Company Overview
We are
a leading digital media quality company offering advertising measurement, optimization and publisher solutions. Our mission is to be the global benchmark for trust and transparency in digital media quality for the worlds leading brands,
publishers, and platforms.
Through our cloud-based technology platform and the actionable insights it provides, we deliver independent
measurement and verification of digital advertising across all devices, channels, and formats, including desktop, mobile, connected TV, social, display, and video. Our Quality Impressions® is
a proprietary metric that helps ensure media quality standards. To be counted as a Quality Impression, a digital ad must be viewable, by a real person rather than a bot, in a brand-safe and suitable environment within the correct geography. The
viewability and invalid traffic filtration aspects of Quality Impression are accredited by the Media Rating Council (MRC) across desktop and mobile platforms.
Without an independent evaluation of digital advertising quality, brands and their agencies previously relied on a wide range of publishers
and ad platforms to self-report and measure the effectiveness of campaigns without a global benchmark to understand success. We are an independent, trusted partner for buyers and sellers of digital advertising to increase accountability,
transparency, and effectiveness in the market. We help advertisers optimize their ad spend and better measure consumer engagement with campaigns across platforms, while enabling publishers to improve their inventory yield and revenue.
As a leading digital media quality partner, we have deep integrations with all the major advertising and technology platforms including
Facebook, Instagram, Google, YouTube, LinkedIn, Amazon, Microsoft, Pinterest, Snap, Spotify, TikTok, The Trade Desk, Twitter, Xandr, and Yahoo.
Our platform uses advanced artificial intelligence and machine learning technologies to process over 100 billion daily web transactions
on average. With this data, we deliver actionable insights and analytics to our global customers through our easy-to-use reporting platform, IAS Signal, helping brands, agencies, publishers, and platform partners improve media quality and campaign performance.
