Great explination of Google's PageRank

I just watched two videos by Rand Fishkin regarding Google's PageRank, and I think that these are easily the most succinct education about Google's Pagerank that I have seen in quite a while.

The first video, What's PageRank Got to do With It?, describes how Google uses PageRank for:
1. Crawling - How Google's spider determins what to crawl.
2. Inclusion - Divided into 2 pieces, importance and uniqueness
3. Freshness - How often content is updated, and therefore how often to re-crawl a page.
4. Ranking - how pages in Google's index are ranked.

IMO, the important comment to draw from Rand's video is that #4, Ranking, may be the least important function of PageRank, especially when anchor text, link quality, link source, etc are becoming less important or trustworth.

After the helpful education session, we can move on to Rand's next post, Whiteboard Friday - PageRank Part II.  Here's the information that you will find really useful, because Rand goes into how PageRank can help you optimize your site better.  So, rather than trying to translate the video, watch it for yourself:
