We uncover inefficiencies in your media spend using benchmark-driven analysis and performance tracking.
Powered by our proprietary Netscore® platform, we compare your costs and results against market standards, ensuring full contract compliance and smarter investment decisions.
We audit all media. Full stop. We lead the field in digital media auditing and deliver modern, curated, and insightful offline audits as well. Our work is focused on delivering tangible value because that’s what a true audit must do. Reports are detailed, clear in their conclusions, and packed with actionable recommendations. We don’t just review media - we drive performance.
Online
We analyze whether your digital ads are truly seen, safe, and regularly optimized. Full audit of CPM, CTR, fraud rate, and media delivery.
TV
We assess your TV campaigns in detail: cost per Target Rating Point and Gross Rating Point efficiency, spot placement, delivery accuracy, and weekly campaign strategy – benchmarked against market norms.
RADIO:
Radio buying is often overlooked – we verify spot volumes, timing (dayparts), and CPM.
Print
Do your print ads match what was promised? We verify placement, size, rate, and distribution, ensuring media compliance down to the detail.
OOH
Out-of-home campaigns are complex. We verify that all booked panels are displayed, rotated as agreed, and priced reasonably.

More about Media Audit
Quadra™ Benchmarking
We take a deep dive into the agency work in your media buy, both in cost and quality aspects. For markets where we have the cost pools we can directly benchmark prices to the similar advertisers in spend. For markets where we get the access to syndicate research on competitive activity, we analyse jointly selected quality KPIs of campaigns to the whole market or to the quality pools in the absence of total market data – all of that in our sophisticated software platform to manage that for any medium in any market - Quadra. Thanks to this approach we are able to quantify the performance of the campaigns vs. not only competitors but the total market.
It optimises investments between communication channels and activities, as well as within these channels. For example, for TV: Based on previous ROI, carry-over of TRP ad price, it plans how much budget is most optimal, what levels of weekly TRPs should be planned, and how to plan the breaks. Depending on the data granularity, it can also suggest the best TV channel split. Thus, it also helps with negotiations with media owners.
