What is the purpose of mako_uid?
The mako_uid cookie is a third-party tracking cookie deployed by Eyeota (a Dun & Bradstreet company since 2021) as part of its audience data marketplace and Data Management Platform (DMP). It functions by assigning a unique identifier to a visitor's browser, which allows Eyeota to track the visitor's browsing activity, page views, and interactions across multiple unaffiliated websites.
The primary purpose of this identifier is to aggregate behavioral and demographic data to build robust audience segments and profiles. These audience insights are then made available to marketers and advertisers to facilitate real-time bidding, deliver personalized programmatic advertisements, and optimize cross-channel marketing campaigns. The data gathered helps match users with relevant ads based on their inferred interests and previous online activities.
What are the Privacy Risks of mako_uid?
Risk Level: Medium
The mako_uid cookie is classified as Medium risk because it operates as a persistent, third-party behavioral advertising identifier on the eyeota.net domain. According to Eyeota’s official privacy documentation and their IAB Europe TCF registry, this cookie is used exclusively to collect cross-site browsing behaviors and sync pseudonymous profiles across advertising networks. It does not carry raw Personally Identifiable Information (PII) like names or emails, but it tracks unique user patterns across independent websites for targeted marketing, placing it strictly within the Medium risk tier.
How to Remove mako_uid from a Website
To remove the mako_uid cookie from a website, the website administrator must completely remove the underlying Eyeota tracking script, pixel loader, or associated tag configurations deployed on the site. According to Eyeota's technical implementation guidelines, the mako_uid cookie is an essential operational component of their audience data collection infrastructure and cannot be disabled independently through a simple toggle or optional feature configuration. Because it serves as the core master browser identifier required for the platform's audience segmentation and cookie syncing functions to work, the administrator must completely excise the Eyeota code snippet from the website’s source code or completely deactivate and delete the Eyeota tag container within their Tag Management System (such as Google Tag Manager or Adobe Launch) to stop the cookie from being deployed.
