How do you prevent invalid clicks and impressions?

Google specialists carefully monitor clicks and impressions on Google ads in order to protect your interests as well as those of our advertisers. To do this, Google use both automated systems and human reviews, analyzing all ad clicks and impressions for any invalid click activity that may artificially drive up an advertiser's costs or a publisher's earnings.

Google's proprietary technology analyzes clicks and impressions to determine whether they fit a pattern of use that may artificially drive up an advertiser's costs or a publisher's earnings. Google system uses sophisticated filters to distinguish between activity generated through normal use by users and activity that may pose a risk to our AdWords advertisers. Some examples of this activity include clicks or impressions generated by unethical users, automated robots and traffic sources, and publishers encouraging clicks on their ads. This system enables Google to filter out most invalid clicks and impressions, and Google advertisers are not charged for this activity.

In addition to Google automated system, Google have a team dedicated to detecting invalid activity using several specialized tools and a wide variety of techniques based on extensive experience tracking and monitoring user behavior and analyzing scenarios. Google continually upgrade their detection mechanisms to proactively combat invalid activity.
