Space Godzilla: Lessons in Monstering
It's a movie theme here on SEOmoz this week. After Rebecca's post on real movies, I'm going to talk about an imaginary one. It's a movie that would go straight to DVD, but might nonetheless be compelling for those of us who are search geeks. It's a battle between monsters - the might of Google pitched against some of the largest brands in the world. Anyone see Godzilla ...
Google's Top 100 SEOmoz Member Profiles
I was recently reading an interesting article by Portuguese SEM consultant/philosophical bear hunter, Carfeu, which brought up some questions about the Toolbar PageRank on SEOmoz members' profiles. The main question was: Why do some peop...
Unwritten Google Webmaster Guideline: Don't End URLs in .0
Many of you saw this post from seoco.co.uk this morning (or its Sphinn thread) about our Web 2.0 Awards being removed from Google's index. We noticed the same thing late last night and spent some time this morning going through what could have happened. We ...
Solving Duplicate Content Issues with Http and Https

Google Follows Nofollowed Links in SEOmoz Comments?
I may be totally wrong on this, or maybe I've overlooked some obvious explanation as to why the content on the end of nofollowed SEOmoz comment links has been indexed and ranked. Puzzling over this by myself and with friends hasn't produced any good conclusions, so I thought I'd throw this out there to the community. Nutshell: periodically, I'll search for my own name in search engi...
Is Yahoo Buying Text Links?
This was brought to my attention a few weeks ago, but I've only now been able to look into it. This site that rates schools across the nation is a useful resource for parents--it even won an award for "Best Family & Parenting Site." Looking at the "Glendale Schools" page, at the footer I see a link that says "Glendale Real Estate." ...
