What is Pixel Stuffing?
As global spending on advertising continues to increase, ad fraud becomes even more prevalent. Businesses are forced to devote portions of their resources to compensate for bad traffic, metrics, charges, and waste. Pixel stuffing is one of the easiest types of ad fraud for cyber-criminals to execute against organizations that don’t have professional anti-fraud solutions in place. Protect your CPM, CPC/PPC, and CPL campaigns by learning how pixel stuffing works and what you can do to prevent it.
What is pixel stuffing?
Pixel stuffing is placing ads, or an entire website, inside a tiny 1×1 pixel using an iframe that makes them invisible to the human eye.
A normal ad runs and impressions are counted for the legitimate ad, as well as all the ads stacked in the invisible pixel. Fraudsters receive compensation for those fake impressions, and they typically use bots to generate even more fraudulent impressions with the pixel-stuffed ads.
How does pixel stuffing work?
Pixel stuffing can be achieved in several ways, but the most common route starts with a fake website. The cybercriminals join an ad exchange to deliver and display ads. Then they load ads into a single pixel space on the website. Bots and viewers will generate impressions for the legitimate and illegitimate ads. The perpetrators will sell these marketing events to the ad exchange, and they’ll make money from each impression that’s served.
What are the threats posed by pixel stuffing?
Pixel stuffing, among other forms of impression and click fraud, can cause huge issues for businesses. It starts with charges for impressions that are not visible or not clicked on my a real human. As long as the number of impressions and the cost per impression aren’t too high, those charges often aren’t noticeable by advertisers.
But what happens when those charges skew the overall cost of actual conversions? Advertisers will discontinue their ads when they appear unprofitable, and they might lose one of their best marketing channels. This misinformation within their marketing strategy can cause catastrophic damage and confusion.
Ad fraud can cause companies to hemorrhage ad spend, often derailed promotional efforts on otherwise legitimate ad channels. Sales targets are missed because they’re misinformed, and leads are lost because they aren’t distinguishable from masses of fakes.
