In SEO news, the guys at SEOmoz aren’t taking the Penguin update from Google sitting down. Since Google isn’t providing any SEOs with any guidance on what is really going on with their latest algorithm tweak, SEOs are taking reverse engineering it into their own hands. While SEOmoz is far from the only SEO company doing this, they are the ones taking it public to challenge Google to refute it. While figuring out the entire update would be nearly impossible, they are focusing on link juice.
Supposedly, they have developed a tool, a rather pricey tool at that, which exposes spam links. While this could be useful to a webmaster, it is also a bit sketchy because who knows if they have guessed the algorithm correctly? It could be they have shot t a number too low which could lead to people removing valid links that do not create spam. What is important though is they are doing something.
The worry is that some webmasters will use the tool to try to sink their competition by reporting competitor sites for spam to Google in the hopes they get sandboxed or moved down the SERP rankings. With anything potentially good there is the possibility it can be used for bad. What most SEOs are recommending instead is cleaning out old invalid and broken links or those that are providing little or no link juice which is normal housekeeping anyway.
