i remember history very differently. the old search engines before google analyzed only page content in isolation, which lead to SEO sites appending invisible blocks of keywords at the bottom or putting loads of barely related keywords in the page title. google was the one that managed to break this cycle with pagerank. suddenly, the spamword filled trash sites were worthless because nobody (of worth) linked to them. on the other hand blogs flourished, because their structure worked well with pagerank. it took a long time for the spammers to re-build their networks and strategies to adapt to the situation, but even then having a well-written and regularly updated company weblog usually did more for your search ranking than other SEO trickery.
