What Spider.io does

Spider.io was a London-based ad fraud detection and viewability measurement company founded in 2011 by Dr Douglas de Jager and Dr Simon Overell. Its core products were an MRC-accredited viewable-impression measurement service and a botnet detection platform that identified fraudulent and non-human traffic across major US display advertising exchanges. The underlying technology used a patent-pending browser-optimisations approach that monitors how browsers allocate rendering resources to ad impressions, allowing measurement of viewability across Chrome, Safari, and Internet Explorer in any iframe environment — including nested unfriendly cross-domain iframes where the same-origin policy defeats geometric approaches. Spider.io additionally built fingerprinting and traffic-pattern tooling to identify ad hiding (0x0 or zero-opacity iframe slots), the Internet Explorer 6-10 mouse-cursor leakage vulnerability, and major botnet families such as Chameleon, TDSS, and Zeus, publishing detailed case studies with quantified financial impact.

The firm sold to enterprise adtech buyers on a subscription/contract basis through a direct field-sales motion targeting ad exchanges, ad networks, SSPs, DSPs, and publishers. Named customers and partners included Adconion Media Group, Legolas Media, Bannerconnect, DataXu, and media6degrees, with the service embedded into partner dashboards such as Legolas's platform and Bannerconnect's Bright. Marketing was built primarily on a research-publication engine (proprietary blog, guest articles in Wired, AdExchanger, AdWeek, ExchangeWire, WSJ) and on participation in the IAB Traffic of Good Intent Task Force, with MRC accreditation in May 2013 serving as the principal mid-funnel credibility milestone. In February 2014 Google acquired Spider.io to incorporate its fraud detection technology into Google's video and display ads products.

Core offering

Spider.io provided MRC-accredited viewable impression measurement for display advertising, using a proprietary browser-optimisations approach that measured whether ad impressions were actually painted to users' screens across all major desktop browsers and within nested cross-domain iframes. The company also offered botnet detection and ad fraud intelligence services that identified fraudulent non-human traffic (including Chameleon, TDSS, and Zeus botnets), hidden-iframe ad hiding schemes, and spoofed engagement signals across programmatic ad exchanges. Services were sold on a subscription basis to ad exchanges, networks, DSPs, SSPs, and publishers.

The core product was an MRC-accredited viewable impression measurement service that could measure whether individual display ad impressions were legitimately viewed across all major desktop browsers in any iframe environment.
