As markets mature, fraud is sure to follow. Google and Apple both have their share of problem to solve, from online browser and YouTube click fraud for Google and App Store gaming issues for Apple.

From the DoubleClick blog:

This is a fight we’ve taken seriously from the beginning. Over the years, we’ve invested significantly in the technology and talent to prevent fraud and create greater accountability online. For example, we put extensive resources towards keeping bad actors out of our ad systems — last year alone, we turned down millions of applications from sites looking to join our network because of suspected fraudulent activity. We also introduced new measurement tools, like MRC-accredited Active View, which lets advertisers buy only those ads that are viewable on a page. Active View offers greater peace of mind to all media buyers, but is especially important for brand marketers who want to know, first and foremost, that their ad has a chance to be seen.

On the spider.io acquisition:

Our immediate priority is to include their fraud detection technology in our video and display ads products, where they will complement our existing efforts. Over the long term, our goal is to improve the metrics that advertisers and publishers use to determine the value of digital media and give all parties a clearer, cleaner picture of what campaigns and media are truly delivering strong results. Also, by including spider.io’s fraud fighting expertise in our products, we can scale our efforts to weed out bad actors and improve the entire digital ecosystem.
