Google’s recent policy changes permitting advertisers to utilize IP addresses and device fingerprinting for ad targeting have ignited significant debate.
Critics argue that these modifications prioritize corporate profits over user privacy, potentially undermining the control individuals have over their personal data.
Understanding the Policy Shift
Historically, Google prohibited practices like device fingerprinting, which involves collecting detailed information about a user’s device and browser to create a unique identifier. This method allows advertisers to track users across the web without their explicit consent.
However, as of February 16, 2025, Google has revised its policies, now allowing the use of IP addresses and device fingerprinting for ad targeting purposes.
The company asserts that this change aligns with industry standards and is necessary to adapt to evolving technologies and user behaviors.
Critics’ Perspective
Privacy advocates express deep concern over this development. The UK’s Information Commissioner’s Office (ICO) labeled the change as “irresponsible,” emphasizing that fingerprinting reduces user choice and control over personal data collection.
Unlike cookies, which users can manage or delete, fingerprinting operates covertly, making it challenging for individuals to opt out or even be aware of the tracking.
Martin Thomson, a distinguished engineer at Mozilla, highlighted that by permitting fingerprinting, Google grants itself and the advertising industry the ability to employ tracking methods that users cannot easily prevent. This shift, he suggests, reflects a business-centric approach that may compromise consumer privacy.
Google’s Justification
In response to the backlash, Google maintains that the policy update is designed to balance user privacy with the needs of advertisers.
The company points out that competitors like Amazon and Meta already utilize IP addresses for ad targeting, and this move ensures parity within the industry.
Google also emphasizes its commitment to implementing privacy-safe technologies, aiming to protect user data while facilitating effective advertising.
Implications for Users
The primary concern with device fingerprinting and IP address tracking is the diminished ability for users to control their personal information.
These methods can compile extensive profiles based on browsing habits, device specifications, and location data, all without explicit user consent. This practice not only raises privacy issues but also exposes individuals to potential data breaches and unauthorized surveillance.
Industry Impact
For advertisers, access to IP addresses and device fingerprints can enhance ad targeting precision, potentially leading to higher conversion rates. However, this advantage comes with the risk of eroding consumer trust.
As awareness of privacy issues grows, users may seek alternatives that offer better data protection, potentially impacting brands that rely heavily on targeted advertising.

Google’s decision to permit IP address usage and device fingerprinting for ad targeting has sparked a contentious debate between the imperatives of effective advertising and the preservation of user privacy.
As the digital landscape continues to evolve, finding a balance that respects user autonomy while supporting industry needs remains a critical challenge.
FAQs
What is device fingerprinting?
Device fingerprinting involves collecting detailed information about a user’s device and browser to create a unique identifier, allowing for tracking across websites without the user’s explicit consent.
How does the use of IP addresses affect user privacy?
Utilizing IP addresses for ad targeting can reveal a user’s approximate location and, when combined with other data, contribute to detailed user profiling, potentially compromising privacy.
Why has Google changed its policy on fingerprinting?
Google asserts that the policy change aligns with industry practices and addresses the need for effective ad targeting in the face of evolving technologies and user behaviors.
