It has been in news for a long time. Now it's reaching what might seem as a culmination. Google has received a settlement of a lawsuit regarding click fraud. But there is also some buzz about Congress taking it up for consideration. However, here's what Nicole Wong, Associate General Counsel, had to say-
Now that the preliminary settlement has been approved by the Court, all members of the class are being notified about the settlement. On May 19 and 20, 2006 (PST), a settlement administration firm sent an email notification (from email@example.com and with the subject 'Important Legal Notice Regarding Your Google AdWords Account') to all advertisers who purchased online advertising from Google between January 1, 2002 and the present.
I recommend that you carefully review the information in the email and visit the site provided by the administration firm: www.clicksettlement.com. On the site, you will find links to the official settlement notice and settlement FAQs, both of which are in .PDF format. To view these documents, you will need Adobe Acrobat Reader.
As we have said in the past, we work hard to manage the issue of invalid clicks, and continue to be very effective in detecting and filtering them in order to deliver outstanding ROI to our advertisers. The vast majority of invalid clicks are detected and filtered out before they reach our advertisers' bills; if advertisers detect additional invalid clicks, our click quality team investigates and provides refunds as appropriate. You can read more information about invalid clicks and how we manage them here and in the AdWords Help Center here."
