If you want to learn more about how to rank well in Google and you want it straight from the horse’s Google employee’s mouth you might like like to check out some videos that Matt Cutts has recorded and posted in the last few days. At the time of posting this he’s recorded 6 on a variety of SEO questions. You can see the first 3 here and the second 3 here.
NB: I’m yet to watch them but will do so tomorrow afternoon. I’ve been doing a little lecturing at a local university the last couple of days and the sessions finish up tomorrow (it’s been fun but I’m looking forward to attempting to get life back to normal).
