Google is fighting spam and unethical seo would be a correct statement.
I like at least 20% of links to be pointed at sub-pages, seems to help spread the pr around the rest of the site.
PR is related to more than just backlinks. PR is related to: 1. Backlinks 2. Number of links on page containing backlink 3. PR of page containing backlink If you want a proper explaination I suggest reading Google PR explained.
links, links and links...improve your link popularity...submit your site to link directories...create articles and submit them to article directories and link exchange with quality, relevant and trusted links....
Is there a one stop shop or book that explains all IM techniques? My brain is about to explode. I learn bits and pieces, here and there. Any ideas?
