I have a number of 100-300 page sites that normally rank well for the topics these sites cover. This update my sites are all on the back pages as the direct result of people buying unrelated high PR domains and putting 1-3 page sites on them and linking them all together with anchor text. Cant google's algo see that these are all 1 page sites jammed with the same words? Maybe they could factor in a size of site filter that would kill these things. I checked tons of other topics and it's happening everywhere. PR and relevancy should be tempered with site size to filter this spamming out. It has gotten worse every update...But this time it is out of control. If this isnt stopped i see alot of normal SEO's will have no choice but to join the club and where will thius leave the quality of the index?
