Google has written two spam related posts over the Thanksgiving period on the Google Webmaster Central Blog. The first was named hard facts about comment spam and the second was named generic cialis on my website?
The first post explains how having comment spam on your blog or web site can hurt your web sites ability to pass link weight to other web sites an internally. In addition, if you did performed the comment spam yourself and Google penalized you for it, then you will have to clean up that spam (somehow) and submit a reconsideration request. In short, Google is penalizing for comment spam on both sides of the fence and expect both sides to take action to prevent it. Otherwise, Google won’t rank either site as well as they should be in the Google index.
The second post talks more about using the fetch as Googlebot labs feature in Google Webmaster Tools to help detect if your site was hacked into. Often spammers will hack into sites that have vulnerabilities in order to inject malware, links or both into the site. They do this to artificially create links to their site, in order to help boost their Google rankings. Google wants to aid webmasters in detecting spam, discovering where it is on their site and then quickly remove it and patch the site in the future.
