It's bad when your web searches include sites that are mainly marketing fluff, but it's much worse when that fluff has been hacked into otherwise legitimate sites. Well, Google has had enough of this attempt to game the system. It's tweaking its algorithms to "aggressively" cull hacked spam from results, leaving you only with sites that intended to include the content you're looking for. While the changes will only affect about 5 percent of searches when all is said and done, that could mean a lot if it helps you avoid compromised pages and the malware that might be lurking inside.
