A new report from NumberEight suggests that traditional IP-based advertising models often default to near 50/50 gender splits, potentially masking true audience demographics. The analysis, which utilized ID-less modeling against traditional methods, highlights discrepancies in how effectively different systems identify consumer profiles.
Why it matters
For advertisers, these findings mean that current targeting strategies may be built on inaccurate audience data, directly impacting campaign ROI and market penetration. Relying on legacy IP-based models risks over- or under-serving specific segments due to imprecise gender identification.
NumberEight analyzed 7,013 shows across a cohort of 3 million unique users. The study noted that IP-based models repeatedly returned gender distributions near a 50/50 split, while ID-less methods provided significantly higher precision, such as identifying an 82% female audience for one game.

NumberEight
A data provider focused on developing ID-less methods for tracking mobile and connected TV audience demographics.
The details
The report, Demographic Data in Advertising: Traditional vs. ID-less Methods, compares legacy IP-based models with modern ID-less approaches. These ID-less systems synthesize contextual signals, behavioral data, and first-party information to move beyond the limited resolution of IP matching. By failing to account for nuances in user behavior, traditional models can misattribute audience composition, leading to inefficient spend and poor campaign alignment.

Market Landscape
This report follows the broader industry-wide transition away from third-party cookies that has forced a scramble for alternative measurement tools. The findings suggest that existing IP-based solutions may provide insufficient accuracy compared to emerging contextual and behavioral modeling.
Operators should review their ad-buying platforms to determine whether they rely primarily on IP-based demographic targeting or more granular behavioral signals. Comparing performance metrics across these different data sources can reveal if your current audience reach is suffering from misidentification.
The takeaway
Legacy IP-based targeting tools may be masking the true composition of your audience by defaulting to generic distribution patterns. Audit your current marketing analytics to confirm whether your targeting methods rely on outdated assumptions or specific, observable user behaviors.
