Updated Webmaster Guidelines
Philipp Lenssen points out that Google Slightly Adjusts Webmaster Guidelines on his blog/forum where I am much lesser contributer. In his post Phillip wonders, “I wonder if there’s any deeper meaning to this…?”, in relation to their inclusion of three simple words, “or otherwise penalized.”
This is only my opinion, but I think this change has a lot to do with the ever changing world of fighting web spam. While on the surface it may appear like they are letting up on spam by not completely deindexing a site and just penalizing it, I think quite the opposite. In the old days if a site was banned you may get Gray Barred, or have your page rank disappear along with your pages. Then the Gray Bar disappeared. Recently this change has been noticed in dozens of forums regarding the -30 penalty, the -950 penalty, or the “q” factor.
Part of any gray or blackhat activities has to be experimentation. Push the envelope and see where the limits are, push back and see what you can get a way with. By reducing the site-wide ban and focusing more on penalties are nearly undetectable Google has removed the feedback element to this testing procedure. They’ve in effect added more confusion to the mix. No longer will it be as easy as seeing no results from the site: command to know if you’ve been caught but a penalty may just appear like a symptom of low ranking pages. The simplest cure for low ranking pages is to improve them, which everyone wants anyway!
I’ve said before and I’ll say it again, if Google wants to expand its fight on spam there are two simple things they could do. #1) is show each and every page of a site when someone uses the site: command, no matter if it’s a piece-of-crap or not and #2) Just do not return those pages in any natural search results. Doing these two things will keep the spam sites scratching their heads more than learning the aspects of the algorithm.
