If you believe many search results from Google are overloaded with spam and crappy websites, you are not alone. Finally, Google gets to pay some attention and, through Matt Cutts, the big boss in Google Search Quality Team announces that it will tweak its ranking algorithms to eliminate some of the most annoying spam websites.
In his today blog post, Matt Cutts admits the spam issue (while also gloating that Google does a good job at detecting it) and discloses some high level actions Google will take. Among these actions we’ll see a new document-level classifier that will better detect when an article is intended as a spam – repeated words which serve as over-optimization to rank higher in the search engines, automated blog comments (this really brings me pleasure, you have no idea how many spam comments I need to delete every day) and also a better detection of hacked sites.
Google will also tweaks its algorithms to better detect sites copying somebody else’s content which seem to thrive lately and also to detect “content farms”, websites that are full of material which is both low quality and also keyword stuffed, designed to rank high in the SERPs (Search Engine Result Pages).
Matt also said that new ways for users to interact with Google and report spammy websites will be provided (Google Webspam Report extension for Chrome being one of these venues). Let’s just hope a physical person is behind and check these reports, otherwise I can foresee a war between various competitor websites declaring everybody else as a spammy site
