Reporting spam in Google’s index
I especially want to hear about webspam that you see in Google. The best place to do that is to go to http://www.google.com/contact/spamreport.html . In the “Additional details:” section, I would use the keyword “jagger1″ (that’s “jagger” and the number one with no spaces in between).
You see a low-quality site that is running AdSense
If you run across a site that you consider spammy and it has AdSense on it, click on the “Ads by Goooooogle” link and click “Send Google your thoughts on the ads you just saw”. Enter the words spamreport and jagger1 in the comments field.
