Google's New Search Algorithm
The new google's search algorithm was supposed to adversely affect content farms like eHow, ezarticles.com, etc, but looks like eHow was the (lucky?) winner...
"One thing that surprised me was how well a few particular sites appear to have fared in this update," added Russo. "eHow, for instance, was a site I expected to see impacted negatively - but that wasn't the case. On the set of queries I tracked, eHow saw a substantial increase in many places. It's possible that this is simply because less authoritative directories that ranked above it were devalued; it's also worth noting that many of my queries included "how to" phrases, which are eHow's bread and butter. That being said, it's pretty clear that eHow wasn't hit by this particular update. Wikihow also saw a substantial improvement on my set of keyphrases."-Jeffrey Russo
