Hi ,
Entireweb just emailed a newsletter to me which is all about linking. Some webpages noticed a drop in pagerank the last few months this is because Google is now valuating your site for BAD neighbourhood linking and 3 WAY linking. After reading this I was a bit angry because getting links and putting them online is hard work and Google just ignores your hard work if you do not follow it’s rules.
If you want to read this too just PM me and I will forward you the entire newsletter.
Best Regards
Rick
