We made a video at SMX Advanced with Stephen Spencer recently where we discussed (among other things) some changes expected(?) to be coming to Google in terms of the no-follow attribute.  These no-follow changes have some pretty significant implications for lots of things, first and foremost though it seems these changes are specifically geared to mitigate, to some degree, the effectiveness of PR sculpting.

A week or so ago, some people noticed some updates to Google Toolbar PageRank scores. It was unconfirmed however if this was an official update. Matt Cutts eventually confirmed on Twitter that it was indeed a Google update.

Users of the Google Toolbar will see updated PageRank values for websites become available over the next few days.

Recently a lot of people have been asking me questions about article marketing: what is it and how does it work?

Article marketing is the act of writing short articles, generally 1,000 words or less, and getting them published on the Web or in ezines. Generally you don’t get paid for these articles, but the ROI is that you get links from the article to your Web site. Since incoming links from relevant Web pages helps your search engine visibility, this is a good thing.

Matt Cutts told Mike McDonald of WebProNews about something new from Google: the search advertising company opened a little help center on the topic of nofollows and links.

For a while now webmasters have fretted over why all of the pages of their website are not indexed. As usual there doesn’t seem to be any definite answer. But some things are definite, if not automatic, and some things seem like pretty darn good guesses.

When the original PageRank algorithm was conceived, it was built around the a mathematical formalization called random walk or RW.

An update to the Google Directory has webmasters puzzling over an apparent discrepancy in PageRank scores.

I know a segment of my readers are sick to death with anything to do with Google PageRank updates, and I haven’t even bothered mentioning the most recent update up until now… there wasn’t really anything newsworthy in it.

One of the more entertaining aspects of the entire paid links debate is Google is pretty quick to dole out the punishment, even though in many cases they haven’t taken the time to get their own house in order.

Methicillin-resistant Staphylococcus aureus (MRSA) poses a deadly threat to people, especially hospital patients. One effort to track infections in a facility would utilize Google’s PageRank algorithm to do so.

The Guardian newspaper have today written an article titled Is Google a Grinch or a good guy?, which asks many UK SEO’s (myself included) for their views on the recent Google paid link debate.
