SEO Company Search Results - An Embarrassment to Google and the Other Engines
One of the central goals of all the major search engines has always been to limit the extent to which manipulative activity could affect the top search results. It's been my general opinion that there's no better place to start this enforcement than our field - search engine optimization - and the SEO companies that offer this service.

For most ordinary users, I suspect they probably just move on to the next query, but for those of us deeply embedded in the world of search and SEO, these noggin'-scratchers just keep on itchin'. I've collected these ten over the past couple months and figured I'd share them on the blog with the hopes of g...
Everything You Never Wanted to Know About Google Maps' Parameters
This guide came around as the result of a post I previously wrote for YOUmoz, which in itself came around as a result of a night of drinking and being sent an interesting Google SERP.

New Reality: Google Follows Links in JavaScript.
I must have missed something. I always thought Google doesn't see links inside JavaScript code. As Rand writes in the Beginner's Guide, JavaScript passes no ranking or spidering value and pages behind JavaScript navigation may never be found by search engines if they are not reachable v...
The PageRank Hierarchy, As Defined By Celebrities
A PageRank layman recently asked me how Google decides what site gets what ranking. Rather than bore him with technical tidbits from last decade's abstract, I thought I could better express the concept through a medium we can all appreciate: celebrities.The metaphor is a simple one: PageRank is all about the quantity and quality of inbound links, right? Well, the value of a celebrity...
